The Mudmaster Pro GG-B100XM-1AER is a G-SHOCK in which the black bio-based resin section is surrounded by a matte, silver-coloured stainless steel bezel. The bezel protects against mud and dust, and it has visible screws at the corners. The case is 51.3 mm wide and 19 mm thick, so the watch is large. The black bio-based resin strap fits wrists of 145–215 mm. G-SHOCK, started by Kikuo Ibe in 1983, is built on durability.

The dial has an analog and a digital display. The watch has a digital compass, an altimeter and barometer, a thermometer and a step counter. The mission log records altitude data from the watch and route data from a smartphone via a Bluetooth connection. The hands and hour markers are luminous, and the watch also features world time, a stopwatch and five alarms. Water resistance of 200 m / 20 atm is sufficient for swimming, water sports, snorkeling and free diving, but not for scuba diving.
