Description:
The GWG-1000-1A3JF embodies the MASTER OF G MUDMASTER philosophy—a rugged, large-format outdoor chronograph engineered for extreme land expeditions and harsh terrain. Sized 59.5 × 56.1 × 18 mm, weighing 119 g, this model combines resin lower case with stainless-steel upper bezel in a distinctive two-tone construction that emphasizes tactical robustness. The flagship feature set includes Triple Sensor Ver. 2 (compass with continuous 60-second bearing measurement, altimeter-barometer with pressure-trend graphing, thermometer −10 to +60°C), enabling precise navigation, weather prediction, and altitude tracking in remote environments. Tough Solar + Multi-Band 6 provides autonomous operation—approximately 6 months on full charge, extending to 25 months in power-save mode. Anti-reflective sapphire crystal, mud-resistant construction with new Mud Resist structure, and shock-resistant design (hollow-case engineering) ensure durability against mud, dust, and vibration.
