Introducing the latest addition to the G-SHOCK MUDMASTER series. Part of the specialist Master of G series designed for use in the most extreme conditions, the new GG-B100 watch features the all-new Carbon Core Guard case, with a dust and mud-resistant structure that can withstand harsh land environments. The stark, all black GG-B100-1AER features red accent details on the dial, framed in a herringbone print, chrome finish bezel. 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. This provides the outdoor adventurer with the means to keep track of the surrounding environment while on the go. 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
