Mudman GW-9500-1A

Conquer even more terrain with enhanced support — A rugged timepiece in a bold, powerful, triple-sensor design.

The G-SHOCK Master of G line of watches developed for professionals working in the harshest environments introduces the triple-sensor MUDMAN with mud-resist construction. The large, easy to operate front button and three direct sensor buttons on the side are shaped to drain mud and water and are protected by cylinder-shaped stainless steel components.

The button shafts are equipped with gasket fittings to keep mud and dust out, as well, so you’re ready to take on the toughest of terrains. The bold design features a dual-layer LCD, as well as the Triple Sensor to deliver altitude, direction, temperature and barometric pressure readings directly to your wrist.

The thin module and Carbon Core Guard structure mean all these features live in a slimmer, more compact watch, for tough and rugged support with a comfortable fit. Slim, yet powerful, this MUDMAN design packs full-on functionality in a striking exterior built with an intricate combination of components. The digital compass is more practical than ever thanks to the dual-layer LCD, which displays compass graphics on the top layer and time and other readings on the layer below.

The GW-9500-3 and GW-9500-1A4 feature a negative dual-layer LCD.

Taking utility to a whole new level, radio-controlled solar power delivers precision timekeeping powered by light, while Super Illuminator ensures visibility, even in dark places. The case, bezel and urethane band are made with bio-based resins derived from renewable organic resources. The case back is engraved with the iconic MUDMAN mole character holding a compass.
