The Omega Constellation C-Case emerged in the late 1960s, marking a design shift from the earlier pie-pan models to a streamlined, integrated silhouette that Gerald Genta helped pioneer. Its monocoque “C-shaped” case and distinctive dial furniture set it apart in Omega’s lineup, while the Constellation’s chronometer pedigree ensures it’s prized by collectors looking for both style and substance from the golden era of Swiss watchmaking.

Reference numbers like 168.017 (date) and 168.027 (day-date) define the main variants, each housing the revered caliber 564 or 751 automatic movements, celebrated for their accuracy and smooth quickset date function. The 35mm case wears slightly larger due to its tonneau shape, and dials range from linen-textured to sunburst silver, with applied markers and the iconic star above 6 o’clock. Collectors value original dials and sharp case lines; heavy polishing or replaced crowns can affect desirability.

Price variation is driven mainly by dial condition, movement service history, and originality. The integrated bracelet versions command a premium, while well-preserved leather strap models offer value. Lume plots and hands should match, and the medallion on the caseback—featuring the Geneva Observatory—should be crisp. This model is a strong choice for those seeking a vintage Omega with both technical heritage and distinctive 1970s style.

What owners love

  • The integrated case and bracelet design stands out for its unique mid-century look, which is instantly recognizable and sets it apart from other vintage Omegas.
  • Owners consistently praise the accuracy and reliability of the caliber 564 and caliber 751 automatic movements found in these models.
  • The flat, slim case profile makes it exceptionally comfortable to wear under a cuff and gives it a refined, elegant wrist presence uncommon among vintage watches of the era.

Common Criticisms

  • The case design is highly prone to over-polishing, making it difficult to find examples with crisp original edges and finishing.
  • Many note that the original bracelets and end links can be difficult or expensive to source if missing or damaged.
  • The small 35mm size feels undersized to some, especially compared to modern standards, which can limit its appeal for those with larger wrists.
