Omega Constellation 168.012

The Omega Constellation reference 168.012 was produced primarily around circa 1970. This model is significant as a prime example of the “C-Shape” Constellation, a design conceived by the renowned Gérald Genta, which marked a modern evolution for Omega’s flagship chronometer line. Introduced in 1964, the C-Shape era lasted until approximately 1978, and the 168.012 embodies this period’s blend of streamlined aesthetics with Omega’s traditional commitment to precision and luxury. It represents a shift from the earlier “Pie-Pan” designs towards a cleaner, more contemporary look, often featuring the reliable Caliber 564 movement.

Key Details and Variations

Variations:

• Dial Variations:
  • Linen Texture: A distinctive and popular option, often in slate grey or silver, providing a fine cross-hatched pattern that adds depth.  
  • Solid Gold Dials: Found in 18K gold case versions, sometimes featuring diamond-set hour markers.  
  • Other Finishes: Standard smooth or sunburst finishes in colors like silver, grey, and gold were also available.  
• Case Material Variations:
  • Stainless Steel: The most common and widely available version.  
  • Solid 18K Gold: Primarily yellow gold, offering a more luxurious option.  
  • Gold-Capped: While not as explicitly documented for the 168.012 as for other C-Shapes like the 168.017 or 168.029, gold-capped versions (gold layer over steel) were a common Omega offering and are plausible for this reference.  
• Movement: The primary movement is the Omega Caliber 564. There is no strong evidence in the provided snippets of other calibers being factory-fitted to the 168.012 reference, though the broader C-Shape line used other calibers like the 561 (date, non-quickset) and 751 (day-date) in different references.  

Correct Dial:

• Original dials feature applied Omega ‘Ω’ logo and an applied Constellation star (usually above 6 o’clock).  
• Text includes “OMEGA,” “AUTOMATIC,” “CHRONOMETER OFFICIALLY CERTIFIED,” and “CONSTELLATION”.  
• Hour markers are applied batons, sometimes with black enamel/onyx inlays or tritium lume plots at their outer edges.  
• A framed date window is present at 3 o’clock.  
• Original dial finish (e.g., linen, sunburst) is crucial for value; refinished dials are less desirable.

Correct Hands:

• Typically “stick” or “baton” style hands, matching the material of the case and markers (steel or gold).  
• Often feature a central channel filled with black paint or tritium luminous material for legibility.  

Correct Case:

• Distinctive “C-Shape” profile with integrated, flowing lugs, a Gérald Genta design.  
• Typically 35mm in diameter.  
• Screw-down caseback featuring the Constellation Observatory medallion with eight stars. The preservation of this medallion is a key condition indicator.  

Correct Crystal:

• Originally fitted with a Plexiglass (acrylic) crystal.  
• Authentic Omega crystals often have a tiny, embossed Omega ‘Ω’ logo in the center, visible under magnification.  

Correct Crown:

• Signed Omega crown.  
• For C-Shape Constellations, this was often a decagonal (10-sided) or a distinct fluted round shape, designed to complement the case aesthetics.  

Additional Details

Market Value & Desirability: The Omega Constellation 168.012 is a collectible vintage watch. Its value is influenced by several factors:

• Condition: Case sharpness (unpolished preferred), dial originality and preservation (linen dials are particularly sought after), and movement functionality are paramount.  
• Originality: Presence of original crown, crystal (with Omega logo), and period-correct bracelet significantly enhances value.  
• Case Material: Solid gold versions command higher prices than stainless steel.  
• Bracelet: Original Omega bracelets, such as the No. 11 / Ref. 1040 “brick-link” style (often with 518 end links) or “Beads of Rice” styles compatible with the 19mm lug width, add to desirability and value. Note that bracelets could be later, period-correct Omega replacements.  
• Genta Design: The “C-Shape” case designed by Gérald Genta adds a significant layer of collector appeal, linking it to one of horology’s most influential designers.  

Production & Evolution (C-Shape Context): The reference 168.012 is a product of the “C-Shape” era of Omega Constellations, which began in 1964 and lasted until about 1978. This design, attributed to Gérald Genta, represented a modernization of the Constellation line, moving towards sleeker, integrated case designs. The C-Shape was a significant departure from the earlier “Pie-Pan” Constellations and co-existed with them for a period. The 168.012, typically housing the Caliber 564 with its quickset date, is a refined example from this era. It shares design characteristics with other C-Shape references like the 168.017 (date, Cal. 564), 168.019 (day-date, Cal. 751), and later 168.0056 (date, Cal. 1011). The C-Shape’s longevity and adaptability, housing various movement updates and dial styles over 14 years, underscore the strength of Genta’s original concept.
