Tissot Seastar 1000 T120.417.17.421.00 Men's Watch – 45.5mm Red Dial Rubber. Swiss precision at a price point that doesn't ask you to compromise — that's the Tissot T120.417.17.421.00. From the Seastar 1000 collection, the T120.417.17.421.00 measures 45.5mm — commanding attention without being excessive. At 109g, it sits comfortably without disappearing.. A sapphire crystal face means the red gradient dial stays pristine, even with daily wear. With 30 bar (300 m / 1000 ft) water resistance, this is a genuine tool watch — swimming, snorkelling, and serious water exposure are all fair game. A rubber strap keeps things lightweight and active-ready — flexible, quick-drying, and comfortable in any conditions. Chronograph sub-dials add functional timing to the dial — handy for everything from cooking to commuting. Luminous hands and markers ensure readability after dark — no reaching for your phone. A ETA G10.212 quartz movement keeps time accurately and reliably, year after year.. Specifications. Barcode / EAN. 7611608294932. Bezel. Unidirectional rotating bezel with aluminum insert. Brand.
