Omega Seamaster Cosmic 2000 Ref.166.128 Cal.1012 38.0mm 1971

The deep black satin dial is framed by the Cosmic 2000’s broad, sculptural steel case, creating a striking contrast of light and shadow. Warm tritium accents lend a subtle sense of age, while the refined brushed surfaces keep the watch composed on the wrist. Inside, Omega’s high-beat Cal.1012 pairs dependable automatic performance with the collection’s bold design.

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. With the Cal.1012 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
