This is a model from the G-Shock Mudmaster Series, designed for use in extreme environments scattered with rubble, dirt and debris, and uses carbon materials. The use of high rigidity carbon on the case keeps damage and deformation at bay and ensures a high level of airtightness and shock resistance. This model also features a filter that protects against the invasion of mud, a stainless-steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibers, giving it a high level of resistance to dust and mud.Function-wise, this model comes with compass, altimeter/barometer, temperature reader and pedometer. In addition to being able to easily correct the time using the dedicated CASIO WATCHES app, there are lots of other useful features including the Mission Log feature, which automatically records in the app altitude data obtained from the watch and route data obtained by your smartphone.
