This rugged design from the G-Shock MASTER OF G Series, the MUDMASTER makes sure that nothing gets into the watch when work gets dirty. Multiple gaskets are used on the pipes that guide buttons and shafts, which keeps mud out. In addition, quad sensor capabilities provide instant access to thermometer, altimeter/barometer, digital compass and step counter information when needed under tough conditions. The 55mm case houses the black dial which is marked with large Arabic numerals at 12, 3, 6, and 9 o'clock for easy reading and is illuminated by a Super Illuminator, high-brightness auto LED light to ensure high visibility under virtually any condition. The green rubber strap is processed to resemble a cloth band texture, and the hour and minute hands are shaped with points that make them resemble warning markers. The watch is shock-resistant, mud-resistant and water-resistant to 200m.
