Omega Seamaster 2767

The Omega Seamaster reference 2767 is a vintage timepiece from the early 1950s, typically produced between 1952 and 1954, though some movement serials suggest slightly broader dating. It is a classic representation of the early Seamaster line, which evolved from Omega’s experience producing waterproof watches for the British military during WWII. The 2767 is most commonly associated with Omega’s “bumper” automatic movements, particularly the Caliber 354 and Caliber 351. This reference is characterized by its robust case design, often featuring “wide” or “beefy” lugs, and was offered in various materials including stainless steel, gold-capped, and solid gold. Dial variations are numerous, with silver, gold/champagne, and rare black dials, sometimes featuring a sought-after “honeycomb” or “waffle” texture. The “SC” suffix often found in sub-references like 2767-1SC most likely denotes “Seconde Centrale” (Central Second).  

Specifications

Key Details & Variations

Variations

The Omega Seamaster 2767 is a diverse reference family:

• Reference Suffixes & Prefixes:
  • SC: Most likely denotes “Seconde Centrale” (Central Second). Numerical suffixes (e.g., -1, -2, -3) indicate specific iterations or minor design changes.  
  • KO: Indicates a gold-capped case over stainless steel.  
  • CK: Generally signifies a stainless steel case.  
• Case Materials: Stainless steel, gold-capped (often 14K or 80-micron gold plate over steel), solid gold (typically 18K), and some steel and gold two-tone models.  
• Dial Designs:
  • Colors: Silver, gold/champagne, rare black, and bi-tone (“tuxedo”) dials.  
  • Textures: Highly desirable “honeycomb” or “waffle” textures, as well as smooth finishes.  
  • Indices: Applied dart, arrowhead, or “epi” shaped hour markers. Arabic numerals often at 12, 3, 6, and 9.  
• Case Backs: Both snap-on (press-in) and screw-in (twist back) case backs were used, varying by sub-reference. “WATERPROOF” engravings are found on some, typically screw-back versions.  
• Chronometer Versions: Some Seamaster 2767 models, particularly those with the Caliber 354, were officially certified chronometers and marked accordingly on the dial.  

Correct Dial

• Markings: Signed “Omega,” “Automatic,” and “Seamaster.” Chronometer versions will add “CHRONOMETRE” and often “OFFICIALLY CERTIFIED”. “Swiss Made” is usually at the 6 o’clock position.  
• “Seamaster” Script: Early 1950s script style, sometimes with a more flowing “S”.  
• Omega Logo: Applied metal Ω logo, sharply defined.  
• Lume: Original Radium lume on hands and often as dots with hour markers, which patinates over time.  

Correct Hands

• Style: Typically Dauphine hands, often with Radium luminous fill.  
• Material usually matches the hour markers and case accents.

Correct Case

• Shape and Dimensions: Generally 34mm-34.5mm diameter (excluding crown), lug-to-lug around 42mm, thickness approx. 10-11mm.  
• Lugs: Known for distinctive “wide,” “beefy,” or “oversized downturned” lugs, contributing to a substantial wrist presence. Some suggest these prefigure the “Lyre” lugs.  
• Crown: Original Omega-signed crown, with period-correct styles like “clover-leaf” or “flat foot”.  
• Internal Markings: Inside case back should have Omega Watch Co. markings, “Fab. Suisse,” “Swiss Made,” full reference number (e.g., 2767-3 SC), and material indication (e.g., “Acier Inoxydable” or gold hallmarks). Case maker marks (e.g., CB, HF) may be present.  

Additional Details

The Seamaster 2767 primarily used Omega’s 35x series of “bumper” automatic movements:

• Caliber 354: 17 jewels, 19,800 vph, ~42-hour power reserve, Incabloc shock protection. Often chronometer-certified. Produced 1952-1955.  
• Caliber 351: 17 jewels, 19,800 vph, ~42-hour power reserve. Produced 1949-1952.  
• Caliber 352: 17 jewels, 19,800 vph, ~42-hour power reserve, Incabloc, chronometer with excenter regulator. Produced 1949-1952.  
• Mechanism: The rotor swings in a limited arc, “bumping” off buffer springs to wind the mainspring, creating a unique tactile sensation.  

Original crystals were acrylic (Plexiglass), often with a tiny, centrally etched Omega logo.  

• Omega “Beads-of-Rice” (BoR) Bracelet: Highly desirable and significantly increases value, especially if matching the case material.  
• Leather Straps: Common original fitment, paired with an Omega-signed buckle.  

The Seamaster 2767 is a well-regarded vintage Omega, offering good value for its quality and history.

• Value Factors: Condition (unpolished case, original dial), originality of all parts, dial rarity (black, honeycomb), case material (solid gold > gold-capped > steel), presence of original BoR bracelet, and chronometer certification are key drivers.  
• Price Range: Stainless steel models typically range from $800-$1,700 USD. Rare configurations can command significantly more.  
• Dial: Check for crisp printing, correct “Seamaster” script and Omega logo style for the 1950s, and consistent aging of original Radium lume.  
• Case Markings: Verify internal case back engravings (Omega name, reference, material, Swiss hallmarks for gold) and any external markings (Seamaster logo, “WATERPROOF”).  
• Movement: Confirm correct Omega bumper caliber (351, 352, or 354), signatures, copper-colored plating, and period-appropriate serial number.  
• Crown & Crystal: Look for original Omega-signed crown and potentially a signed crystal.  
• Bumper Movements: Require experienced watchmakers familiar with vintage Omega bumper mechanisms. Buffer springs are a common wear point. Parts are generally available but specialized knowledge is key.  
• Water Resistance: Original 30m rating (for some variants) should not be trusted today. Keep vintage watches dry.  
• Radium Lume: Handle with care, especially during servicing, due to the radioactive nature of radium.
