Casio G-Shock Mudmaster watch, black and green, GG-1000-1A3ER

Black and green Casio G-Shock Mudmaster watch with compass, thermometer and mud-resistant construction

What sets this Mudmaster watch apart from other G-SHOCKs is the cylindrical button guard, which keeps fine sand, dust and mud out of the buttons. The case is 56 mm wide, made of black plastic and stainless steel, and the strap is textured olive green resin. The dial has analog hands and a digital display. Large Arabic numerals and wide hands keep the time easy to read, and the hands and indexes have Neobrite luminous coating. The design has a military feel.

With the Twin Sensor functions, the watch shows direction and temperature. The mechanical second hand of the digital compass turns to point north, and the thermometer range is -10 °C – +60 °C. The watch also has world time, a stopwatch, a timer, 5 daily alarms and an LED light that turns on when you raise your wrist. Water resistance is 200 m / 20 atm: the watch is suitable for swimming, water sports and snorkeling, but not for scuba diving, because the dial has no Diver's marking. The battery of the quartz movement lasts about 2 years. The history of G-SHOCK begins in 1983, when Kikuo Ibe developed the DW-5000C model.
