Enjoy both fearless adventure and a comfortable fit with this tough and rugged Master of G Mudmaster flagship timepiece.

This analogue-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 fibre-reinforced resin case 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.

What to do with Broken Watches? 

G Shock Battery Replacement

G Shock battery life ranges from two to six years, depending on how often you use the alarm or the backlight. Frequent use of either feature drains the battery pretty fast hence, the need for replacement. The life of the replacement battery, on the other hand, depends on how long it has been sitting on the shelf. Its shelf life is ten years in room temperature after which it goes through gradual degradation.

G Shock Strap Replacement 

G Shock watches are known to last a lifetime, but the bands wear out after prolonged use. To replace them, place the watch facing downwards on a soft cloth, unhook the spring bars located at the base of each strap. Some models have the bars covered while others are exposed. Use a spring-bar removal tool to unhook and pull the band away from the watch. Repeat the process to remove the other spring bar. Replace them with the rod slots of the new band and use the spring-bar tool to fasten the bands. The procedure applies when replacing rubber straps. Metallic bands require a little tact hence, the need to engage a professional.
