Casio has introduced two new models in its G-Shock Master of G collection, designed for extreme military and alpine conditions. Priced at £369 each, the MUDMASTER GG-B100XM-1A and GG-B100XMB-1A feature advanced protection and sensors for outdoor activities. These watches emphasize durability and functionality over style.
The Casio G-Shock line has long been recognized for its affordability, reliability, and toughness, making it suitable for daily wear or demanding adventures. The latest additions to the Master of G series, announced on March 6, 2026, are built to withstand the harshest environments, potentially marking them as the most resilient in the range.
Both models, the GG-B100XM-1A and GG-B100XMB-1A, incorporate a stainless-steel bezel formed through complex forging for enhanced strength. They are housed in a high-strength case made from carbon fibre-reinforced resin, providing additional safeguarding. To further bolster their resilience, heavy-duty gaskets seal the buttons, creating a hermetic barrier against dust and mud even in severe weather.
Functionality is a key focus, with each watch equipped with a Quad Sensor that gauges compass bearing, altitude, and temperature. An integrated accelerometer monitors step counts, enabling users to track activity history and observe shifting weather conditions. A high-brightness LED light ensures readability in low-light situations.
The primary distinction between the two is aesthetic: the GG-B100XM-1A sports a silver-coloured bezel with a matte finish, while the GG-B100XMB-1A features a black ion-plated bezel. At £369, these watches sit at the higher end of G-Shock prices but offer substantial value through their robust construction and practical tools for adventurers seeking performance rather than mere appearance.
