As per usual, Casio's new Gulfmaster goes above and beyond with their latest water-specific tool watch. The GWN-Q1000 has a laundry list of features such as a Multiband receiver that automatically adjusts the time across the globe, a water depth sensor, and a compass, altimeter, barometer, thermometer, moon data, and of course, a tide graph. For traveler the world time function gives you time in 48 cities and 31 time zones and a high capacity solar charger helps the watch stay charged for almost two years of continuous usage (with power saving function enabled).
