First 5 Orders Receive Limited Edition G-Shock Frogman Statue with Purchase.

The amphibious G-SHOCK FROGMAN continues to evolve in its technology and features. The GWFD1000B-1 is designed with triple sensor technology featuring a new water depth gauge that measures down to 80 meters in 10 centimeter increments, digital compass (with automatic horizontal correction) that measures bearing in one degree increments even when tilted, and thermometer that measures water temperature in 0.1 degree Celsius increments, in addition to an array of pro-grade features including high-visibility, full Auto LED light, a tide graph that displays high and low tides as well as a log memory function to track diving activities (dive time, maximum water depth, and lowest water temperature), supplemented by an excessive ascent rate alarm. These advancements were developed after conducting special interviews with a professional rescue team of the Japan Coast Guard. The updates help divers grasp the environmental changes at deep sea levels and provide real-time measurement data.
