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.
