GG-B100XMB-1A

Built for those who thrive in extreme conditions, the Master of G MUDMASTER delivers uncompromising toughness with a robust metal bezel designed to stand up to the elements. Created for professionals operating in the harshest environments, the G-SHOCK Master of G range is engineered with advanced durability at its core. The MUDMASTER pushes this further, purpose-built to perform on land where mud, dust and impact are a constant challenge. It’s a timepiece trusted by rangers and rescue teams working at the limits. The GG-B100XM-1AER features a silvery stainless-steel bezel with a honed finish, offering excellent scratch resistance and protection from mud and debris, while its subtle matte texture reduces unwanted reflections. The GG-B100XMB-1AER takes a darker approach, with a black ion-plated stainless-steel bezel finished to a mirror sheen that balances durability with refined presence. At the heart of the GG-B100 MUDMASTER is a high-rigidity carbon case that resists damage and distortion while maintaining exceptional airtightness and shock resistance. A dedicated mud-resistant filter, stainless-steel screw-back and a shock-resistant resin back cover reinforced with glass fibres work together to provide outstanding resistance to dust and mud. Selected case and band components are made from bio-based resin derived from renewable organic resources, helping to reduce environmental impact. Designed for real-world utility, this watch is equipped with a digital compass, altimeter and barometer, thermometer and step counter. Time correction is simple via the CASIO WATCHES app, which also unlocks features such as Mission Log, automatically combining altitude data from the watch with route data from your smartphone. When every second counts and conditions are unpredictable, this is a watch you can rely on to support fast decisions with style.
