Seastar 1000 and Seastar 2000 Professional
The Seastar 1000 is the everyday diving watch of the line: water resistant to 300 metres, with a ceramic bezel and available in sizes from 36 to 45.5 mm. The Seastar 2000 Professional is the technically more elaborate version with 600 metres of water resistance, a helium valve and a diver's extension on the folding clasp. Both versions work either with quartz or with the Powermatic 80 and carry luminous material on the hands, indices and bezel.
What matters in a diving watch
The decisive points are the unidirectional bezel, which can only be turned counterclockwise and therefore never shows the dive time as shorter than it is, the screw-down crown and a luminous material that remains legible in the dark even after hours. All Seastar models meet these points. The helium valve of the Seastar 2000 Professional is designed for saturation dives and has no function in everyday use, but is part of the professional design of the watch.
