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 GG-B100X 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.
Practical and functional, the watch is equipped with digital compass, altimeter/barometer, and thermometer, as well as step counter. Easily correct the time using the dedicated 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.

Built not to break

A module that floats
Inside a hollow case, the module (the heart of the watch) seems to float, so knocks from outside are softened before they reach it. The idea came from watching children play with a rubber ball.

2-year warranty
Every G-SHOCK watch from Watch Direct comes with a 2-year warranty from Shriro Australia, Casio’s exclusive Australian distributor.
Watch Direct is an authorised G-SHOCK retailer, trading since 2011.

About G-SHOCK

G-SHOCK began with a dropped watch. Casio designer Kikuo Ibe saw a watch break when it fell, and proposed “a durable watch that would not break even if dropped”. The project set itself the “Triple 10” goal: survive a 10-metre drop, resist water to 10 bar and run for 10 years on one battery. The first G-SHOCK, the DW-5000C, arrived in 1983.
