Omega Seamaster Ref.166.0216 Cal.1020 35.0mm 1984

A refined 1970s Omega Seamaster Ref.166.0216 in stainless steel, paired with a pristine silver sunburst dial that shifts beautifully under light. The iconic integrated bracelet case gives it quiet presence without ever feeling loud. With its clean lines, sharp architecture, and balanced proportions, this is the kind of Seamaster that slips under a cuff and still gets noticed by the right people. Elegant, collectible, and effortlessly classy. Exactly what vintage Omega does best.

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.1020 inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
