G-Shock Mudmaster Watch. GGB100-1B - The "Stealth" Ground Force

The GG-B100-1B is a study in Environmental Hardening. Its standout feature is the Carbon Core Guard structure combined with a Triple-Layer Carbon Fiber Insert Bezel. This creates a "monocoque" casing that is incredibly lightweight yet effectively "unbreakable."

The "Mudmaster" name comes from its specialized cylindrical button structure with dual-gasket seals, ensuring that even if you are submerged in thick sludge or fine desert sand, the internal sensors and movement remain untouched.

Key Performance Features

Quad Sensor Technology: Features a Compass, Altimeter/Barometer, and Thermometer, plus a Step Tracker (Accelerometer) for a complete picture of your physical activity and environment.

Carbon Fiber Reinforced Case: A high-tech material that offers the strength of steel with the weight of resin, featuring a visible carbon fiber weave in the bezel.

Smartphone Link (Bluetooth®): Pairs with the G-SHOCK app to record your Mission Log (altitude and GPS location points from your phone) and a "Location Indicator" to help you navigate back to a saved point.

Mud-Resistant Construction: Specialized gaskets and a "pipe" structure around the buttons prevent mud and dust from entering the case.

Calorie Consumption Tracker: Uses the step counter and altimeter data to calculate calories burned during a trek or mission.

Super Illuminator (Double LED): High-intensity LEDs illuminate both the analog face and the digital display for surgical clarity in the dark.

200m Water Resistance & Vibration Resistance: Built to handle the heavy vibrations of power tools, off-road vehicles, and heavy machinery.
