GG-B100X-1A3ER

For the intrepid adventurer and nature lover, the rugged and robust GG-B100X MUDMASTER is here – a watch designed to withstand the most extreme conditions. This model from the Master of G range combines high-performance construction with environmentally responsible materials, offering uncompromising durability.

G-SHOCK Master of G watches, developed for professionals working in hostile environments, incorporate advanced functions and superior durability. The MUDMASTER goes one step further, ready to tackle terrain covered in debris, mud and adverse conditions, earning the trust of forest rangers and rescue teams in extreme situations.

The GG-B100X features a high-rigidity carbon fibre-reinforced case that prevents deformation and damage, ensuring a watertight seal and excellent impact resistance. It includes a mud guard, a stainless steel back cover and a thin fibreglass-reinforced resin back cover, ensuring high resistance to dust and mud. The bezel is composed of three layers of resin with carbon fibre inserts, giving it a robust design inspired by the fuel cans used on off-road vehicles.

Furthermore, it incorporates bio-based resins in key components such as the case and strap, a material made from renewable organic resources that helps reduce environmental impact.

Highly functional, this watch features a digital compass, altimeter/barometer, thermometer and step counter. It allows you to easily set the time via a dedicated app and offers advanced functions such as Mission Log, which automatically records altitude data from the watch and routes from your smartphone.

An reliable companion in any environment, the GG-B100X MUDMASTER is designed to help you make quick decisions and act with precision when you need it most.
