The Tissot Seastar 1000 Quartz Chronograph 38mm (T120.217.37.041.00) brings professional dive-watch performance into a refined, compact format suited for a wide range of wrists. Rooted in the Seastar collection’s deep-sea heritage, this model pairs exceptional water resistance with precise Swiss chronograph functionality. Its 38mm 316L stainless-steel case with carnation gold PVD coating is engineered to withstand pressures up to 30 bar (300 meters / 1000 feet), making it a serious tool watch for aquatic adventures. The graded turquoise dial adds vibrant personality while maintaining excellent legibility thanks to Super-LumiNova® hands and indexes. Powered by a Swiss quartz chronograph movement, it features precise timing functions, a screw-down crown and pushers, and a unidirectional rotating bezel for underwater reliability. Finished with a comfortable synthetic strap with quick-release capability, this Seastar delivers durability, precision, and bold style in equal measure.
