Omega Speedmaster Mark II 145.014

The Omega Speedmaster Mark II, reference 145.014, occupies a specific and irreversible position in Speedmaster chronology: it is the watch that proved the Speedmaster could exist outside the round case that had defined every reference since the CK2915 debuted in 1957. Introduced in 1969 and produced through approximately 1975, the 145.014 was simultaneously a commercial bet on the Speedmaster as a platform rather than a single watch, and a technical vehicle for engineering lessons learned from Omega’s classified Alaska Project prototypes developed for NASA extravehicular activity.

For collectors and dealers, understanding the 145.014 requires grasping a central irony: the watch that Omega designed partly for space was rejected by NASA, while the round Moonwatch it was meant to complement became the most famous wristwatch in history. That rejection, combined with a short production run and modest original marketing investment, kept the Mark II in relative obscurity for decades. The result is that the 145.014 now trades at roughly 40-60% of a comparable-era 145.022 Moonwatch despite sharing the exact same cal. 861 movement, the same factory, the same quality control, and the same production period. The racing dial variant amplifies this asymmetry further: the same grey-and-orange racing aesthetic that commands $50,000-$95,000 on a 145.022-69 Moonwatch can be acquired in a Mark II case for approximately $3,000-$5,000.

The 145.014 was the last Speedmaster Professional powered by the hand-wound cal. 861 to be housed in anything other than the traditional round case. Every subsequent Mark-series variant (III, IV, 4.5, V) moved to automatic movements. This makes the 145.014 the only tonneau-cased, hand-wound Speedmaster Professional ever produced, a distinction that cannot be replicated by any other reference in the Omega catalog.

Production volume has never been published by Omega. The reference was substantial enough to remain readily available on the secondary market today, with approximately 89 standard-dial listings appearing on Chrono24 at any given time, but far less common than the concurrently produced 145.022 Moonwatch. For the racing dial, Revolution Watch estimated approximately 150 units, roughly 1-3% of total 145.014 production, making it one of the rarest factory-original Speedmaster configurations of the era.

Collector note: Common names include “Racing dial” or “Exotic dial” (grey dial with orange/red checkered minute track), “Tropical” (black dial aged to brown or chocolate), “Gold cap” (145.034 gold-plated variant), and “Telestop” (wired remote-actuation variant for industrial timing). All stainless steel dial variants, standard and racing, share the same 145.014 reference number; the reference alone does not distinguish them.

Historical context and manufacturing

Why Omega built the Mark II

By mid-1969, Omega held two cards that no other watchmaker could match. The first was the Speedmaster’s freshly minted status as the first watch worn on the Moon, a marketing asset of incalculable value conferred on July 20, 1969, when Buzz Aldrin wore reference 105.012 (or, by some accounts, a 145.012 transitional) on the lunar surface during Apollo 11. The second was more than a year of classified research conducted under the code name “Alaska Project,” initiated in late 1967 at the request of NASA engineer James H. Ragan, who needed a chronograph capable of surviving the extreme thermal transitions of lunar EVA, where surface temperatures swing between approximately +250°F in direct sunlight and -250°F in shadow.

The Alaska Project produced its first prototypes (Alaska I, 1968-1969) in titanium with silvered, matte dials designed for maximum heat reflection and distinctive capsule-shaped chronograph hands optimized for readability under vibration. The titanium construction worked but proved prohibitively expensive for serial production. R&D expenditure on the project reportedly exceeded one million Swiss Francs. Omega needed to amortize that investment, and the answer was already on the workbench: the tonneau-shaped stainless steel case under development for a new consumer Speedmaster variant. The mineral crystal fitted to this case, as documented by the Omega Prototypes research group, “had proven to seal better against leaks and to withstand impacts without cracking” compared to the Hesalite crystal Ragan initially preferred. Ragan expressed appreciation for the case design, and Omega subsequently built a small number of Alaska Project test watches using the production Mark II case fitted with an outer protective shell of red anodized aluminum, designed for its high reflectiveness and superior heat resistance. At least one of these prototypes sold at Phillips auction in 2018 for CHF 193,750.

The Mark II thus served a dual purpose. Commercially, it allowed Omega to expand the Speedmaster from a single reference into a product family, capitalizing on the Apollo association without cannibalizing the Moonwatch. Technically, it recovered R&D value from the Alaska Project by incorporating the mineral crystal, flush-profile case architecture, and enhanced water resistance developed for space applications into a consumer-grade package.

Critically, the Mark II was never intended as a Moonwatch replacement. Omega kept the standard Speedmaster Professional 145.022 in continuous production throughout the Mark II’s entire lifespan and beyond, a decision that proved to be one of the most commercially significant in the company’s history given that the Moonwatch remains in the catalog to this day. The Mark II was a companion model: the same mechanical heart, a more contemporary case, positioned for the consumer who wanted a Speedmaster Professional without the round, lug-equipped architecture that had remained fundamentally unchanged since 1957. Period Omega advertising described the Mark II as the “same watch for earth and sea-bound adventurers,” explicitly framing it as the terrestrial counterpart to the Moonwatch.

The Mark II as a design landmark

The design significance of the 145.014 extends beyond Omega’s catalog. Every Speedmaster produced from 1957 through 1969, across references CK2915, 2998, 105.002, 105.003, 105.012, and 145.022, used some variant of a round case with exposed lugs. The progression involved incremental refinements: the addition of crown guards, the evolution from straight lugs to twisted “lyre” lugs, the growth from 39mm to 42mm. But the fundamental architecture remained that of a round, lugged chronograph.

The Mark II broke entirely with this tradition. Its tonneau case eliminated visible lugs, integrating the strap attachment points into a smooth, barrel-shaped form. The crown and pushers were recessed within the case contour. The external tachymeter bezel was relocated inside the crystal. The result was a watch with no protrusions, no exposed vulnerabilities, and a radically different visual identity from the Moonwatch it sat beside in the catalog. As Monochrome Watches observed, “the shape of the 45mm x 41mm case is seen nowadays as a typical 1970s style but the Mark II was one of the first watches to use that shape.”

This case philosophy, the elimination of visible lugs, the seamless transition from case to bracelet, the angular/tonneau form, directly prefigured the integrated-bracelet luxury sport watches that would define the 1970s. The Audemars Piguet Royal Oak (1972), the Patek Philippe Nautilus (1976), and the Vacheron Constantin 222 (1977) all explored similar territory. The Mark II was not a luxury-market product in the manner of what followed, but the design vocabulary was planted here first, alongside parallel evolutions like the Heuer Autavia third-generation (reference 1163, also 1969).

Catalog position among contemporary Speedmaster references

During the Mark II’s production run, the Speedmaster catalog was at its most diverse. Understanding what surrounded the 145.014 clarifies its market position and why certain watches are sometimes confused with it.

Reference	Model	Years	Caliber	Distinguishing feature
145.012	Speedmaster Professional	1967-1969	321 (manual, column wheel)	Final column-wheel Speedmaster; Apollo 11 reference
145.022	Speedmaster Professional Moonwatch	1968-ongoing	861 (manual, cam-switched)	Direct contemporary; identical movement; continuous production
BA 145.022	Speedmaster Professional (18K gold)	1969	861	Solid gold; presented to astronauts at Houston gala dinner
145.014	Speedmaster Mark II	1969-c.1975	861	Tonneau case; mineral crystal; internal tachymeter; 120m WR
176.002	Speedmaster Mark III	1971-1973	1040 (automatic)	First automatic Speedmaster; three case sub-variants
176.009	Speedmaster Mark IV	1973-1974	1040 (automatic)	Tonneau; modular inner-case construction; 41.4mm
176.0012	Speedmaster Mark 4.5	1974-early 1980s	1045 (automatic, Lemania 5100)	Similar to Mark IV; different movement family
(no ref.)	Speedmaster Mark V	1984	1045 (automatic)	German market only (“Teutonic”); ~40,000 pieces

There is no official “Mark I.” The naming convention borrows from aviation and military nomenclature (Spitfire Mark I through Mark 24) and implies the original Speedmaster Professional constitutes the first iteration. Omega never retroactively designated any prior reference as Mark I. The Mark II and Mark IV are the only models in the series to consistently bear “Professional” on the dial; the Mark III carries it on some but not all examples.

Also produced during this window: the Speedmaster 125 (ref. 178.002, 1973), a massive commemorative piece with the world’s first chronometer-certified automatic chronograph movement, limited to approximately 2,000 pieces; the Flightmaster (1969), a pilot chronograph using caliber 910 (an 861 derivative with GMT complication); and the Speedsonic f300 (“Lobster”), a tuning-fork-powered chronograph reflecting Omega’s experimentation with electronic movements.

Manufacturing

All Mark II watches were manufactured at Omega’s facilities in Biel/Bienne, Switzerland, the company’s headquarters since the late 19th century. Caliber 861 movements were produced by Lemania, a sister company under the SSIH (Société Suisse pour l’Industrie Horlogère) umbrella since 1932. Case fabrication and final assembly took place at the Omega plant, on the same production line and with the same quality control as the Speedmaster Professional 145.022.

The NASA rejection and space program connection

The Mark II was never flight-qualified by NASA and was never issued to astronauts for mission use. As Fratello Watches documented, “NASA was approached to take a look at the new Speedy but apparently could not fit the testing into its tight mission scheduling.” The only watches formally qualified by NASA for manned spaceflight during this period were the standard-case Speedmaster Professional references (105.012 and 145.022).

The Alaska Project connection partially counterbalances this rejection. After the titanium Alaska I prototypes proved too costly, Omega built subsequent Alaska Project test watches using the production Mark II case with the red anodized aluminum outer shell. While these were ultimately not selected for NASA missions (Omega reverted to the classic lyre-lugged case for the Alaska II series), the watches did see actual space duty: according to research published in SpaceFlight magazine, Soyuz 25 cosmonauts Vladimir Kovalyonok and Valeri Ryumin wore Alaska II Speedmasters with red outer cases on the left forearms of their Sokol spacesuits in 1977, and further EVA use occurred in 1978. This gives the Mark II a credible space-development backstory that the collector community increasingly recognizes, even though the watch itself never flew with NASA.

Military issue and motorsport

There is no documented evidence of formal military issue of the 145.014 by any national armed force. The “Professional” designation on the dial refers to Omega’s product positioning rather than institutional adoption; Omega began using the word on the Speedmaster dial in 1965, coinciding with the NASA flight qualification, and applied it to the Mark II as branding continuity.

The Speedmaster’s origins, however, are more closely tied to motorsport than to space. The original CK2915 debuted in 1957 with advertisements depicting men in sports cars, and the tachymeter bezel was designed for timing laps and measuring average speed. This motorsport heritage persisted through the Mark II era. Luca Cordero di Montezemolo, who managed Scuderia Ferrari’s Formula 1 team and later served as president and chairman of Ferrari, was documented wearing a Mark II habitually. The racing dial variant directly invokes this lineage, its bold grey, orange, and red color scheme designed for rapid chronograph readability at a glance, the same functional logic behind the earlier 145.012 “Red Racing” and 145.022 “Orange Racing” dials.

Period advertising

From December 1969 onward, virtually all Speedmaster advertising centered on the tagline “The First Watch Worn on the Moon.” Within this campaign, the Mark II appeared in supporting roles. A 1970s-era advertisement featured six “legendary” Omega watches, describing the Mark II as the “same watch for earth and sea-bound adventurers.” A 1971 advertisement specifically featuring the Mark II attempted to build on the Professional’s space reputation.

The racing dial variants were catalog options, not the centerpiece of any dedicated promotional effort. Omega did not mount a motorsport-focused advertising campaign for the Mark II until the mid-1990s, when the brand began actively leveraging Speedmaster racing heritage through its partnership with Michael and Ralph Schumacher (beginning in 1996). The 2004 Speedmaster Professional “Japan Racing” limited edition (ref. 3570.40.00, limited to 2,004 pieces, Japan-exclusive) was directly inspired by the Mark II and 145.022-69 racing dials.

The retail price at introduction was approximately $195, compared to $175 for the standard Speedmaster Professional 145.022, reflecting the more complex case construction and mineral crystal. This is a notable detail: the Mark II was actually more expensive at retail. That value relationship has completely reversed in the secondary market.

Production timeline

Introduction and production concentration

The 145.014 was introduced in 1969, with consistent commercial production beginning that year. The reference remained in production through approximately 1975, but the bulk of production was concentrated between 1969 and 1973. Some sources cite discontinuation as early as 1972, coinciding with the introduction of the Mark III, though documented examples with serial numbers corresponding to 1973 and beyond exist. The most defensible position is that primary production occurred between 1969 and 1973, with residual assembly or distribution extending as late as 1974 or 1975.

Unlike Rolex, Omega has not published official production volume figures for the 145.014. No reliable third-party estimate exists. For the racing dial variant, Revolution Watch estimated approximately 150 units, making it roughly 1-3% of total 145.014 production.

Serial number ranges by production year

The serial number on the Mark II is found on the movement itself, engraved on a bridge of the caliber 861. It is not on the exterior of the case or caseback. To access the serial, the caseback must be removed. The following ranges are Speedmaster-specific and represent approximate earliest production years for each serial block. They differ from the general Omega production serial chart.

Movement serial range	Estimated production year
27,000,000 – 27,999,999	1969
28,000,000 – 30,999,999	1970/1971
31,000,000 – 31,999,999	1972
32,000,000 – 32,999,999	1973
33,000,000 – 33,999,999	1975

Documented examples carry movement serials within the 29,xxx,xxx to 35,xxx,xxx range. A representative 1969 example documented by Craft and Tailored carries a serial in the 29,6xx,xxx range. HODINKEE documented examples with serials as high as 35,582,904 (dated 1972/1973). A verified example with serial 32,191,860 was confirmed by the Omega Archives as September 1971 delivery. Examples in the 30,xxx,xxx range (1970/1971) appear to be the most common.

A movement serial outside the 27,000,000-33,000,000 range warrants immediate scrutiny. A serial in the 40-million range, for example, would indicate a movement produced in the 1980s and is certainly a replacement. For definitive production dating of an individual watch, an Extract from the Archives may be obtained directly from Omega for approximately CHF 120. The ilovemyspeedmaster.com production date prediction tool cross-references movement serials against actual Extract data submitted by collectors and is the most precise publicly available dating resource.

Construction and architecture

Case design

The 145.014 case is stainless steel in a tonneau (barrel) shape with fully integrated, hooded lugs. This is the defining physical characteristic of the watch and the feature that separates it, at a glance, from every other Speedmaster reference produced before or since (until the 2014 re-edition). The case eliminates all protrusions: no visible lugs extend from the case body, no crown guard flanges project at 3 o’clock, and the chronograph pushers barely extend past the case surface. The effect is a smooth, continuous form that anticipates the integrated-bracelet philosophy of the 1970s.

Dimension	Measurement
Width (across case, excluding crown/pushers)	41.1 – 42.0mm (commonly cited as 41.7mm)
Length (lug to lug)	45.0 – 45.5mm
Thickness (caseback to crystal)	14.0 – 15.0mm
Lug width (spring bar span)	20mm
Water resistance (original rating)	120m / 10 ATM
Weight on bracelet	~134g

Despite its visual presence, the lug-to-lug measurement of approximately 45mm is compact relative to the case width, which is part of why the watch wears smaller than its dimensions suggest. Viewed head-on at the lugs, relatively little metal surrounds the spring bar channel, giving the ends a slender profile.

Case finishing: five distinct zones

The Mark II case carries five distinct surface zones, each with a specific factory finish. This multi-zone finishing is a signature element and the first thing destroyed by improper polishing. Understanding each zone is essential for both authentication and condition grading.

Zone 1: Top surface (dial side). Radial sunburst/starburst striations emanate outward from an imaginary center point above the dial, terminating at a sharp transition line into the side chamfer. This finish is the visual hallmark of the Mark II and is easily identified under raking light.

Zone 2: Upper chamfer. Mirror polished, geometrically flat. This is the transition band between the sunburst top and the brushed flanks. On an unpolished case, the chamfer meets the top surface at a crisp 90-degree break. This edge is the first casualty of polishing; it rounds into a gradual curve that can never be restored without laser welding.

Zone 3: Case sides (flanks). Straight longitudinal brushing (vertical satin brush), running parallel to the case height.

Zone 4: Lower chamfer. Mirror polished, matching the upper chamfer.

Zone 5: Caseback. Factory texture with hippocampus relief.

Authentication note: To check finishing integrity, photograph the case at a raking angle with a light source at 45 degrees across the top surface. Surviving sunray striations will produce a distinctive directional reflection pattern. Photograph the chamfer transition straight on: any rounding shows as a gradient in the reflection rather than a sharp line. Reflect a straight-edged light source off the polished chamfer: a mirror-flat chamfer reflects the line straight; a rounded chamfer distorts or curves it. Severe cases require laser welding to restore lost material.

Caseback

The caseback is screw-down stainless steel. The exterior bears the classic pre-Moon hippocampus (seahorse) medallion in bas-relief at center, with “Speedmaster” arched above it. No NASA flight-qualification inscriptions, no Apollo commemorations, no additional text. The hippocampus traces its origins to the Seamaster line (1957), and its presence on the Speedmaster reflects the shared ancestry of the Speedmaster, Seamaster 300, and Railmaster within the original 1957 tool watch family.

The hippocampus impression was intentionally rendered with modest depth by Omega. On well-worn examples, both the seahorse and “Speedmaster” text are frequently faint due to decades of wrist contact and, in some cases, polishing. This faintness is normal and expected, not a forgery sign. A caseback reading “Seamaster” rather than “Speedmaster” is incorrect; this swap is documented in the market, as some Mark IIs left the Omega service network with Seamaster casebacks installed.

The interior carries stamped (not engraved) text: the reference number “145.014” (or “ST 145.014”), the Omega triangle logo (“OMEGA WATCH CO.”), “ACIER INOXYDABLE” (stainless steel), and “FAB SUISSE” or “SWISS MADE.” The distinction between stamped and engraved is a critical authentication point: authentic Omega casebacks show letters of consistent height with square edges (the “E” in “ACIER” has straight, right-angled arms), and the Omega triangle logo shows the “M” and “A” at approximately 80% of surrounding letter height. Fraudulent casebacks show engraving lines (V-cut), inconsistent letter heights, and misshapen proportions.

Omega’s service replacement caseback is designated 145.0014, adding a zero consistent with updated reference numbering conventions applied to service parts. HODINKEE explicitly notes service casebacks on their listings. A service caseback reduces strict originality but is not disqualifying.

Dial variants

Reference 145.014 was produced with two stainless steel dial configurations sharing the same reference number. Omega did not assign separate sub-references. This means the reference alone cannot distinguish between a $2,500 standard dial example and a $5,000+ racing dial example, making physical inspection essential for any transaction.

Standard dial (matte black)

The standard production dial is matte black, glare-resistant, with printed white Omega symbol at 12 o’clock. The Omega logo on the 145.014 is painted (not applied metal), consistent with the tool-watch ethos of the Speedmaster Professional line and distinguishing it from the 145.034 gold variant, which uses applied metal indices. The text hierarchy reads, from 12 o’clock downward: the Omega horseshoe symbol, “OMEGA,” “Speedmaster” in italic script, “PROFESSIONAL,” and “MARK II.” The “Mark II” designation is the key textual distinction from the standard Moonwatch dial, which lacks this text.

At 6 o’clock: “T SWISS MADE T” on tritium-marked examples. However, not all Mark II dials carry the “T” designation. Per ISO 3157, tritium labeling with “T” was mandatory only when the radioactive content exceeded a specified threshold. Some legitimate original dials read simply “SWISS MADE” without the flanking T marks. The absence of “T” alone is not necessarily an indicator of a replacement dial, though it warrants inspection in context with other originality markers. Tritium-marked dials tend to age toward cream-to-pumpkin tones, while some unmarked (lower-tritium) examples have been observed aging to a greenish-lime hue.

Hour markers are printed white baton/stick indices with tritium fill, positioned at each hour except where obscured by subdials. Three slightly recessed (countersunk) subdials sit at 3 (30-minute chronograph register), 6 (12-hour chronograph register), and 9 o’clock (running seconds). Register numerals are oriented vertically (upright).

Racing dial (matte grey, “exotic dial”)

The most collectible stainless steel variant features a matte grey (not black) dial surface with the Omega logo printed in orange at 12 o’clock, an immediately distinctive identification point that is unique within the Speedmaster family. “OMEGA” text appears in orange; “Speedmaster,” “PROFESSIONAL,” and “MARK II” remain in white. The “Mark II” text is the key distinction from the near-identical racing dial used on the 145.022-69 Moonwatch, which does not carry this designation.

The defining visual feature is the outer seconds/minutes track: an alternating checkered pattern in segments of orange, red/magenta, and white against the grey dial background, evoking a racing flag motif. This pattern is the feature that gives the dial its “racing” or “exotic” designation. The orange paint on the minute track is UV-reactive, a period-correct characteristic that can be verified with a blacklight. Subdials are countersunk with concentric detailing, matching the standard dial layout.

The racing dial is directly related to the rarest and most expensive Moonwatch variants. The same racing aesthetic on a 145.022-69 commands $50,000-$70,000. The Mark II racing dial trades at roughly 1/15th that price for the same movement and the same dial character. This disparity is the central “value thesis” articulated by every major collector publication covering this reference.

The dial step

Original 145.014 dials have a physical step (change of plane) between the outer minute track and the central plate. This stepped/countersunk construction makes the registers appear slightly recessed, adding visual depth. The absence of this step on a presented “original” dial is a reliable indicator of a service or replacement dial. Under raking light or with a loupe, the step should be clearly visible as a shadow line around the inner perimeter of the minute track ring. Omega service dials from the post-tritium era are identifiable by three characteristics: no T marks, no step between minute track and central plate, and SuperLumiNova lume that glows brightly and persistently after light exposure.

Hands

The correct handset differs between dial variants, and this is one of the most important authentication points on any 145.014 transaction, particularly for the racing dial.

Standard black dial hand set:

• Hour and minute: White-painted luminous sword/baton hands with tritium fill, matching the Speedmaster Professional style. The minute hand measures 13.5mm; the standard 145.022 Moonwatch minute hand is 14mm. This 0.5mm dimensional difference is significant: Moonwatch hands will visibly overhang subdial rings on a Mark II and are immediately identifiable as incorrect.
• Central chronograph seconds: Long, white-painted with a luminous tip.
• Subdial hands: Thin, white or steel-colored, without luminous material. All three subdial hands are white.

Racing dial hand set:

• Hour and minute: White sword hands with a grey/dark central section near the base, creating a “floating” visual effect. The grey section blends into the grey dial while the white outer section contrasts sharply. This design trick is comparable to the technique used on the Rolex Explorer II ref. 1655 “Steve McQueen.” Tritium lume fill is present on both.
• Central chronograph seconds: Orange.
• 30-minute register (3 o’clock): Orange.
• 12-hour register (6 o’clock): Orange.
• Running seconds (9 o’clock): White (not orange). This mixed-color scheme is the correct factory configuration and non-negotiable. An all-orange subdial hand set is incorrect.

The watch never shipped with orange hour and minute hands. This is the most common hand fraud on the racing dial variant: orange hour/minute hands sourced from Seamaster chronograph donor parts of similar vintage are frequently substituted but are incorrect. The correct racing dial hour and minute hands have the grey/dark base sections; fully orange hands are wrong. Additionally, any racing dial 145.014 where the running seconds hand at 9 o’clock is orange rather than white has been assembled incorrectly.

Luminescence: tritium markings and aging

All 145.014 production used tritium as the luminous compound on both hands and dial indices. Tritium has a half-life of approximately 12.3 years, meaning that after 50+ years (four half-lives), only about 6% of the original radioactive content remains. All original-tritium Mark II examples are now fully inert and no longer glow in darkness.

On an unserviced, unaltered 145.014, correct tritium aging presents as follows: plots should show a warm cream to deep tan color, with the most common and aesthetically prized state being even yellowing in the warm yellow to honey range. Hands typically age somewhat faster and darker than dial plots due to greater exposure; a small degree of mismatch in this direction (hands slightly darker) is normal and expected. The reverse mismatch (hands lighter or whiter than plots) is suspicious and is the most common indicator of replaced or relumed components.

Stage	Appearance	Notes
Light	Cream / off-white	Regular wear and UV exposure during lifetime
Medium	Warm yellow to honey	Most common; considered aesthetically ideal by collectors
Heavy	Amber, tan, caramel	Associated with dark storage conditions
Extreme	Brown to near-black	Unusual; may indicate moisture ingress or extreme conditions

Moisture ingress causes the tritium layer to disappear, leaving the underlying phosphor/paint, which often produces a greenish or abnormal coloration. This is damage, not collectible patina.

Crown

The crown is a signed, push-pull type (not screw-down), smaller and stubbier than the crown on the standard Speedmaster Professional. It sits nearly flush with the case profile, barely protruding past the case surface. The push-pull design provides two positions: pushed in for manual winding of the cal. 861, and pulled out for time setting. Because the cal. 861 is non-hacking, pulling the crown does not stop the seconds hand.

Specification	Detail
Part reference	069ST43059
Thread (tap)	Tap 9 (0.90mm pitch)
Crown diameter	6.20mm
Crown depth	3.95mm
Pendant tube diameter	2.50mm
Cross-compatible references	145.014, 145.007, 145.013, 145.020

Crystal

The 145.014 uses a flat mineral glass crystal (not hesalite/acrylic, not sapphire), sitting nearly flush with the top of the case. This was a deliberate departure from the domed hesalite on the standard Speedmaster Professional and a direct inheritance from the Alaska Project’s emphasis on crystal sealing and impact resistance.

The tachymeter scale is silk-screened on the underside of the crystal in black, graduated to 500, fully protected from external wear. This placement eliminates the common wear point of a traditional aluminum bezel insert. Unlike the Speedmaster Professional Moonwatch, where the “Dot Over 90” crystal variant is a significant collector consideration, the Mark II has no such complication. Service and original crystals are functionally and visually identical, though tachymeter font sizing may vary between production eras.

Part reference: 063TN5146TA (tachymeter version). Crystal diameter: 36.5mm. Fits case references 145.014, 145.0014, 145.026, and 145.0026. A telemeter variant also exists (063TN5146TE1). Replacement crystals (genuine Omega and aftermarket) are readily available.

Bezel

The Mark II does not have a conventional external rotating or fixed bezel insert. The case has a smooth, polished upper rim with no separate bezel component. The tachymeter function is accomplished entirely by the crystal-printed scale. This means there is no bezel insert to scratch, fade, or replace, which contributes to the generally well-preserved appearance of many surviving examples. While the standard tachymeter scale is overwhelmingly the most common, some Mark II models were also produced with alternative crystal scales (pulsometer, telemeter, decimal, yachting). These non-tachymeter variants are rare.

Pushers

Two round chronograph pushers sit at 2 o’clock (start/stop) and 4 o’clock (reset), integrated into the case flank with minimal protrusion. Cap diameter: 5mm. Overall length: 7.20mm. Pump-style (not screw-down), stainless steel, supplied with washer. The pushers operate the cam-actuated chronograph mechanism of the cal. 861.

Bracelet and endlink references

The Mark II was supplied on stainless steel bracelets, with four documented factory configurations spanning the production run. The bracelet is an integral part of the Mark II’s design language: the endlinks nest within the hooded lugs, creating a seamless case-to-bracelet transition that was central to the tonneau aesthetic. Despite this integrated appearance, the system uses conventional 20mm spring bars and straight-end links, allowing any 20mm strap as an alternative.

Ref. 1159 with endlinks 154 (~1969): The earliest bracelet, used on first-year production. The same bracelet reference used on the Flightmaster (with different endlinks on that model). Features two polished intermediate links between the brushed outer links, giving a visually distinctive brushed/polished two-tone appearance. Friction-fit pins. Folding blade clasp stamped “OMEGA” and “STAINLESS STEEL.” Relatively rare, as it was used only during the initial production period.

Ref. 1116 with endlinks 154 (~1969): Visually similar or identical to the 1159. The precise distinction (possibly pin vs. screw link construction or minor dimensional differences) is not conclusively documented in published references. Also seen on early production.

Ref. 1158 with endlinks 154 (early production): A less common factory configuration, documented on at least one racing dial example by Craft and Tailored.

Ref. 1162 with endlinks 173 (~1970 onward): The canonical Mark II bracelet, found on the majority of surviving examples. A variation on the well-known Omega 1171 bracelet used on the contemporary Moonwatch, adapted with straight endlinks for the Mark II’s hooded lug geometry. All-brushed stainless steel links, 20mm tapering to approximately 16mm at the clasp. Vintage examples use friction-fit split pins for link removal and sizing. Folding blade clasp stamped “1162/173,” “OMEGA,” and “STAINLESS STEEL.”

The 1171/633 Moonwatch bracelet is not correct for the Mark II. Its 633 endlinks will not nestle flush into the hooded lug recess and will visibly break the case/bracelet transition. Endlink reference numbers (173 or 154) should be stamped on the inner face of the endlink itself. Unstamped endlinks are suspicious.

Bracelet ref.	Endlink ref.	Period	Notes
1159	154	1969	Two polished intermediate links; shared with Flightmaster
1116	154	1969	Similar/identical to 1159; distinction not conclusively documented
1158	154	Early	Less common; documented on racing dial example
1162	173	1970 onward	Most common; all-brushed; adapted from Moonwatch 1171

Clasp date codes on the 1162 use two numbers: the first indicates quarter of manufacture (1-4), the second indicates year (two digits). Example: “4 71” = Q4 1971. Some early 1970s clasps use month numbering rather than quarter numbering (e.g., “10 71” = October 1971). The clasp can be swapped independently, so its date indicates when that clasp was made, not necessarily the watch. No date code is not a red flag; some vintage clasps have worn or illegible stamps.

Modern Omega service replacement 1162/173 bracelets use screw-in links rather than the original friction-fit pins. Screw heads visible on link undersides identify these immediately. The modern service bracelet is a genuine Omega part but not a period-correct vintage component, available from Omega at approximately $500.

Material and reference variants

Steel reference 145.014

The stainless steel 145.014 in its standard and racing dial configurations is the canonical Mark II described throughout this report. The official Omega Heritage Department position, as communicated in correspondence with collectors, is that 145.014 denotes stainless steel only. Omega’s reference prefix system of this era confirms: “ST” = Stainless steel (Stahl/Steel), as in ST 145.014.

Gold-plated reference 145.034

The gold-plated (rolled gold, “métal doré”) Mark II carries a distinct reference number, 145.034 (prefix MD). It features a gold/champagne dial with applied metal Omega logo and hour indices (not printed, as on the steel version), radially oriented register numerals (as opposed to vertical orientation on the 145.014), and a burgundy/maroon tachymeter scale on the crystal. The movement is the same cal. 861.

Case dimensions are nearly identical: 41.75mm diameter, 45.2mm lug-to-lug, 14.3mm thick. Production ran from approximately 1972 through 1976, with documented examples dated to 1970, 1973, 1974, and 1976.

The gold-plating process did not age well, making survivors in presentable condition quite scarce. As Analog:Shift has noted, the 145.034 is the rarest execution of the Mark II and the most difficult to find in good condition. Despite this scarcity, it paradoxically commands lower prices than the stainless steel standard or racing variants ($1,500-$3,500 vs. $2,000-$5,500+) due to reduced collector interest in gold-plated pieces generally.

Omega has denied Extract from the Archives requests for stainless steel watches submitted under the 145.034 reference. A persistent debate exists on Omega Forums regarding whether stainless steel examples bearing 145.034 exist as legitimate factory configurations. The safest guidance for dealers and collectors: treat the Heritage Department position as authoritative. 145.014 = stainless steel. 145.034 = gold plated.

Telestop variant

A particularly unusual variant is the Speedmaster Mark II Telestop, which incorporated a mechanism allowing the chronograph pushers to be activated remotely via a wired connection. This was intended for scientific or industrial timing applications where the operator could not physically reach the watch. The Telestop also carries the 145.014 reference number. It is extremely rare and seldom encountered in the market.

The tropical phenomenon

Standard black-dial examples are susceptible to tropicalization, where the matte black lacquer surface turns warm brown or chocolate through UV exposure and chemical aging over decades. The phenomenon is most commonly seen on watches that were worn daily in warm, sun-exposed climates.

The patina spectrum ranges from subtle cream undertones through full chocolate brown. Authentic tropical dials show the color change uniformly across the dial surface with intact lacquer (no flaking, blistering, or cracking) and clean original lume. Brown coloration concentrated around seams, springbar holes, or the crown tube area is a sign of moisture damage, not UV-induced tropical fading.

Tropical examples are actively sought by a subset of collectors and command a premium over non-tropicalized standard dials in comparable condition, typically $3,000-$4,500 versus $2,500-$4,000 for equivalent non-tropical examples. The Mark II’s relative affordability compared to the 145.022 means that tropical 145.014 examples were less aggressively preserved, making unserviced originals harder to find than tropical Moonwatches of the same era.

Movements and calibers

Caliber 861: the Moonwatch engine in a tonneau case

The movement powering the 145.014 is the cal. 861, a hand-wound chronograph introduced in 1968 as the replacement for the legendary cal. 321. The 145.014 was fitted exclusively with the cal. 861 for its entire production run. There are no known sub-variants (861L, 864, 866) used in this reference, and no mid-production caliber changes occurred during the 1969-1975 window.

The cal. 861 is, in every functional respect, the same movement used in the Speedmaster Professional Moonwatch 145.022 and the Sea-Dweller-adjacent Flightmaster. A collector who has handled a Moonwatch movement from the same era will recognize the 861 in a Mark II immediately. The shared caliber is the foundation of the Mark II’s claim to Moonwatch-equivalent mechanical credibility.

Why the 861 replaced the 321

The critical technical distinction between the 861 and its predecessor 321 lies in the chronograph switching mechanism. The 321 used a column wheel, a more traditional and costly component generally regarded as providing smoother chronograph actuation. The 861 replaced this with a cam-operated (shuttle) mechanism derived from the Lemania 1873, which was simpler to manufacture and more resistant to shock. The lateral clutch design also contributed to durability. The 861’s higher beat rate (21,600 vph versus the 321’s 18,000 vph) improved rate stability and timing resolution. The transition was driven by manufacturing efficiency and improved robustness, not by a reduction in quality.

The 861 remained in production until 1996, when Omega introduced the cal. 1861, an essentially identical movement distinguished primarily by its rhodium-plated finish (the 861 used a copper/gilt finish). The 1861 continued to power the Moonwatch through 2019, succeeded by the cal. 3861.

Caliber comparison: predecessor and successor

Caliber	Base	Chrono mechanism	Frequency	Finish	Production
321 (predecessor)	Lemania 2310	Column wheel	18,000 vph	Gilt	1942-1968
861	Lemania 1873	Cam/shuttle	21,600 vph	Copper/gilt	1968-1996
1861 (successor)	Lemania 1873	Cam/shuttle	21,600 vph	Rhodium	1996-2019

Visual identification and authentication of the cal. 861

Plating color is the most critical first test when the caseback comes off. For 1969-1972 production, the correct finish is rose-gold/copper-toned gilt plating on all brass bridges and the main plate. The plating is galvanically applied and nearly pure copper. This warm amber/copper tone is immediately distinguishable from two common substitutions:

• Bright yellow-gold plating: Indicates a movement dated approximately 1992-1996 (later cal. 861 production). Not period-correct for a 145.014.
• Silver/grey rhodium plating: Indicates a cal. 1861 movement (post-1996). Immediately identifiable and represents a non-original, service-replaced movement that significantly reduces collector value.

Bridge architecture: The cal. 861 uses a 3/4-plate layout with a distinctive large train bridge colloquially described as resembling a map of Australia. A separate barrel bridge covers the mainspring barrel. The balance cock positions the balance wheel at approximately 7-8 o’clock. Heart-shaped upper and lower cams for the chronograph mechanism are visible at approximately 12 o’clock, replacing the column wheel of the cal. 321. This cam is one of the most visually distinctive identifying features of the 861 family.

Coupling wheel cock: In the original cal. 861, the coupling wheel cock is German silver and appears distinctly lighter/more silvery-grey than the copper-plated brass bridges, creating a natural two-tone effect. The cal. 1861 replaced this with a steel or rhodium-plated brass version. If all components appear uniformly silver, the movement is a cal. 1861.

Decoration: The standard cal. 861 (solid caseback version, which is the only version used in the 145.014) has machine-applied parallel stripes only, with smoothly finished (not beveled) edges. Geneva stripes and polished edges appear only on the cal. 861L/863 (display caseback versions) and cal. 1863. If a movement from a 145.014 shows Geneva stripes, it is either a cal. 863 incorrectly installed or a non-original movement.

Chronograph brake: Early cal. 861 (1968 to circa 1973) used a metal brake for the chronograph seconds hand. Later production adopted a Delrin (nylon-like) plastic brake, visible as a small white or off-white component above the central chronograph wheel. For a 1969-1972 145.014, the original brake is metal. A Delrin brake does not necessarily indicate a swapped movement, as Omega used Delrin in replacement parts from the 1970s onward during legitimate servicing. However, a metal brake on a confirmed early example is a positive indicator of untouched internals.

Movement markings: The cal. 861 carries “OMEGA” engraved prominently on a movement bridge, “17 JEWELS” on the plate or bridge, and the 8-digit movement serial number adjacent to the Omega signature. The designation “CAL. 861” does not typically appear engraved in a collector-visible sense. The technical designation “27 CHRO C12 PC” appears in factory documentation but is not typically visible on the movement itself.

Authentication guide

Authentication priorities in order of impact

When assessing a 145.014, the following sequence reflects both the frequency of fraud and the value impact of each component. A problem at step 1 or 2 should halt the transaction or trigger a significant price adjustment before further inspection.

1. Movement serial number: Should fall within the 27,xxx,xxx to 33,xxx,xxx range for the 145.014 production era. A serial outside this range is certainly a replacement movement.
2. Movement plating: Copper/gilt = period-correct cal. 861. Rhodium = cal. 1861 service replacement. Yellow-gold = late-production 861, not period-correct for this reference.
3. Dial originality: Font characteristics, T SWISS MADE T marking, dial step, print quality, and condition coherence with case and hands.
4. Tritium patina matching: Color temperature between dial plots and hand lume should be broadly consistent. Dramatic mismatches indicate parts swaps.
5. Hand set correctness: For racing dials, verify the grey-base hour/minute hands and the white (not orange) running seconds hand at 9 o’clock.
6. Caseback stampings: Stamped (not engraved) “145.014,” correct Omega triangle, “ACIER INOXYDABLE.” “Speedmaster” (not “Seamaster”) on exterior.
7. Case finishing: Surviving radial sunburst on top surface, sharp chamfer edges, longitudinal brushing on flanks.
8. Bracelet reference and endlinks: Correct 1162/173 (most common) or 1159/154, 1116/154 (early) with stamped endlink reference.

Dial authentication

The single most consequential authenticity question on any 145.014 is whether the dial is original. The watch’s relative affordability compared to the 145.022 Moonwatch has historically made it a candidate for dial-swap conversions, cost-cutting restorations, and outright redialing. The fastest tell is a mismatch in aging: if the case shows significant wear and the bracelet has honest stretch, yet the dial looks freshly printed with crisp text and uniform matte finish, something is wrong.

Font characteristics for period authentication:

• “OMEGA” text: At its largest and broadest in classic Speedmaster history for the 145.014’s early 1970s production window, with tight letter spacing (closer kerning than either 1960s or post-1980s versions) and maximum stroke weight for the era. A dial showing thinner “OMEGA” text with wider letter spacing is consistent with a post-1980s service dial.
• “Speedmaster” script: Shows an aggressively elongated “S” that descends alongside the “p” descender, and a sharp, aggressive downward dive on the “r” below baseline. These proportions are more exaggerated than in later 1980s versions, where both letters are more constrained and rounded.
• “PROFESSIONAL” and “Mark II”: Clean sans-serif uppercase with uniform stroke weight and symmetric spacing.
• Omega horseshoe symbol: Painted white on all production 145.014s. The transition from applied metal to painted symbol occurred around mid-1969, contemporaneous with the Apollo 11 mission. Any 145.014 with an applied metal Omega logo is suspect.

The “T SWISS MADE T” marking: All period-original 145.014 dials carry this marking at 6 o’clock. A dial missing the flanking T characters on a 1969-1973 watch is a significant red flag. It indicates either a service/replacement dial produced after 1994 (when tritium was phased out) or a redial. This text sits on the concave/stepped edge of the dial and is difficult to reproduce correctly; most redial operators omit it entirely, which makes its absence the fastest single redial tell on a 145.014.

Distinguishing original dials from refinished or repainted dials:

• Print quality under magnification (10x-30x): Factory original dials are printed industrially with uniform ink density, razor-sharp edges, and consistent letterform thickness. Redials show irregular ink edges, variable line thickness within the same letter, blurring between text and background, and inconsistent character spacing. Overlapping print areas where minute track hash marks run close to the outer dial edge, or where subdial rings intersect with track markings, are particularly revealing: factory printing handles overlaps cleanly, while hand redialing produces smudging at intersections.
• Internal font consistency: Assess whether the “3” in one position matches the “3” in another across the dial. Internal inconsistencies within a single dial are diagnostic of a redial.
• Paint under applied elements: Under strong loupe, check the boundary between hour marker indices and the adjacent dial surface. On a refinished dial, traces of new paint may appear on the underside or edges of applied elements where the dial was painted after these parts were glued down.
• Glue deposits at index bases: When a redial operator removes hour markers to repaint, they reattach them with adhesive. Traces of excess glue, visible under magnification as slight haze, ridging, or discoloration at marker bases, indicate removal and reattachment. Markers at unusual angles relative to their correct radial alignment confirm tampering.
• Surface finish: Original matte black (standard) and matte grey (racing) surfaces have specific factory textures. A refinished dial tends to look too smooth and uniform, with a slightly glossy appearance because new paint fills microscopic surface texture. Under raking light, an original shows subtle dimensionality; a redial appears flat.
• Singer marking on dial reverse: Some Speedmaster dials carry a faint “SINGER” stamp on the reverse (Singer being the Swiss dial maker that supplied Omega). Its presence provides corroborating evidence; its absence is not conclusive.

UV testing

Under UV/blacklight (365nm or 395nm), aged original tritium fluoresces a warm yellowish-orange to cream color and fades quickly (within seconds) when the UV source is removed. SuperLumiNova or LumiNova (used in relumes and modern service dials) fluoresces bright green and holds a persistent afterglow for minutes to hours. For heavily degraded tritium on a 50+ year old piece, the UV response may be very faint or nearly invisible; this is expected and normal, not evidence of a problem.

Field test procedure: Take the watch from sunlight into a dark room. Expose the dial and hands to a UV flashlight for 10-15 seconds. Remove the UV light rapidly. If the watch glows brightly for minutes: the lume is almost certainly SuperLumiNova. A relume has occurred. If the watch shows only a brief flash that fades within seconds: consistent with aged tritium.

The orange paint on the racing dial’s minute track is itself UV-reactive, reflecting vividly under blue/UV light. This is a period-correct characteristic of the 145.014 racing dial and should not be confused with a relume indicator.

Signs of reluming

• Consistency test: On a wholly original, unserviced watch, lume on dial indices and hands will have aged identically: same color, same UV reactivity, same nighttime glow behavior. Whiter, brighter lume on the hands than on the dial indices is the most common mismatch signal.
• Size and shape of lume plots: Original factory lume is applied in consistent, uniform quantities. After 50 years, plots may have slightly shrunk or cratered but retain a generally consistent profile. Relumed plots are often slightly larger, uneven in shape, or off-center within their housing.
• Crazing: Original aged tritium frequently develops micro-crazing, a fine network of surface cracks in the lume material, as the phosphor compound dries and shrinks over decades. This crazing is a sign of genuine age and cannot be easily replicated. Fresh relume shows no crazing; the surface is smooth and continuous.
• Adhesion: Original factory lume is flush with or very slightly proud of the surrounding dial surface. Relumed plots may appear slightly mounded, show small air bubbles, or have uneven adhesion at the edges under magnification.

Case authentication

The five-zone finishing described in the construction section above is the primary case authentication tool. Beyond finishing assessment, the following checks apply:

Feature	Correct (unpolished)	Over-polished
Top surface	Radial sunray striations, fine and directional	Uniform mirror or buff, no striations
Chamfer edge	Sharp 90-degree break	Softened, rounded gradient
Case sides	Straight longitudinal brushing	Mirror polish or swirl marks
Lug corners	Sharp, defined angles	Rounded, loss of definition
Polished chamfer	Flat mirror surface	Convex/rounded from wheel buffing

Unpolished cases are perhaps the single largest differentiator at the premium end of the 145.014 market, adding 30-50% over an equally dialed example in a polished case. The concept of “coherence,” where all components feel as if they have lived one life together, commands the strongest premiums, exactly as with vintage Rolex sport references.

Bracelet authentication

The 1171/633 Moonwatch bracelet is not correct for the Mark II; its 633 endlinks will not nestle flush into the hooded lugs, creating a visible gap at the case/bracelet transition. For the 1162/173, the standard stretch assessment applies: lay the bracelet flat, bend to maximum natural arc, and assess the radius of curvature. Light to moderate stretch is expected after 50+ years. Excessive stretch where individual links rock visibly or where length has grown by 10mm+ indicates significant wear. Worn pins can be replaced; stretched link bodies cannot be fully corrected.

Modern Omega service replacement 1162/173 bracelets are identifiable by screw heads visible on link undersides (original vintage bracelets use friction-fit pins). A service bracelet is a genuine Omega part but not period-correct vintage. Its presence is a low-severity authenticity issue.

Common frankenwatch configurations

The 145.014’s relative affordability and the racing dial premium create specific incentive structures for parts assembly. The five most common configurations documented in the collector community:

Type A: Black-to-racing dial swap. The most prevalent and financially motivated configuration. A standard black-dial 145.014 case and movement are combined with a grey racing dial, dramatically increasing apparent value. Detection: lume aging mismatch between the replacement racing dial and the original hands/case; racing dial text print quality inconsistent with period production; orange hands sourced from incorrect Seamaster chronograph donors; missing “T SWISS MADE T.” This is the configuration to be most vigilant about. The single most reliable confirmation is an Omega Extract of Archives (approximately CHF 120), which matches the movement serial to the case reference and original shipping destination.

Type B: Wrong hands on correct dial. A correct racing dial with incorrect hands. Detection: lume mismatch (hands aged differently from dial); orange hour/minute hands (never factory correct); dimensions inconsistent with the 13.5mm Mark II minute hand specification; wrong hand profile. Fully orange hour and minute hands from Seamaster chronograph donors are the most common incorrect substitution.

Type C: Stripped 145.034 case. The 145.034 gold-plated Mark II shares the same case architecture. A documented configuration involves a 145.034 case stripped of plating and fitted with a 145.014 caseback. Detection: inspect case metal under magnification for irregular color beneath the stainless appearance; verify caseback engravings match the case.

Type D: Movement transplant between 145.022 and 145.014. The cal. 861 is physically the same movement in both references. Movements can be transplanted between cases with no physical modification. Detection: movement serial should correspond to the 145.014 production era (27,xxx,xxx to 33,xxx,xxx); caseback interior should read “145.014”; an Extract of Archives confirms the original pairing.

Type E: Cal. 1861 service replacement. The cal. 1861 physically fits the 145.014 case, and Omega service centers may have fitted 1861 movements as replacements after the mid-1990s. Detection: unmistakable silver/rhodium plating visible upon caseback removal. This represents a non-original movement that reduces both collector value and historical authenticity, but it is genuine Omega service work, not fraud.

Configuration	Detection method	Severity
Racing dial on black-dial case (dial swap)	Lume mismatch; wrong hands; missing T SWISS MADE T	High
Orange hour/minute hands (Seamaster donor)	Wrong profile; fully orange instead of correct mixed scheme	High
145.022 Moonwatch hands (too long)	Minute hand overhangs subdial rings by ~0.5mm	Medium
Stripped 145.034 case	Irregular metal color under magnification; caseback mismatch	High
Cross-reference movement transplant (145.022)	Serial outside 145.014 production range; verify via Extract	Medium-High
Cal. 1861 service replacement	Rhodium/silver plating on movement bridges	Medium
Modern 1162/173 bracelet (screw-link)	Screw heads on link undersides; newer finish	Low
1171/633 Moonwatch bracelet	Endlinks will not nest flush into hooded lugs; visible gap	Medium

Market positioning and pricing

The premium structure

The pricing hierarchy within the 145.014 is driven by two primary factors: dial variant and case condition. The racing dial commands approximately 20-35% over an equivalent standard black dial in comparable condition. Unpolished cases add 30-50% or more at the upper end. The gold-plated 145.034, despite being objectively rarer, paradoxically sits at the bottom of the hierarchy due to reduced collector appetite for gold-plated pieces.

The racing dial premium is driven by structural scarcity (approximately 150 units produced, roughly 1-3% of total production), visual distinction within the Speedmaster family, and the most dramatic value asymmetry in the vintage Speedmaster market: the same racing aesthetic on a 145.022-69 Moonwatch commands $50,000-$70,000, while the 145.014 racing dial trades at approximately 1/15th that price for the same movement and the same dial character. This disparity is the central “value thesis” cited by every major publication covering the reference.

Current market pricing by variant and condition

Condition	Standard black dial (USD)	Racing/exotic dial (USD)
Poor (heavy polishing, replaced parts, non-working)	$400 – $900	$800 – $1,500
Average/Fair (visible wear, may need service)	$1,000 – $1,800	$1,800 – $2,600
Good (complete, correct, honest wear, working)	$2,000 – $2,800	$2,800 – $3,800
Excellent (minimal wear, original finishing, serviced)	$3,000 – $4,000	$3,800 – $5,500
Exceptional/NOS-like (near-mint, unpolished, outstanding patina)	$4,500 – $5,500+	$5,500 – $7,000+

Full-set premium (box, papers, bracelet): +30-60% over watch-only prices. Full-set examples are extremely rare given 50+ years of age. A full-set example at approximately $7,000 represents the current upper ceiling.

2025 auction results

Twelve realized auction sales from 2025 provide a useful pricing floor, as auction results typically represent the lower end of the market relative to dealer pricing. The range runs $1,447-$3,903 with a median around $2,660.

The 145.014 price trajectory has been less volatile than modern Omega references because its values are set by organic collector demand rather than MSRP arbitrage. The correction from COVID-era peaks has been moderate, roughly 10-20%, with current prices stabilizing in a band consistent with the pre-COVID growth trend. Over the longer term, the watch demonstrated steady, gradual appreciation: from $700-$1,100 in the early 2010s to a $2,000-$4,000 core range today, representing 2-4x appreciation over 10-12 years.

Chrono24 market data shows a sustained price increase beginning 2014-2015 that correlates directly with the modern reissue announcement. The re-edition introduced the design to new buyers and established a retail ceiling ($6,250) that made vintage examples appear attractively priced. The modern reissue has subsequently been discontinued, removing the new-purchase alternative and further supporting vintage appreciation.

Rarity and survival rates

Omega has never disclosed production figures. Collector consensus places total production in the low thousands to low tens of thousands. For the racing dial, approximately 150 units were produced. The standard black dial is described as “relatively common” by Fratello, with roughly 89 listings on Chrono24 at any given time. The racing dial is “increasingly rare to find,” and a meaningful fraction of available racing dial listings are suspected dial swaps, further reducing authentic supply.

Condition preservation is uneven. The 145.014 was historically undervalued, which meant many examples were worn daily without collector-level care and sent through polishing services that destroyed the distinctive sunburst case finishing. Unpolished examples with original finishing are notably harder to source than the raw number of available watches would suggest.

Demand drivers and outlook

Demand is growing, driven by several structural tailwinds. As 145.022 Moonwatches from the late 1960s and early 1970s have appreciated beyond $4,000-$6,000, collector attention cascades to affordable alternatives with identical movements. The broader market appetite for exotic dial variants (tropical, panda, racing) has specifically elevated the racing variant. Fratello, HODINKEE, Chrono24 Magazine, and Oracle Time have all produced positive features since 2016. The discontinuation of the 2014 re-edition removed the new-purchase alternative, further supporting vintage values.

The greatest asymmetric opportunity remains the racing dial. At $3,000-$4,500 versus $50,000+ for its Moonwatch equivalent, any increased institutional attention on Speedmaster racing dials broadly could compress this gap meaningfully. Collector Jun Cajayon articulated the prevailing view: “I still consider the current market price of the Mark II as well as the whole Mark series to still be below their actual value. Considering its shorter production period and the fact that a similar-year model Speedmaster 145.022 would be significantly more expensive in the market proves this point.”

Wearability and collector standing

Case size and modern wearability

The 42mm case with a 45mm lug-to-lug sits compactly on the wrist, more so than the numbers suggest. The hooded/integrated lug design pulls the case footprint inward, producing a shorter, tighter wrist impression than a 42mm watch with conventional protruding lugs. For reference, the modern Speedmaster Moonwatch 3861 measures approximately 47mm lug-to-lug at the same 42mm diameter. Fratello’s Michael Stockton observed that the “short lugs” provide “a perfect fit on my tiny wrist,” confirming the design suits smaller wrists better than many 42mm competitors.

At 14-15mm thick, the Mark II is approximately 1mm thicker than the Moonwatch. This difference is subjectively more significant than it sounds. The Moonwatch’s thickness is broken up by the case, bezel, and domed crystal, creating visual relief. The Mark II’s thickness reads as monolithic: its flat mineral crystal and lack of a protruding bezel offer no visual stepping. One Omega Forums owner described looking down at it as resembling “the Campbell’s Soup aisle.” This is not a dress watch and will not slide under a standard shirt cuff.

Daily comfort, however, is generally reported as good. The short lug-to-lug allows the watch to conform to the wrist naturally, and the recessed crown and pushers eliminate snag points. The 1162 bracelet is widely praised as one of the most comfortable bracelets Omega has ever made.

Strap options

The 20mm lug width accepts any 20mm strap, but the hooded lug architecture creates practical complications for NATO straps, which require curved spring bars and tight threading. Fratello describes this as a “nightmare” for NATO fans. Leather rally straps are the most commonly recommended non-bracelet option. The Moonwatch, by contrast, is famously a “strap monster.”

Water resistance and daily use

Factory-rated to 120m/10 ATM, the Mark II had superior water resistance to the Moonwatch’s 50m, a direct benefit of the tonneau case construction, flush crystal, and screw-down caseback. On a 50+ year old, unserviced example, that rating should be treated as decorative. Rubber gaskets degrade through UV exposure, thermal cycling, chemical contact, mechanical compression from pusher operation, and simple age. The pushers are the weakest point: each actuation flexes the crown tube gaskets and pusher seals.

After full service with new gaskets and pressure testing, brief splashes during handwashing are acceptable. Intentional submersion, showering, or swimming should be avoided.

Crystal durability

The mineral glass crystal is harder and more scratch-resistant than the Moonwatch’s Hesalite for daily use, and the internal tachymeter is fully protected from surface wear. However, mineral glass is more brittle under impact: it will crack or shatter from a sharp blow, whereas Hesalite flexes and dents. Hesalite scratches can be buffed out with PolyWatch; mineral glass scratches require crystal replacement.

Collector standing

Within the Speedmaster family, the Mark II sits directly below the Moonwatch in prestige and well above the subsequent Mark III through Mark V in purist esteem. It represents an approximate 40-60% discount to a comparable 145.022 for an equivalent-era example with identical movement. The structural factors maintaining this discount: no NASA mission association (NASA rejected the Mark II for testing), the tonneau case considered less “timeless” by many collectors than the round Moonwatch, lower profile in major auction catalogs, and a less structured collecting community (no sub-reference distinctions comparable to the 145.022-69, -71, -74 series that generate specialized collecting within the Moonwatch universe).

Position among 1970s sport chronographs

The Mark II competes for collector attention with several iconic 1970s chronographs, nearly all of which command higher prices driven by stronger cultural narratives. The Mark II’s competitive advantage is value: cal. 861 in a distinctive short-production case at accessible prices, with credible engineering lineage.

Entry-level Speedmaster collectors often aspire to own a Moonwatch and treat the Mark II as an intriguing alternative or companion once they begin exploring the broader catalog. Seasoned Speedmaster enthusiasts increasingly treat the 145.014 as a value play anchored by shared mechanical DNA. Sentiment has shifted from “overlooked tool watch” to “underpriced relative” over the past decade, and the fundamental scarcity of clean, unpolished, original-dial examples is structurally supportive of long-term value.

The succession: reference 176.002 and beyond

The Mark II was succeeded by the Mark III (reference 176.002), introduced in 1971 while the Mark II was still in production. The Mark III represented a more dramatic step forward: it was the first Speedmaster to use an automatic movement (caliber 1040, derived from a joint Omega-Lemania development) and was produced in three distinct case variants. The transition involved not just a case change but a fundamental shift in movement architecture, from manual-wind to self-winding.

The Mark IV followed in 1973 with modular inner-case construction (where the movement, dial, and crystal could be removed as a single unit), the Mark 4.5 extended the series through the early 1980s using the Lemania 5100-based caliber 1045, and the Mark V appeared briefly in 1984 for the German market only (approximately 40,000 pieces, nicknamed “Teutonic”).

After the Mark V, Omega did not produce another Mark-series Speedmaster for three decades. The 2014 re-edition (references 327.10.43.50.01.001 and 327.10.43.50.06.001) used the automatic Co-Axial caliber 3330 in a case closely modeled on the original 145.014. The re-edition retailed for $6,250, establishing a price ceiling that made vintage originals look attractively priced and contributing to the sustained appreciation beginning in 2014-2015. The modern re-edition has subsequently been discontinued, removing the new-purchase alternative.

Throughout this entire evolution, the standard Speedmaster Professional Moonwatch remained in continuous production, outlasting every Mark-series variant. The 145.014 was the last hand-wound Speedmaster Professional in a tonneau case. Every subsequent Mark used an automatic movement, and every subsequent hand-wound Speedmaster Professional returned to the traditional round case. This makes the 145.014 an unrepeatable configuration in the Omega catalog.
