Details: BASEL, March 16, 2016 - Casio Computer Co., Ltd. announced today the release of the new FROGMAN GWF-D1000 diver's watch, a new addition to its G-SHOCK line of shock-resistant watches. The GWF-D1000 is equipped with triple sensors and is designed to withstand the toughest of underwater missions. Shock-resistant FROGMAN diver's watches feature ISO 200-meter water resistance and a unique asymmetric shape that leaves wrist movement unrestricted. Since releasing the first FROGMAN DW-6300 watch in 1993, Casio introduced the DW-8200 (1995) featuring rust-resistant titanium materials, the DW-9900 (1999) with a small form factor, the GW-200 (2001) with Solar Power, and the GWF-1000 (2009) that receives time-calibration radio signals from six global broadcast stations. FROGMAN watches have continued to evolve by incorporating the latest technologies available. The FROGMAN GWF-D1000 represents another major step forward in the evolution of FROGMAN watches, with three precision sensors for measuring water depth, temperature, and compass bearing, and it is designed for use in the toughest environments including marine rescue. The GWF-D1000 also marks a first for the FROGMAN Series, with a water depth function that measures the depth down to 80 meters in 10 centimeter increments. The temperature function measures water temperature in 0.1 degree Celsius increments, and the compass bearing function, which features auto horizontal compensation, measures bearing in one degree increments even when tilted. These sensors provide real-time measurement data to support underwater search and rescue activities. The watch comes with an array of pro-grade features including a tide graph that displays high and low tides and a log memory function to track diving activities (dive time, maximum water depth, and lowest water temperature), supplemented by an excessive ascent rate alarm.
