Vintage Omega Seamaster DayDate “Sparkle dial” ST 166.032 / 168.023 - 36,5mm - 1970

This vintage Omega Seamaster DayDate, produced in 1970, remains in beautiful condition. It features a white “sparkle” dial that lightly glitters under certain light, with a daydate display at the three o’clock position showing weekdays in English. The 36,5mm stainless-steel case retains most of its original polishing, a notable detail for a watch of this age.

Inside is the caliber 752 automatic movement, serviced in December 2025 and now running and functioning perfectly. The watch is paired with a black calf leather strap featuring a crocodile-grain motif. Overall condition is excellent, making it suitable as both a daily wearer and a refined dress watch.
