Vintage Omega Seamaster Automatic Date 166.0202 - 35mm - 1977

This vintage Omega Seamaster automatic was produced in 1977. It features a gold plated case measuring 35 millimeters in width. The dial is golden colored with a vertical brushed finish. The watch has a date window at the 3 o’clock position, powered by its caliber 1010 automatic movement, which was serviced in February 2026 and currently runs and functions great. We have chosen to pair this watch with a top grain leather strap with a crocodile motif. Overall, this piece can certainly be considered a dress watch, yet it also works very well as a daily wearer.
