New PRC 100 Solar styles are here. Shop now This collection has been created for real watersport lovers. 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 aluminum bezel ring. 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
