The Tissot Seastar 1000 Chronograph is the instinctive choice for water sports lovers. Its impressive water-resistance up to a pressure of 30 bar (300 m/1000 ft) is combined with the energy of a Swiss-made quartz movement. And features all the element required in a useful instrument: screw-down crown and case back, unidirectional steel bezel with aluminium ring and highly luminescent material for excellent readability in the dark.
