Watch Description
Watch Description
The Casio G-Shock GDG-B100-1A5 (part of G-Shock’s Master of G Mudman series) is a purpose-built digital tool watch engineered for harsh land environments plagued by dust, sand, and mud. Designed with an off-road bumper-guard aesthetic, this reference pairs a black multifaceted protective bezel with warm desert-sand and muted orange strap styling. Built around a Bio-based Carbon Core Guard structure measuring 63.6 × 49.6 mm across and 16.2 mm thick, it weighs just 66 grams for comfortable long-term field wear. It fastens securely with a flexible bio-based resin band and a pin buckle.
The centerpiece of the GDG-B100-1A5 is its high-definition Memory-in-Pixel (MIP) LCD, offering sharp readability under direct sunlight and dark environments. Nighttime visibility is supported by an auto red LED backlight designed to preserve natural night vision. On the case back, you'll find the iconic MUDMAN mole character engraved in high relief.
Engineered for extreme reliability, it features 20-bar (200-meter) water resistance, shock-proof armor, and gasket-sealed button cylinders to stop grit from penetrating the module. Powered by a CR2032 battery with about a 2-year lifespan, it links to your smartphone via Bluetooth for automatic time calibration and phone alerts. An onboard accelerometer tracks steps, distance, speed, pace, and calories, storing up to 100 activity runs. It rounds out with 38-city world time, interval timers, a 1-second stopwatch, and vibration alarms, making the GDG-B100-1A5 a rugged companion for demanding outdoor work and adventures.
