Ref: T120.417.17.051.01 | Swiss Quartz | 300m Diver's Watch | Brand New
The Tissot Seastar 1000 Chronograph (Ref: T120.417.17.051.01) is a bold Swiss Made professional diver's chronograph built for those who demand performance both underwater and on land. Combining a sleek black sunray dial with a stainless steel case and black rubber strap, this watch delivers a sporty, all-black aesthetic that looks equally sharp in the boardroom or at depth.
Engineered to ISO 6425 diver's standards, the Seastar 1000 features a unidirectional rotating dive bezel, screw-down crown with crown guard, and screw-down chronograph pushers — ensuring complete water integrity to 300 meters (1,000 feet). The scratch-resistant sapphire crystal with anti-reflective coating provides perfect legibility in any light, while the luminous plongeur-style hands deliver excellent underwater visibility.
Powered by the reliable Swiss Quartz ETA G10.211 movement, this is a high-precision timepiece that pairs professional-grade functionality with the timeless Swiss Made quality Tissot has delivered since 1853.
