The Tissot Seastar 1000 Chronograph 45.5 mm (T120.417.17.051.03) delivers professional-level dive functionality wrapped in bold styling.

Powered by a precision Swiss quartz chronograph movement, the watch features central 60-second, 30-minute and 1/10-second counters, a date display and a robust layout for timing performance. Built for the deep, it offers a 300 m (30 bar) water-resistance rating, a screw-down crown and case-back, and a scratch-resistant sapphire crystal with double-sided anti-reflective coating for clarity and durability. At 45.5 mm in diameter, the case commands presence while the black PVD finish adds modern edge and durability. Whether diving, travelling or simply making a statement, this Seastar 1000 model is engineered for style and substance.
