Combining all the elements you would expect in a sports watch, this model is a timepiece you can rely on Ð on, in or under the 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 and Superluminova ¨ ensuring it is readable in the dark, the Seastar 1000 Quartz GMT is an aquatic ace that truly has it all. The screw-down crown also offers additional protection against knocks.
