CASIO G-SHOCK Master of G Mudmaster- Armour Jacket Series

Part of the specialist Master of G series designed for use in the most extreme conditions, the new GG-B100Y watch combines a Carbon Core Guard case, a dust and mud-resistant structure that can withstand harsh land environments, with a new yellow accent colour to bring the series right up to date.

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.
