Whatever you’re doing, wherever you are — the G-SHOCK Master of G line has your back. Based on GRAVITYMASTER, MUDMASTER, and MUDMAN models that deliver peak performance in punishing conditions in the air and on land, this line features a black watch case symbolizing toughness, with accents in vivid emergency colors that capture the world of professionals involved in rescue efforts and other critical missions. Employing a structure resistant to dust, mud, vibration, and shock, the MUDMASTER GWGB1000EC delivers solar-powered timekeeping with Bluetooth® and radio control accuracy, Triple Sensor technology, and more.
The powerful design ensures durability and a comfortable fit thanks to an inventive combination of materials that includes carbon fiber-reinforced resin*1 and forged metals. Use the Location Indicator feature to see the direction of a target destination via an indicator hand on the watch. *1 Due to the characteristics of carbon fiber-reinforced resin, the pattern and color tone that appears on the surface will vary model by model.
