Overview The power and beauty of nature encased in rugged shock-resistant construction. Introducing the very special “Magma Gold” MUDMASTER, from the flagship line of the celebrated MASTER OF G. Thanks to a high-precision forged metal shield outer shell and Carbon Core Guard structure, the smaller profile GWG-B1000MG ensures outstanding durability as well as a comfortable fit. Combining the lightness of carbon fiber-reinforced resin with the toughness of metal, this design delivers reliable performance capable of withstanding extreme environments. The indexes and watch hands project intense red and orange hues inspired by the crimson orange of flowing magma and landscapes that turn golden yellow as magma solidifies. Metal components finished with ion-plating in multiple shades of gold highlight the structural beauty of layered golden hues. Garal color molding combines resin in different colors to create marbled patterns on the band, evoking the Earth’s majestic layers. Made with bio-based resin, the case exudes strength and solidity, while honoring the MUDMASTER commitment to the environment. Magma Gold embodies “beauty in toughness,” a stunning and rugged watch that endures the harshest environments. Radio-controlled and solar-powered, the watch is also equipped with Triple Sensor to keep you updated with direction, altitude, barometric pressure, and temperature readings. Double LED lights and sapphire crystal ensure reliable readability so you always see the time and other readings, no matter what the conditions are like. Input a specific location in the app and the Location Indicator function moves the indicator hand at the 3 o’clock position to point in that direction so you stay on track at all times — even when visibility is obstructed by extreme conditions like sandstorms.
