This is a Twin Sensor model from the G-Shock Mudmaster Series, designed for use in extreme environments scattered with rubble, dirt and debris. With a push of one large button at the 3 o'clock position, you can check your position with its Compass. The temperature can also be measured easily by pushing the button at 4 o'clock. This model has been developed with operability in mind so that anyone can intuitively check their position using the Compass, even in the most extreme climates, without visual observation. The dust and mud-resistant button guard cylinder structure prevents fine sand and mud from getting into the buttons while also helping to absorb any shock to the buttons and improving operability. Broad hour/minute hands and indices of large Arabic numerals have also been adopted to improve visibility. This design is packed with military-style flare, including a mode display that uses a sprocket-inspired disk dial and a textured band to prevent slipping.
