CASIO Master of G Mudmaster Watch Green/Carbon

From Casio G-Shock, the innovators of tough timekeeping, comes the GGB100 Master of G Mudmaster watch series that has been designed to endure the toughest environments. This watch features a carbon core guard structure case, in black with grey accents, that allows the internal mechanics of the watch to be protected from shock-induced damage. This watch is mud resistant with metal buttons that form a tight seal on the case, a dual back cover that consists of a stainless steel panel back and an outer cover made of shock resistant fine resin embedded with glass fibers, and the bezel has three layers of fine resin with carbon fiber inserts. The Quad Sensor capabilities provide instant access to a compass, altitude/barometer, thermometer, and an accelerometer that keeps track of your step count. Additionally, this watch connects via Bluetooth to a special G-Shock app that helps with the configuration, as well as records altitude data, route information, and step counts. These recordings are used to create an activity log you can use for tracking. Mode Switching Customization allows you to turn on and off individual modes and their sequence, for a personalized feel.
