G-Shock Mudmaster Carbon Core
Triple-sensor Mudmaster with Bluetooth and solar power.
Our take on the G-Shock Mudmaster Carbon Core
The Mudmaster line exists for people who work in dust, mud and vibration — construction, rescue, motorsport. The GWG-B1000 adds carbon core guard construction and triple sensors, making it the most capable analogue G-Shock you can buy without moving to the MR-G tier.
What to know before buying
- ▸Triple sensor: compass, altimeter/barometer, thermometer.
- ▸Mud and dust resistant sealed construction with 200m water resistance.
- ▸Tough Solar plus Multi-Band 6 radio and Bluetooth sync.
- ▸Carbon core guard case — lighter and stiffer than resin alone.
Where and how to buy
Casio's own store and outdoor retailers carry the range. Older Mudmaster generations sell at heavy discounts and lose little practical capability if the sensor set matters more than the newest case material.

G-Shock Mudmaster Carbon Core — frequently asked questions
Is the Mudmaster good for hiking?
Yes — the altimeter, barometer and compass make it one of the better analogue trail watches, and solar charging removes battery worry.
How accurate is the altimeter?
It is barometric, so it drifts with weather. Calibrate at a known elevation for best results.
