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 fibre is kneaded into resin, then heat-pressed to mould 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.

Forged carbon bezel

The bezel is made from forged carbon fibre, a composite material used in aircraft fuselages, at the 12 and 6 o’clock positions. Carbon fibre-reinforced resin is forged in a press die at high temperature and pressure, producing strong, lightweight parts with complex shapes.

Carbon Core Guard structure

Offering strength, lightness, and excellent durability, the carbon fibre-reinforced resin case protects the module. These properties of carbon fibre made it possible to reduce the size of the case, which is 1.5mm slimmer than the previous model (GWG-1000).

Dust and mud-resistant structure to support land missions in the harshest conditions

Newly developed Mud Resist buttons combine with stainless steel button pipes and a silicone buffer material to add toughness that will withstand long-term use.

Dial designed for optimum visibility outdoors

The large-diameter dial gives a sense of depth and makes room for the large dimensional index marks. The mode indicator at the 9 o'clock position has an arrow-shaped hand and is angled to offer better visibility from a low angle.

Exterior design inspired by professional gear

Design details are inspired by professional gear, including the fine texturing on the band, the checked surface texture of the crown, and ribbed guards to protect the front buttons. The exterior design offers both practicality and aesthetic appeal.

Super Illuminator (high-brightness double LED light) for maintaining watch readability in the dark
