Master of G-Land Mudmaster 51.3mm Black Dial

Built for mud, shock and rough terrain, the Casio G-Shock Master of G-Land Mudmaster, reference GGB100X-1A9, uses a 51.3 mm resin case with a carbon core guard structure, 19.4 mm thick. The black dial combines analog hands with a digital display and a double LED light.

A quad sensor suite covers thermometer, altimeter and barometer, digital compass and step counter. Further functions include world time, sunrise and sunset display, stopwatch, countdown timer and alarm, and a Bluetooth smartphone link. The quartz movement runs on a battery, and the bio-based resin band closes with a pin buckle. Water resistance is 200 meters. It is a large, feature-heavy outdoor watch for hikers and trail users who want sensors on the wrist.
