Casio G-Shock GN-1000 Watches

The youngest model of the Gulfmaster line is for sailors and just fans of the water element. The water style can be seen in many ways – from the round “diving” hour markers to the hands in the additional. windows, reminiscent of a ship’s anchor. In functional terms, GN is also very marine – there is a double sensor on board, consisting of a thermometer [measures air temperature] and a digital compass, pointing to the north and showing the degree measure of the angle in relation to the north. In addition, there is also a display of data on the phases of the moon and a tide sensor – also an important piece for tracking the water level in the ocean or sea. Bright illumination illuminates the dial in automatic mode.

From the GULFMASTER Series of watch designed and engineered to stand up to the rigors of maritime wear comes new collection of Twin Sensor models. A digital compass takes continuous readings for 60 seconds to help find your bearings at sea, and a thermometer feature helps to keep you informed about the environment around you. A Tide Graphfeature lets you check tide conditions whenever you want, while a Moon age indicator shows a graphic representation of Moon data. Both of these functions also support activities on the sea.
