Product Features

From G-SHOCK, which has been pursuing toughness since its inception in 1983, comes the MASTER OF G MUDMASTER, featuring a bezel made of highly durable metal components.

MASTER OF G is a line within G-SHOCK that offers enhanced, rugged functionality designed for professionals to withstand extreme conditions. Among these models, the MUDMASTER is a rugged watch engineered for use in harsh environments where debris and dirt are piled high or scattered about. It has earned high praise and trust from rangers and rescue teams operating in extreme conditions.

The GG-B100XMB-1AJF features a mirror-finished stainless steel bezel with a black IP coating, combining high scratch resistance with a sophisticated luster.
The GG-B100XM-1AJF features a silver stainless steel bezel with a honed finish, which enhances scratch resistance against mud and dust while providing a subdued, matte texture that minimizes light reflection.

The case utilizes high-rigidity carbon fiber-reinforced resin to prevent breakage and deformation, ensuring high water resistance and shock resistance. Additionally, it is equipped with a mud-proof filter, a stainless steel panel back, and a shock-resistant glass fiber-reinforced resin back cover, providing excellent dust and mud resistance.

In terms of functionality, it measures direction, altitude/barometric pressure, and temperature, and also tracks steps. It also features a dedicated app for easy watch setup, as well as several useful functions such as Mission Log, which automatically records the altitude data collected by the watch and the route data from your smartphone within the app. This is a rugged watch designed to support quick decision-making and precise action.

* Biomass plastic is used for the main resin parts of the case and band. Made from renewable organic resources, it is expected to contribute to reducing environmental impact.
