Omega Seamaster Cosmic Ref. 166.023

The Seamaster Cosmic debuted in 1967, tapping into the growing excitement around space travel and the space race. Omega’s ongoing partnership with NASA further solidified its reputation as a preferred watchmaker, revitalizing the Seamaster line. Although its production run lasted less than a decade, it made a lasting impact.

The 1969 Omega Seamaster Cosmic Date 166.023 features a monocoque (from the French word “coque,” meaning hull) case design, crafted from a single piece of stainless steel. Accessing the movement requires removing the crystal using a special tool, highlighting the watch’s unique engineering.

The Seamaster Cosmic is an incredible vintage option within the Omega lineup, though it’s often underrated because of its 33mm size, which many consider too small. However, believe me, it wears beautifully on the wrist and would likely surprise many. The dial is gorgeous, and this watch, in its overall excellent condition, is definitely worth considering.
