This is the radio-controlled solar model from the G-SHOCK “Mudmaster” series, designed for extreme on-land use where debris and dirt are piled high or scattered everywhere. To withstand use in harsh environments, the buttons feature a button guard cylinder structure that provides dust and mud resistance. A cylindrical tube that protects the buttons, combined with a gasket built into the buttons, prevents fine sand and mud from entering. The design evokes the rugged image of specialized vehicles and tools used in disaster relief operations. To ensure high visibility even in harsh conditions, it features wide hour and minute hands and large Arabic numeral indices. The band features a textured finish inspired by anti-slip grips, and the overall design is infused with a military aesthetic throughout. This G-SHOCK is designed to support the tough men who undertake grueling missions on land.
