The Mudmaster GG-1000-1A3ER is considered by many to be the best G-Shock watch you can get. Designed specifically for professional users and is packed with features selected to make doing your job easier; Digital compass and thermometer to determine the conditions of your outdoor environment. The Super Auto-LED illumination of the face during low levels of light and Neobrite coating on the watch hands and index ensure an easy to read display when you need it most. But there's no point in having these features if you can't handle yourself in the field, again G-Shock have not disappointed; Shock-resistant construction guards against impacts and vibration from recoil, the mud-resistant case protects against mug and dirt from entering your watch and with a 200m water resistance rating it will not suffer in wet weather either. All in all, this is one tough watch that has obvious benefits to military, police and security users but also ideal for hiking, trekking, travelling, cycling and pretty much any other outdoor use. It also looks pretty damn cool so good luck trying to take it off in your social time.


If the ambient light fades, a turn of your wrist illuminates the watch display particularly brightly and in colour.


Shock-resistant construction protects against impact and vibration.
