The Tissot Seastar 1000 merges style and performance without compromising either. The diving inspiration shapes both the appearance and the functionality of this watch. It maintains its performance to a pressure of 30 bar (300m/1’000ft), combining underwater sports and a preference for a sophisticated Swiss timepiece. The diving theme continues through elements such as a unidirectional bezel, a strap with a divers’ buckle and extension, plus luminescent hands and markings. All models with automatic movements in the family have their own helium valve, which allows to automatically depressurize the watch. The Tissot Seastar 1000 Powermatic 80 powered by an automatic Powermatic 80 Swiss movement of up to 80 hours power reserve reconfirms the proven Tissot talent for encapsulating operational excellence in stunning design.
