Introducing the latest addition to the MASTER OF G Series MUDMASTER, the G-Shock Master Of G Mudmaster Bluetooth Watch GGB100-1A3. This watch is specially engineered to withstand harsh land environments, making it your ultimate outdoor companion.

Superior Durability

The watch is constructed with a high-rigidity carbon material case, ensuring it stands up to damage and deformation from impact and rough treatment. This is further reinforced by metal button pipes for a tighter seal against external elements. A filter adds an additional layer of protection against dust and mud, making it ideal for use in severe environments.

Innovative Dual Back Cover Design

It features a dual back cover design comprising a stainless steel panel back and an outer cover made of shock-resistant fine resin embedded with glass fibers. The bezel is formed of three layers of fine resin with carbon fiber inserts for added strength.

Quad Sensor Capabilities

  • Compass
  • Altitude/Barometer
  • Temperature measurements
  • Accelerometer for step count

The Quad Sensor capabilities provide you with all the necessary data to monitor your surrounding environment on your outdoor adventures. The watch also facilitates consumed calorie calculations considering up and down grades, and records the results in an activity log.

Special G-SHOCK App

The watch comes with a special G-SHOCK app which records altitude data measured by the watch and route information sourced from your smartphone's GPS. With this app, you can also record your current location and the watch will indicate the bearing and distance to that location.

Mode Switching Customization

The GGB100-1A3 supports Mode Switching Customization, allowing you to enable or disable modes individually so only your preferred modes appear. You can even specify the sequence in which the modes are displayed.

Choose the G-Shock Master Of G Mudmaster Bluetooth Watch GGB100-1A3 for a durable, reliable and high-performing outdoor watch!
