Combining the features you expect in a sports watch, this model is a timepiece you can trust—on, in, or under water. Impressive water-resistance up to a pressure of 30 bar (300m/1000 ft) is combined with the energy of a Swiss Made quartz movement. With a screw-down crown and case back, the Seastar 1000 Quartz GMT is ready for the water. Superluminova keeps it easy to read in the dark. The screw-down crown also offers additional protection against knocks.
