G-Shock GWGB1000-1A4 Master of G Mudmaster Watch

$799.00

(1,645 reviews)

Enjoy both fearless adventure and a comfortable fit with this tough and rugged Master of G Mudmaster flagship timepiece. This analog-digital combination watch delivers more comfortable fit and outstanding durability with a robust exterior incorporating a guarding structure built with metal components. The watches of the G-SHOCK Master of G line, developed for professionals working in the harshest environments, come equipped with even tougher functionality. And the MUDMASTER takes this even further with the ability to handle the roughest on-land environments, earning the appreciation and trust of rangers and rescue teams operating in extreme environments. The comfortably sized GWG-B1000 features a metal exterior crafted with high-precision forging techniques and a carbon fiber-reinforced resin case*1 that offers high strength and outstanding durability. Radio-controlled and solar-powered, the watch is also equipped with a triple sensor that keeps you updated with direction, altitude, barometric pressure, and temperature readings. Double LED lights and sapphire crystal ensure high 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. The use of bio-based resins for the case, some bezel components, and the band make for a watch that demonstrates the MUDMASTER commitment to the environment. *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.
