This radio solar model from the G-SHOCK MUDMASTER series is intended for extreme on-land use in terrains strewn with rocks, sand, and debris. Features a dust- and mud-proof structure needed for missions in dirt, sand, and mud. A large number of gaskets built into the buttons and shafts prevent mud intrusion. A vibration-resistant structure makes it able to withstand the use of large pieces equipment such as electric cutters or crushers. It is also equipped with a triple sensor that displays information on orientation, atmospheric pressure/altitude, and temperature. High visibility is also ensured via large indices with Arabic numerals, a double LED light, and a wind-proof sapphire glass crystal. The band is textured to resemble the non-slip grip of a piece of heavy machinery, and the extra-thick hour and minutes hands have an arrow feather motif. Checkering is applied to all buttons to improve operability and to provide a finish that exudes a military feel. A G-SHOCK that supports tough men on harsh land missions.
