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 another step further with the ability to handle the roughest rubble and debris-strewn terrains, earning the appreciation and trust of rangers and rescue teams operating in extreme environments. The MUDMASTER GGB100X employs high rigidity carbon for the carbon fiber-reinforced case to keep damage and warping at bay and ensure a tight seal and excellent shock resistance. Featuring a filter to protect against mud, a stainless-steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibers, it provides a high level of resistance to dust and mud. The bezel also uses three layers of fine resin with carbon fiber inserts. The rugged design evokes the gasoline jerrycans mounted to off-road vehicles tough enough to traverse the most challenging terrain. Key components for the case and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.
