"This is the much anticipated update to the Mudman, part of the Master of G series. This watch is primarily named because its stainless steel and resin case is designed to be mud resistant, as well as the usual G-Shock trademark toughness. In addition, it now features a twin sensor, so this gives the added functionality of an electronic compass and thermometer.
The movement is Tough Solar, so is recharged by natural and artifical light. The watch has a perpetual calendar, stopwatch, alarm, countdown timer, as well as world time function. The backlight is a Dual Illuminator, so perfect for dealing with low light conditions. "@en
