G-SHOCK watches from the Master of G line, developed for professionals who work in the harshest environments, are equipped with even more demanding features. And MUDMASTER goes even further, with the ability to tackle the world's toughest land environments, earning the recognition and trust of rangers and rescue teams operating in extreme environments.

The comfortably sized GWG-B1000 features a metal exterior designed using high-precision forging techniques and a carbon fiber-reinforced resin case that provides high strength and exceptional durability.

Radio-controlled and solar-powered, the watch also features a triple sensor that keeps the user updated with direction, altitude, barometric pressure and temperature readings. The dual LED lights and sapphire crystal ensure high readability so you can always see the time and other information, regardless of lighting conditions.

Enter a specific location in the app and the Location Indicator function moves the indicator hand at the 3 o'clock position to point in that direction, so you always stay on track, even when visibility is obstructed by extreme conditions such as sandstorms .

The use of biological resins in the manufacture of the case, some components of the bezel and the watch bracelet demonstrates MUDMASTER's commitment to the environment.
