If you want a vintage Omega Constellation that slips under a shirt cuff and still carries a chronometer certificate, the ref. 167.021 is the one to look at. Introduced in 1966, it was Omega's ultra-thin answer within the Constellation line, and this example dates to that first year of production.

The 33mm yellow gold-capped case is only 7.7mm thick. The steel screw-in caseback carries the gold Observatory medallion that marks every Constellation of the period. On the wrist it wears larger than the number suggests, thanks to the slim bezel and broad dial. The dial is silver with a sunburst finish, applied gold markers with black inlays, and matching gold hands.

Inside is the Calibre 712, the thinnest automatic chronometer movement Omega ever produced. Developed for Omega by Piguet and Rayville within the SSIH group rather than in Omega's own workshops, it runs at 19,800 vph and offers around 42 hours of power reserve. The watch has been serviced and is completely original.

About Brand

What makes Omega an important vintage watch brand?

Omega is one of the most influential Swiss watch manufacturers, founded in 1848. The brand is known for combining technical innovation with durable, functional design. In the vintage watch market, Omega holds a strong position thanks to its in-house movements, consistent production quality, and historically significant models that remain highly collectible today.

Why is Omega significant in vintage watch history?

Omega played a central role in 20th-century watchmaking, from precision timing in international sports to professional tool watches. The brand supplied watches to military forces, served as official timekeeper of the Olympic Games, and famously supported space exploration. Early Omega Speedmaster models, along with military Seamaster references, are considered cornerstones of vintage watch history.

Are vintage Omega watches suitable for everyday wear?

Yes. Many vintage Omega watches were designed as robust tools or professional watches intended for daily use. Time-only models powered by movements such as the Omega caliber 30T2, caliber 26x, or later caliber 5xx and 6xx families are especially well regarded for their reliability. When properly serviced, a vintage Omega watch can be worn regularly while maintaining its value as a collectible vintage watch.

What should collectors look for when buying a vintage Omega watch?

When purchasing a vintage watch from Omega, collectors should focus on originality and correct configuration. Important factors include:

Original dial and hands with period-correct printing
Correct case reference and matching movement
Clear Omega serial numbers
Evidence of professional servicing

Original components and unaltered dials are key drivers of value in the vintage Omega market.

Which vintage Omega models are most collectible?

Some of the most desirable vintage Omega watches include:

Omega Speedmaster references such as CK2915, CK2998, and early Professional models
Omega Seamaster military and early dive references (including CK2913 and 300 series)
Omega Constellation chronometer models with pie-pan dials
Early manual-wind chronographs powered by the caliber 321

These models are highly valued for their historical importance, movement quality, and lasting design appeal.

Are vintage Omega watches a good investment?

Omega offers a strong balance between brand recognition, historical relevance, and long-term collectability. In the vintage watch market, Omega watches often provide better accessibility compared to some luxury peers while still offering documented heritage and in-house movements. Well-preserved vintage Omega watches continue to show steady collector demand and price stability.
