Tissot Seastar 1000 45.5mm
 
 
The Tissot Seastar 1000 is the ultimate watersport 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 aluminum ring and highly luminescent material for an excellent readability in the dark.
