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

MASTER OF G is a line of G-SHOCK watches that has been enhanced for professionals with tough functionality that can withstand the harshest conditions.

Among them, MUDMASTER is a tough watch designed for use in harsh environments where rubble and earth and sand are piled up and scattered, and has earned high praise and trust from rangers and rescue teams who work in extreme environments.

The GG-B100XMB-1AJF features a stainless steel mirror-finish bezel with black IP coating, providing high scratch resistance and a sophisticated, glossy finish.

The GG-B100XM-1AJF features a honed silver stainless steel bezel that is resistant to dirt and dust, and a matte finish that reduces light reflection for a calm look.

The case is made of highly rigid carbon fiber reinforced resin, which reduces breakage and deformation and ensures high airtightness and impact resistance.

In addition, it is equipped with a filter to prevent mud from entering, a stainless steel panel back, and an impact-resistant glass fiber reinforced resin back cover, providing high dust and mud resistance.

In terms of functionality, it can measure direction, altitude/barometric pressure, temperature, and steps.

In addition to easy watch settings using the dedicated app, it also comes equipped with several useful functions, such as a mission log that automatically records the altitude obtained from the watch and the route obtained from a smartphone in the app.

This is a tough watch that supports quick decisions and precise actions.
* Biomass plastic is used for the main resin parts of the case and band.

It uses renewable organic resources as raw materials and is expected to contribute to reducing environmental impact.
