Vintage Omega Constellation Ref. ST 168.0056, Cal. 1011, C-Shape Case, Swiss Watch from 1973

This 1973 Omega Constellation Ref. 168.0056 is a classic example of the brand’s signature 1970s design language — clean, sharp, and unmistakably modernist. The C-shape case, introduced in the late '60s, was a bold departure from traditional round profiles and is now a highly recognizable design.

Crafted in stainless steel, the case measures 35mm wide by 40.3mm lug-to-lug, with a slim, elegant wrist presence. The silver dial is beautifully preserved, featuring applied baton hour markers, a framed date window at 3 o’clock, and the signature Omega star above 6.

Powering the watch is the Omega Caliber 1011, a chronometer-certified automatic movement with a quickset date function. The serial number 37684862 places production in 1973, during a period when Omega was pushing boundaries in both design and precision.

The caseback proudly bears the Observatory medallion, symbolizing Omega’s dedication to accuracy in chronometry competitions.
