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 unidirectional ceramic bezel. It is fitted with an automatic movement. An automatic watch is powered by the energy of the person who wears it. Wrist movement enables the mechanism to run. The Powermatic 80 movement boasts 80 hours of power reserve, which is enough to continue telling time accurately even if the watch is not worn for three days. It is an innovative movement that outperforms the competition, whose movements generally provide 1.5 days of power reserve*. *Non-contractual image
