The G-Shock Mudmaster usually looks like something you’d pull from a rescue kit, construction vehicle or military supply crate. But with the new Master of G Land Mudmaster GG-B100XMH-5A, Casio has given the watch a literal glow-up, dressing it in dark brown resin and a light yellow-gold ion-plated stainless-steel bezel. 1/ 6 Front view of the Casio G-Shock Mudmaster GG-B100XMH-5A | Image: CasioDesign & Dimensions: Master of G Land Mudmaster GG-B100XMH-5ABrown and gold can certainly add a touch of class to a watch designed for professionals working in the toughest environments.

Its carbon-fibre-reinforced resin case uses Casio’s Carbon Core Guard structure, with shock resistance, mud resistance and 200 metres of water resistance.
