G-Shock Master of G

Master of G is G-Shock built for one environment at a time. Mudmaster seals the buttons against grit and dust. Frogman is built around diving. Rangeman carries altimeter, barometer and compass. Mudman keeps it stripped back.

Expect solar charging, larger cases — many above 50mm — and the longest feature lists Casio makes. The GW-9400 Rangeman is the volume seller in this range and the sensible starting point if you are new to it.
