From the MASTER OF G Series MUDMASTER, the watch that is designed and engineered to withstand rough land environments, come carbon resin models that incorporate a new type of structure. The case is made of high-rigidity carbon material to protect against damage and deformation due to impact and other rough treatment, while metal button pipes ensure a tighter seal against the external environment. A filter further protects against the invasion of mud, for the high level of dust and mud resistance required when in severe environments. In addition, the dual back cover consists of a stainless steel panel back and an outer cover made of shock resistant fine resin embedded with glass fibers. Quad Sensor capabilities use compact sensors that make it possible to pack compass, altitude/barometer, and temperature measurements, along with an accelerometer that keeps track of your step count, into a compact configuration. A special G-SHOCK app, which simplifies configuration of watch settings, also includes a new Mission Function. The app automatically records altitude data measured by the watch and route information acquired by a smartphone's GPS. Manually obtained altitude points can be plotted on your route.
