Tissot Seastar 1000 Chronograph T120.417.11.041.01

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 caseback as well as its unidirectional steel bezel with aluminium ring and highly luminescent material for an excellent readability in the dark. A sapphire crystal gives a watch the following properties: extremely high resistance to impact and superior screen and hand readability thanks to its transparency. Because it is the strongest material after diamonds, it is used in fine timepieces for its anti-scratch prowess. Sapphire crystals can take many forms and give the watch a variety of looks: flat, domed, concave or ground.
