The Omega Seamaster 120 Ref. 166.027 is one of Omega’s most iconic vintage dive watches. Introduced during the late 1960s, the Seamaster 120 offered a slimmer and more versatile alternative to larger professional dive watches while maintaining the rugged design language that made Omega dive watches famous.

This 1969 example features a black dial with aged lume plots, a date display at 3 o’clock, and the renowned Omega Caliber 565 automatic movement. The asymmetrical case design, sharp lyre lugs, and rotating dive bezel give the watch a distinctive vintage tool-watch character that remains highly sought after by collectors today.

Powered by the respected Caliber 565, this watch benefits from one of Omega’s finest automatic movements of the era, known for its reliability, smooth operation, and quick-set date function.

The watch retains its vintage charm with attractive patina throughout. The bezel insert has been replaced. Fitted with an aftermarket rubber strap.
