Wittnauer Professional Chronograph 6002/5

The Wittnauer Professional Chronograph reference 6002/5 stands as one of the most compelling value propositions in vintage chronograph collecting. Powered by the legendary Valjoux 72 movement, the same caliber found in the Rolex Pre-Daytona reference 6234 and Heuer Carrera 2447, this mid-century chronograph delivers impeccable horological pedigree at a fraction of the cost of its more celebrated contemporaries. The 6002/5 occupies a fascinating position in watchmaking history, representing Wittnauer’s efforts to compete in the premium sports chronograph market during the golden age of mechanical timekeeping. With its distinctive tri-color dial, crisp geometric case architecture, and robust construction, the 6002/5 embodies the essential characteristics collectors prize in vintage chronographs: legibility, functionality, and timeless design.​

What makes the 6002/5 particularly intriguing is its connection to a pivotal moment in horological history. While it was Wittnauer’s larger 242T that famously competed in NASA’s rigorous testing program to select the official moon watch in 1965, the 6002/5 shares the same design DNA, movement platform, and manufacturing period. This watch represents Wittnauer at the height of its capabilities, before the brand’s eventual decline and acquisition by Bulova in 2001.​​

History & Production Period

The Wittnauer 6002/5 emerged during the early 1960s, a period when the Wittnauer Watch Company was operating under the ownership of the Longines-Wittnauer Watch Company (established 1936). This era represented the zenith of American-Swiss watchmaking collaboration, with Wittnauer serving as the vehicle through which Longines could access the American market without the heavy import taxes that burdened purely Swiss imports.​

Production of the 6002/5 began around 1960 and continued through the late 1960s, though precise production records remain elusive. The watch was positioned as a professional-grade tool watch, marketed alongside Wittnauer’s other chronographs in the Professional line. This family included the larger 242T (38mm), the dive-oriented 7004/7004A (40mm), and various other specialized chronographs that established Wittnauer’s reputation for robust, functional timepieces.​

The reference nomenclature can be confusing for collectors: 6002/5 appears to be the official reference number, while 235T is the case number stamped on examples. Some early examples feature dials marked simply “Wittnauer” without the “Professional Chronograph” text, these so-called “pre-professional” dials are considered particularly desirable by collectors. Later production incorporated the full “Professional Chronograph” designation as Wittnauer standardized its product line branding.​

Production quantities are unknown, but the 6002/5 appears less frequently in the market than the larger 242T or 7004 models, suggesting more modest production numbers. The watch competed directly with chronographs from Breitling, Gallet, and other mid-tier Swiss manufacturers of the period, offering similar specifications and quality at competitive pricing.​

The 36mm diameter positions the 6002/5 as comparable in size to the Heuer Carrera 2447 and smaller than the Rolex Pre-Daytona (which measured 36-37mm depending on variant). This sizing wears extremely well on modern wrists, offering vintage charm without sacrificing wearability. The beveled lugs are a signature Wittnauer design element, featuring crisp geometric facets that catch light beautifully and distinguish the watch from competitors.​

Movements/Calibers

The Wittnauer 6002/5 houses the Valjoux 72, one of the most celebrated chronograph movements in horological history. Wittnauer marked this movement as caliber 13W in their documentation.​

Wittnauer Professional Triple Register Valjoux 72  

Valjoux 72 Specifications:

• Type: Manual-winding chronograph​
• Diameter: 29.50 mm (13 lignes)​
• Height: 6.95 mm​
• Jewels: 17​
• Frequency: 18,000 vibrations per hour (2.5 Hz)​
• Power Reserve: 48 hours​
• Chronograph Architecture: Column wheel with lateral clutch​

Complications and Functions:

• Central hours and minutes
• Central chronograph seconds hand
• Running small seconds at 9 o’clock
• 30-minute chronograph counter at 3 o’clock
• 12-hour chronograph counter at 6 o’clock​

The Valjoux 72 represents the pinnacle of mid-century chronograph development. Introduced in 1938 as an evolution of the Valjoux 23, the caliber added a 12-hour totalizer to create the classic three-register layout that has become synonymous with vintage chronographs. The movement’s column wheel construction provides smooth, refined pusher action and precise chronograph function. This same caliber powered some of the most iconic chronographs ever made, including early Rolex Daytonas (pre-1988), Heuer Carreras, Breitling Premiers, and Patek Philippe references.​

Production of the Valjoux 72 continued from 1938 through 1974, after which the frequency was increased to 21,600 vph in some applications. The examples found in 6002/5 watches maintain the original 18,000 vph beat rate, which is correct for the 1960s production period.​

Movement finishing is functional rather than decorative. The caliber features rhodium plating, basic perlage on the main plate, and industrial-grade anglage on bridges. The movement is signed “Wittnauer” rather than “Valjoux,” a common practice among brands using ébauche movements. Serial numbers appear on the movement, though comprehensive dating records are not publicly available.​

Dial Variations

The 6002/5 is most commonly encountered with a tri-color dial configuration that has become its signature aesthetic. However, several variations exist that significantly impact desirability and value.

Standard Tri-Color Dial (Most Common):

• Base color: White to cream (often aged to warm ivory patina)​
• Tachymeter scale: Blue outer ring​
• Telemeter scale: Red inner markings​
• Subdial rings: Applied, slightly recessed​
• Indexes: Applied Arabic numerals with luminous material​
• Text: “Wittnauer” at 12 o’clock, “Professional Chronograph” below (on later examples)​

Pre-Professional Dial Variant:

• Earlier production examples feature dials marked only “Wittnauer” without the “Professional Chronograph” designation​
• These single-line dials are considered more desirable by some collectors due to their cleaner aesthetic and earlier production period​
• All other dial elements remain consistent with standard production​

Dial Aging and Patina:

• Original white dials typically age to a warm cream, ivory, or champagne tone​
• This patina is highly desirable and should show even coloration across the dial surface​
• Some examples exhibit darker spotting or tropical characteristics, particularly around the edges​
• The tri-color printing (black, blue, red) should remain crisp and vibrant​

Hands:

• Hour and minute hands: Arrow-shaped (often called “dauphine” or “alpha” style) with luminous fill​
• Chronograph hand: Blued steel with straight baton design​

• Subdial hands: Blued steel batons​
• The steel hands develop a distinctive blue patina that collectors prize​

Luminous Material:

• Original examples feature tritium lume on both dial indexes and hands​
• Period-correct tritium ages to a warm beige, yellow-orange, or amber tone​
• Lume should exhibit consistent aging across dial and hands​
• Well-preserved examples retain intact lume plots without degradation or crumbling​
• “T Swiss T” marking at 6 o’clock position indicates tritium lume (found on some examples)​

Dial condition is paramount when evaluating a 6002/5. Original, unrestored dials with intact printing and matching lume patina command significant premiums over refinished examples.​

Case & Bezel Variations

The 6002/5 was produced exclusively in stainless steel with consistent design elements throughout its production run. Unlike some contemporary chronographs that appeared in multiple materials or case designs, Wittnauer maintained a unified aesthetic for this reference.

Case Design:

• Two-piece construction with screw-down caseback​
• Highly polished finish throughout​
• Distinctive beveled lugs with sharp geometric facets​
• The lug design features crisp bevels that create light-catching surfaces, a signature Wittnauer styling element​
• Triangular lug profile similar to contemporary Heuer Autavias and Breitling chronographs​

Case Numbers:

• Most examples are stamped “235T” on the case​
• This case number appears separately from the reference number 6002/5​
• Understanding the relationship between these numbers is important for authentication​

Bezel:

• Smooth, polished stainless steel throughout production​
• No rotating bezel functionality​
• Meets a heavily domed acrylic crystal​

Caseback:

• Screw-down design for improved water resistance​
• Most examples feature minimal engraving, typically just “Stainless Steel” marking​
• Some examples have clean, unmarked casebacks​
• Casebacks often show minor scratches and wear from tool marks during servicing​

Crown and Pushers:

• Crown: Large, signed with Wittnauer logo​
• Original signed crowns are an important authentication point​
• Pushers: Round pump-style design​
• Pushers are not signed​
• Some examples feature replacement crowns (often Heuer-signed) from period servicing​

The geometric beveling of the lugs is perhaps the most distinctive case feature. These facets should remain crisp and well-defined on unpolished examples. Over-polished cases lose these bevels, resulting in rounded, softened lugs that diminish the watch’s visual impact and value.​

Bracelet & Strap Options

Period-correct bracelet options significantly enhance the 6002/5’s authenticity and value, though finding original examples in good condition presents challenges.

FS: Wittnauer 242T 235T 7004 Kestenmade Beads of Rice bracelet 

Original Wittnauer Beads of Rice Bracelet:

• Construction: Folded link “beads of rice” style​
• Material: Stainless steel​
• Clasp: Folding clasp with raised Wittnauer logo​
• Lug width: 18mm end links​
• This bracelet style was shared across multiple Wittnauer Professional chronograph references, including the 235T, 242T, and 7004​

Bracelet Condition Considerations:

• Period beads of rice bracelets typically exhibit significant stretch due to the folded link construction​
• Stretched bracelets may fit only smaller wrists (often 7 inches or less)​
• The raised Wittnauer logo on the clasp is a key authentication marker​
• Original examples with minimal stretch are extremely rare and valuable​

Alternative Period Bracelets:

• Some examples left the factory on unsigned “rice beaded” style bracelets without Wittnauer markings​
• Generic beads of rice bracelets were common period accessories​

Leather Straps:

• Most surviving examples are found on replacement leather straps​
• Period advertising suggests leather was an accepted pairing​
• Modern collectors often pair the watch with vintage-style leather, racing straps, or handmade artisan straps​

Finding an original Wittnauer-signed beads of rice bracelet in wearable condition is challenging. New old stock (NOS) examples occasionally surface from specialty dealers but command premium prices. Collectors should verify authenticity through the signed clasp and appropriate end link sizing (18mm for the 6002/5).​

Identifying Original vs. Replaced Parts

Authentication and originality assessment are critical when evaluating vintage Wittnauer chronographs. The relative obscurity of the brand compared to Rolex or Omega means less comprehensive documentation exists, requiring collectors to develop keen observational skills.

Dial Authenticity:

• Original dials exhibit printing quality consistent with 1960s Swiss standards: crisp, even, with no blurring​
• The tri-color printing (black, blue, red) should show consistent ink quality and registration​
• Luminous material on indexes should match the lume in the hands in terms of color and aging patina​
• Reprinted or refinished dials often show telltale signs: fuzzy printing, incorrect font weights, misaligned elements, or modern luminova instead of aged tritium​
• The “Professional Chronograph” text should be properly positioned and scaled; some refinishers get this wrong​
• Dial feet attachment points should be correctly positioned when viewing the movement side​

Hand Originality:

• Original hands feature tritium lume that ages to warm beige, yellow, or amber tones matching the dial indexes​
• Relumed hands are common and often poorly executed, showing bright modern lume or green afterglow under UV light​
• The blued steel chronograph and subdial hands should exhibit natural aging and patina, not fresh bright blue​

Wittnauer Chronograph 6002 Vintage mens Watch 

• Hand shapes and proportions should be correct: arrow/alpha style for time hands, straight batons for chronograph hands​

Movement Verification:

• The movement should be signed “Wittnauer” with caliber designation “13W”​
• Valjoux 72 movements are relatively common, so verify all components match period-correct specifications​
• Check for proper Wittnauer branding on the rotor and bridges​
• Service replacements of individual movement components are acceptable if performed properly​

Crown and Pusher Originality:

• The crown should bear the Wittnauer logo​
• Unsigned crowns or crowns from other manufacturers (commonly Heuer) indicate replacement​
• While replacement crowns are common due to loss or damage during servicing, original signed crowns are strongly preferred​
• Pushers should be round pump-style without signatures​

Case Condition and Polishing:

• The hallmark beveled lugs should retain sharp, crisp facets​
• Over-polished cases show rounded, softened edges and loss of geometric definition​
• Some polishing is acceptable and expected on 60-year-old watches, but excessive material removal damages value​
• Original brushed surfaces on caseback should be preserved where possible​

Crystal:

• Original crystals are acrylic (plexiglass) with a pronounced dome​
• Replacement acrylic crystals are acceptable and often necessary due to damage​
• Sapphire crystal replacements are incorrect for this reference and considered inappropriate modifications​

The Wittnauer collecting community generally accepts that some service replacements are inevitable given the age of these watches. However, the core components (dial, hands, case) should remain original and unrestored for maximum value and collectibility. When in doubt, consult with experienced Wittnauer collectors or vintage watch specialists, as the brand’s relative obscurity means fewer authentication resources exist compared to more mainstream marques.​
