Tissot Seastar 1000 Chronograph T120.417.17.051.02 Black Dial Rubber Strap. Swiss precision at a price point that doesn't ask you to compromise — that's the Tissot T120.417.17.051.02. From the Seastar 1000 collection, the T120.417.17.051.02 measures 45.5mm — commanding attention without being excessive. At 109g, it sits comfortably without disappearing.. The sapphire crystal protecting the black dial resists scratches far better than standard glass — a genuine upgrade. With 300m (30 ATM) 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. Sub-dial chronograph function brings real-world utility to the design. Lume-coated hands and indices keep the time visible in low-light conditions. A ETA G10.212 quartz movement keeps time accurately and reliably, year after year.. Specifications.
