This is a model from the G-Shock Mudmaster Series, designed for use in extreme environments scattered with rubble, dirt and debris. It was created in collaboration with the British Army. It is based on the GG-B100, which uses carbon materials to provide shock, dust and mud resistance while also featuring compass, altimeter/barometer, temperature measurement and pedometer functions. Under the supervision of the British Army, both the watch and its packaging feature camouflage patterns reminiscent of camo clothes. The army logo is depicted on the band ring and packaging, and the model has been given other finishing touches befitting such a collaboration, including metal for the band ring's material. This is a special collaboration model between the British Army, who participate in the toughest of missions, and G-Shock, which supports their activities with the most advanced watch features.
