For the fearless adventurer and nature lover, a tough and rugged Master of G MUDMASTER featuring bezel and case constructed of heavy duty carbon and environmentally responsible materials.
The watches of the G-SHOCK Master of G line, developed for professionals working in the harshest environments, come equipped with even tougher functionality. And the MUDMASTER takes this even further with the ability to handle the roughest on-land environments, earning the appreciation and trust of rangers and rescue teams operating in extreme environments.
The GG-B100 MUDMASTER employs high rigidity carbon in the case to keep damage and warping at bay and ensure extreme airtightness and shock resistance. This timepiece also features a filter to protect against mud, a stainless steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibres, giving it a high level of resistance to dust and mud. The bezel also uses three layers of fine resin with carbon fibre inserts. The rugged design evokes the gasoline jerrycans mounted to off-road vehicles tough enough to traverse the most challenging terrain. Key resin components of the case and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.
Practical and functional, this watch is equipped with digital compass, altimeter/barometer, thermometer and step counter. Easily correct the time using the dedicated CASIO WATCHES app, and tap into loads of other useful features including the Mission Log, which automatically records altitude data obtained from the watch and route data obtained by your smartphone.
You can depend on this tough timepiece to deliver what you need to make quick decisions and take decisive action
