G-SHOCK MASTER OF G MUDMASTER Watch, 51mm - GG-B100X-1A3ER

For the fearless adventurer and nature lover, a robust and tireless Master of G MUDMASTER with a case and bezel made of durable carbon and materials with a reduced environmental impact.

The G-SHOCK Master of G watch line, developed for professionals operating in the most extreme environments, is equipped with even more advanced features. MUDMASTER goes further, with the ability to tackle the harshest land environments, earning the appreciation and trust of rangers and rescue teams working in extreme conditions

The GG-B100 MUDMASTER uses high-rigidity carbon for the case, to prevent damage and deformation and ensure exceptional water resistance and impact resistance. This timepiece is also equipped with a mud filter, a stainless steel case back, and a fine resin inner panel reinforced with fiberglass, to offer high protection against dust and mud. The bezel also uses three layers of fine resin with carbon fiber inserts. The robust design recalls the fuel cans mounted on off-road vehicles capable of tackling the most difficult terrain. The main resin components of the case and strap are made of bio-based resin, obtained from renewable organic resources, a material that should help reduce the environmental impact.

Practical and functional, this watch is equipped with a digital compass, altimeter/barometer, thermometer, and pedometer. It is possible to easily set the time using the dedicated CASIO WATCHES app and access numerous other useful functions, including the Mission Log, which automatically records the altitude data obtained from the watch and the route tracked by the smartphone

You can rely on this robust timepiece to have everything you need to make quick decisions and get straight to action.

FEATURES
Shock, dust, and mud resistant structure thanks to carbon fiber-reinforced resin
The carbon fiber-reinforced resin case protects the module, offering sturdiness, lightness, and excellent resistance to the elements. The gaskets are applied around the buttons to ensure a hermetic seal, guaranteeing reliable resistance to dust and mud even in difficult environments. Carbon fiber-reinforced resin is also used for the cover enclosing the case back and for the moving parts on the lower side of the strap, improving both durability and comfort of use.
