Casio G-Shock Mudmaster Pro GG-B100X-1A3ER

The Casio G-Shock Master of G series MUDMASTER is designed for demanding conditions – for professionals and adventurers who work in mud, dust and rocky terrain. The GG-B100X-1A3ER combines a carbon fiber reinforced structure, versatile sensor functions and modern smartphone connectivity into an exceptionally durable unit.

The watch's carbon fiber reinforced Carbon Core Guard structure ensures excellent shock resistance and rigidity. The three-layer bezel with carbon fiber inserts and a mud-resistant structure keep fine dust and dirt at bay. The back cover is made of stainless steel and the protective structures are made of fiberglass reinforced resin. The watch also has parts made of bio-based resin, which reduces environmental impact.

This MUDMASTER is not just a durable work tool – it is a full-fledged multi-function watch for outdoor enthusiasts. A digital compass, altimeter, barometer, thermometer, and pedometer provide real-time information about your surroundings. Bluetooth® connectivity connects the watch to the CASIO WATCHES app, allowing you to automatically adjust the time, record routes with the Mission Log function, and utilize a variety of additional features.

When conditions demand quick decisions and reliable equipment, the GG-B100X-1A3ER is up to the task.
