Casio began with the renowned shock resistant G-shock structure & has innovated a new mud-resistant structure G-9300, that is equipped with functions and features that withstand the harshest of environments. G-9300 MUDMAN is shock resistant, mud resistant & consist of twin sensors that can help you keep your bearing wherever your adventure takes you. A one-touch easy access button goes directly to compass & thermometer mode and a moon phase graph can help to determine whether the nighttime hours will be dark or light. Not only is a knobby bezel shape employed to guard against external shocks, but the surface of the case features a hard form as well. A soft surface is adopted for the case back, on the other hand, to assure comfortable wear on the wrist. The result is a skillful combination of strength with gentleness.
