Vintage Omega Seamaster Cosmic DayDate Automatic 166.036 - 35mm - 1967

Omega Seamaster Cosmic Day-Date, produced in 1967. This watch features a beautiful white dial with golden and black accents, remaining in impeccable condition. The Day-Date complication displays both the date and weekday, with the weekdays able to be shown in English. The steel case is fully gold-capped and remains in incredible condition, with barely any gold fading which is quite uncommon. It also comes with its original Omega gold-plated beads of rice bracelet, which likewise retains its gold finish very well throughout. Inside sits a caliber 752 automatic movement, serviced in June 2026 and now running and functioning excellently. As the original bracelet fits wrists from 14.5 to 17 centimeters, we have also included an additional black leather strap with a crocodile motif, suitable for wrists from 12 to 20 centimeters. The overall condition of this piece is magnificent and examples like this will become increasingly more uncommon to find.
