New PRC 100 Solar styles are here. Shop now The Tissot Seastar 1000 is the ultimate watersport watch, with its high water-resistance up to a pressure of 30 bar (300 m/1000 ft), screw-down crown and caseback as well as its unidirectional aluminum bezel. Ensuring visibility under all conditions is an important goal for Tissot. This is why some timepieces feature a material we call SuperLuminova®. This material is placed on visible parts such as dials and hands, where it functions as a miniature accumulator of reflected light when the watch finds itself in the dark*. *Non-contractual image
