Watch Description
Watch Description
The Casio G-Shock GWG-B1000-1A3 (widely known in regional markets as the GWG-B1000-1A3JF) is a pinnacle professional analog-digital tactical timepiece engineered for elite survivalists, rescue workers, and outdoor adventurers operating in extreme muddy, dusty, and rugged environments. As a flagship model within G-Shock's prestigious Master of G LAND Series, the Mudmaster combines uncompromising physical toughness with cutting-edge sensor technology. Across international tactical gear forums and watch collector communities, it has earned defining community nicknames—the "Olive Green Mudmaster", "Carbon Core GWG-B1000", "Bluetooth Mudmaster Green", or simply the "GWG-B1000 Green". It earns these names for its tactical olive green bio-based resin strap, mud-resistant cylindrical button guards, carbon fiber-reinforced case structure, and multi-sensor capabilities. It unites a shock-resistant and mud-resistant architectural case measuring 52.1mm in width (58.7mm lug-to-lug) with a high-contrast analog-digital face, scratch-resistant sapphire crystal glass, an in-house Japanese solar-atomic Bluetooth engine, and an integrated durable resin strap. Weighing a substantial 114.0 grams, it is meticulously calibrated for professionals who demand absolute precision and indestructible reliability in the most hostile terrains.
The defining visual centerpiece of this GWG-B1000-1A3 reference is its Tactical Olive Green Livery and Forged Stainless Steel Bezel Armor. The stainless steel bezel features a complex multi-piece construction treated with a durable dark ion plating (IP) and protective guards, contrasted by shock-absorbing resin components in a deep military olive green tone. The dial layout combines high-visibility analog hands with a clear digital LCD screen, featuring a front button and metal-accented markers designed for high-grip operation even while wearing thick rescue gloves. Turning the watch over reveals a solid screw-lock caseback stamped with the iconic Mudmaster mole emblem and technical specifications.
Beneath its rugged exterior, the watch is driven by Casio’s advanced in-house Japanese solar-atomic multi-sensor engine. Equipped with Multi-Band 6 atomic timekeeping, the watch automatically receives calibration radio signals from six transmission stations worldwide (covering Japan, North America, UK, Germany, and China) to guarantee absolute split-second accuracy. Power management is handled by Casio’s proprietary Tough Solar technology, which converts natural sunlight and ambient indoor lighting into electrical energy stored in a secondary rechargeable battery, entirely eliminating periodic battery changes.
Punctuality and outdoor mission logging are enhanced by an energy-efficient Bluetooth Mobile Link system. By pairing wirelessly with the CASIO WATCHES smartphone application, the watch unlocks advanced tactical features including the Mission Log (recording waypoint locations and travel tracks on your phone map), Location Indicator (showing the bearing and distance to a previously recorded destination), and automatic time correction.
The case is engineered with commanding, robust proportions, measuring an official 58.7mm in case length (lug-to-lug), 52.1mm in case width (diameter), a heavy-duty thickness of 16.2mm, and a total weight of 114.0 grams. Dial protection is provided by high-grade, scratch-resistant sapphire crystal glass with an anti-reflective coating. Engineered for extreme aquatic and outdoor survival, the case secures a certified 20-bar (200 meters / 660 ft) water resistance rating, making it completely safe for swimming, heavy water exposure, and survival conditions. The watch comes fitted with a comfortable olive green bio-based resin strap fastened with a stainless steel pin buckle.
