Built for extreme terrain

The Casio G-SHOCK Master of G Land Mudman GW-9500-1A4 is a solar-powered digital watch with a mud-resistant structure and triple sensors. It is designed for professionals who operate in harsh environments where shock, dust and water are constant threats. The carbon core guard case and bioresin construction deliver 200 metres water resistance.

Check wrist fit and sensor needs

The case measures 56.7 by 52.7 by 14.8 millimetres and weighs 81 grams, so verify that the dimensions suit your wrist and any gear you wear over the cuff. Confirm you require the full triple-sensor suite — compass bearing memory, altimeter recording and barometer trends — because simpler models exist if only timekeeping is needed. The bioresin strap uses a buckle clasp; ensure that closure style works with gloves.

Replaces basic digital or analogue field watches

This model upgrades from standard shock-resistant watches that lack sensor logging or mud-sealed buttons. The jump is worth it when you need 30 altitude records, 14 walking-path logs, 60-second continuous compass measurement and magnetic declination correction in a single instrument. It is not for buyers who only want a daily-wear timepiece without navigation or environmental data.

Questions about this item

What comes in the box and does anything need to be bought separately?

The watch ships with the Bioresin case and strap fitted, mineral crystal, buckle clasp and Tough Solar charging built in. No separate charger or band is required.

Which version or capacity should I choose for this MUDMAN?

This reference GW-9500-1A4 is a single specification — black digital dial, 56.7 × 52.7 × 14.8 mm case, 81 g weight, 200 m water resistance and triple sensor suite.

What does the 200 m water resistance mean in daily use?

It is rated for 200 metres waterproof, suitable for swimming, snorkelling and surface water sports, but not for scuba diving. The mud-resistant button shafts and gaskets also keep out dirt and debris.
