The Casio G-Shock Mudmaster GG-B100X-1AER is a rugged men's watch from the Master of G Land line, developed specifically for professional use under the harshest conditions. The case is constructed from high-rigidity carbon-reinforced resin, integrated into the Carbon Core Guard architecture to deliver outstanding protection against shocks, dirt and mud. The bezel insert combines three layers of resin with carbon fibre inserts for maximum structural integrity. Key components of the case and strap are made from bio-based resin derived from renewable resources, reducing the overall environmental footprint.
