Features
Take on the toughest terrain with the G-SHOCK MUDMASTER, designed to handle the harshest, roughest on-land environments.
This shock-resistant watch is constructed to withstand all the mud and sand your adventures may bring, and it leverages our latest exterior technology to deliver a smaller profile with an even better fit.
This compact design is made possible by the forged carbon bezel, carbon core guard case structure, and mud-resist buttons combined with stainless steel pipes and silicone buffers. Finely powdered carbon fiber is kneaded into resin, then heat-pressed to mold a bezel that is more complex, yet even stronger than before.
Triple sensor measurements keep you updated with direction, altitude, barometric pressure, and temperature readings. Large Arabic numeral indexes, extra-thick arrow-shaped hands, double LED lights, and sapphire glass ensure high visibility.
The band is textured in the style of heavy-duty no-slip rubber grips, and the buttons are knurled for easy operation. A MUDMASTER designed for practicality, durability, and power.
