G-SHOCK Master of G — How Mudmaster, Rangeman and Frogman Differ

If you're seriously outdoorsy, the Master of G family is the G-SHOCK built specifically for hard use. This article sums up the differences so you pick the right one — browse all G-SHOCK alongside.
Mudmaster — mud and dust resistant
Designed for work that involves mud, dust and vibration, such as construction and off-roading. The buttons are sealed against mud and the large case is easy to grip.
Rangeman — a full sensor set for trekking
Stands out for its altimeter, barometer and compass sensors — ideal for trekking and climbing. Compare it with PRO TREK.
Mudman — the classic mud-resistant model
The original mud-resistant model: all-digital, simple and tough. For people who like a classic that can take a beating.
Frogman — for diving
Built specifically for diving, with high water resistance for serious water activities. Read more about ratings in how much water resistance a dive watch needs.
Tip: if you're not doing hard outdoor work every day, a regular G-SHOCK is already tougher than you need and lighter. Master of G models are for genuinely specialised use.

FAQ
Is Master of G more expensive than regular models?
Generally yes, because of the sensors and specialised materials — but they're tougher and have more functions to match.
Can I wear a Master of G every day?
Yes, but the cases are fairly large and thick, so they suit people who like a rugged look. For something smaller, look at the GA or DW models.
