Two new models from the G-SHOCK "Master of G" series, designed for use in extreme conditions, have been released, clad in a matte black finish.

From the "Master of G" series, which is designed for even more extreme conditions within the toughness-pursuing G-SHOCK line, two new models have arrived. They are thoroughly black, emphasizing the texture of the resin and their rugged design. The "GG-B100-1BJF," based on the Mudmaster GG-B100, is designed for use in extreme terrestrial environments such as rubble and scattered debris, achieving new shock, dust, and mud resistance through its carbon fiber construction. It also features sensor functions and smartphone connectivity to support accurate judgment and action in various situations.

Meanwhile, the "GW-9400J-1BJF," based on the Rangeman GW-9400, is a model that pursues "ultimate survival toughness," created for use in one of Earth's harshest environments: hot and humid jungles and dense forests. It newly incorporates a "button guard cylinder structure" that reduces impact on the large metal buttons, enabling smooth and accurate operation. Furthermore, it includes a direct time stamp function to record the time with a single push, G-SHOCK's first triple sensor capable of measuring altitude, direction, barometric pressure, and temperature, and Multi-Band reception compatible with six global stations, including two in Japan, along with Tough Solar power. This ensures high usability and operability.
