Description
The Casio G-Shock GDG-B100-1 (cataloged within G-Shock’s specialized Master of G Mudman series) is an advanced, high-performance digital timepiece engineered to thrive in harsh environments laden with dirt, sand, and mud. Designed for field operations, trail athletics, and outdoor survival, this model combines rugged durability with eco-conscious manufacturing. Built around a Carbon Core Guard structure crafted from renewable bio-based carbon and bio-based resins measuring 63.6 × 49.6 mm in diameter and 16.2 mm in thickness, the watch offers an ergonomic, lightweight wrist presence at just 66 grams. It is secured by a flexible black bio-based resin strap fastened with a classic pin buckle.
The defining visual centerpiece of this GDG-B100-1 reference is its all-black tactical housing paired with an ultra-clear, high-contrast Memory-in-Pixel (MIP) LCD screen designed for effortless outdoor readability in direct sunlight or darkness. The digital display is shielded by a resilient mineral glass crystal.
Engineered for extreme durability and aquatic utility, the timepiece features a certified 20-bar (200-meter) water resistance rating, shock resistance, and a specialized mud-resistant gasket-and-cylinder button structure that prevents particles from infiltrating the internal module. Powered by a quartz movement utilizing a CR2032 battery with an approximate 2-year lifespan, it features Smartphone Link via Bluetooth for auto-time calibration, accelerometer-driven training functions (speed, pace, distance, and calorie expenditure tracking), a 1/100-second stopwatch, countdown timer, multiple alarms, and Life Log activity monitoring. Blending signature G-Shock toughness, bio-based sustainability, and specialized land-mission capabilities, the Casio G-Shock GDG-B100-1 stands out as an exceptional instrument for demanding outdoor adventures.
