Overview
The GWNQ1000 GULFMASTER comes equipped with four sensors, designed to provide vital information about constantly changing ocean conditions to coast guard crews who respond to emergency situations on rough seas. In addition to being the first G-SHOCK analog model equipped with a depth sensor, the watch also comes equipped with a barometric pressure sensor that can be used to predict upcoming weather changes, a temperature sensor that detects the change of air and water temperature, as well as a digital compass that can be used to determine wind and tide direction. An auto-level correction function detects the angle of the watch during digital compass readings and compensates accordingly to ensure correct readings while aboard a rocking boat.
