Omega Seamaster Ref.166.0172 Cal.1012 35.0mm 1972

A sharp and refined example of the early-70s Omega Seamaster featuring a clean silver sunburst dial paired with elegant baton hands and indices with black inserts. This Reference 166.0172 from 1972 is powered by the reliable and high-beat Caliber 1012 automatic movement, complete with a convenient quickset date function for easy daily use.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or.
