Mud and shock-resistant, the G-Shock Mudmaster Watch provides you with accurate time, directional, barometric pressure, altitudinal, and temperature readings.

Casio’s solar-powered G-Shock Mudmaster Watch reliably operates in the harshest environments, from jungles to deserts. The cylindrical button guards, shafts, and pipes alleviate lateral shocks and provide airtight protection against mud, sand, and dirt. Air vents positioned in the base of the button shafts prevent button malfunctions due to changes in air pressure. The αGEL®-packed wristband protects the Mudmaster from malfunctions or damage due to vibrations, such as when operating cutters, drills, or other heavy machinery designed to clear away large obstacles. Illuminated by a double LED light and protected by a sapphire crystal, the Mudmaster’s watch face maintains high visibility under virtually any conditions imaginable. The watch face is marked with large Arabic numerals for easy reading and features hour and minute hands with points shaped like warning markers. The Mudmaster features Triple Sensor Version 3 capabilities, which provide instant access to directional, barometric pressure, altitudinal, and temperature information when needed under tough conditions. With its durable mud-resistant construction, easy to read watch face, and versatile sensor capabilities, Casio’s G-Shock Mudmaster Watch is ideal for army rangers and rescue crews.
