Regular price $460.00

The watches of the G-SHOCK Master of G line, developed for professionals working in the harshest environments, come equipped with even tougher functionality. And the MUDMASTER takes this another step further with the ability to handle the roughest rubble and debris-strewn terrains, earning the appreciation and trust of rangers and rescue teams operating in extreme environments. The GGB100XM-1A features a silvery stainless-steel bezel with a honing finish, delivering outstanding scratch resistance that protects against mud and dust and a subtle matte texture that minimizes reflected light. The stainless-steel GGB100XMB-1A bezel is ion-plated in black with a mirror finish for both outstanding scratch resistance and a refined luster. These MUDMASTER employ high rigidity carbon for the carbon fiber-reinforced case to keep damage and warping at bay and ensure a tight seal and excellent shock resistance. Featuring a filter to protect against mud, a stainless-steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibers, these timepieces provide a high level of resistance to dust and mud. Key components for the case and band are made with bio-based resin. Produced using renewable organic resources, this material is expected to help reduce environmental impact.

G-SHOCK, the watch that brought the new concept of toughness to the timepiece.
It began with a reckless challenge to the conventional wisdom of the day, a developer’s belief that it was possible to construct a watch that wouldn’t break, even if dropped. Project Team Tough was formed to build it in 1981.
The team created over 200 prototypes one after another over a period of about two years. They finally arrived at a shock-resistant structure. This marked the birth of a technology that is tough to the core.
And G-SHOCK has continued its unceasing evolution ever since, in pursuit of greater toughness in every respect, from structure and materials to functions. Today, the development team’s passion for challenge and constant efforts have reached fruition in Triple G Resist, a structure with the strength to withstand 3 types of gravitational acceleration.
