Vintage Omega Seamaster Automatic 166.037 SP - 34,5mm - 1968

This vintage Omega Seamaster was produced in 1968. It features a beautiful white dial with a sunburst effect in almost perfect condition, however there is a very tiny spot between the 7 and 8 o’clock position. Inside is a caliber 565 automatic movement, which was serviced in February 2026 and currently runs and functions great. The stainless steel case measures 34.5 millimeters in width. The watch is paired with a brown top grain leather strap with a crocodile motive. This watch remains entirely original except for the freshly replaced leather strap.
