Seastar 1000 Chronograph T1204171705103

The Tissot Seastar 1000 is the ultimate diving watch, with its high water-resistance up to a pressure of 30 bar (300 m/1000 ft), screw-down crown and case back as well as its unidirectional ceramic bezel. This product is not available for sale in the state of California. Ensuring visibility under all conditions is an important goal for Tissot. This is why some timepieces feature a material we call SuperLuminova®. This material is placed on visible parts such as dials and hands, where it functions as a miniature accumulator of reflected light when the watch finds itself in the dark*.
