Casio - G-Shock, Carbon Fibre Mudmaster Quartz Watch GG-B100-1A3ER

Introducing the latest addition to the G-SHOCK MUDMASTER series.

Part of the specialist Master of G series designed for use in the most extreme conditions, our new GG-B100 watches feature the all-new Carbon Core Guard case, with a dust and mud-resistant structure that can withstand harsh land environments.

The GG-B100-1A3ER features a herringbone print, chrome finish bezel in black, completed with an army green resin strap. Dial details are highlighted in yellow, such as the location indicator at 12 o’clock, which displays the compass bearing direction and distance to a user-specified destination. A digital sub-dial at 6 o’clock details information such as day, date and month.

Equipped with an impressive range of tech features intended to support land missions, all sensors can be linked to a dedicated app for data capture and mission monitoring. The watch has a triple sensor and an accelerometer: the three sensors detect compass bearing, measure atmospheric pressure/altitude, and gauge temperature, while the accelerometer counts steps.

When paired with a smartphone, your watch automatically adjusts the time, and records mission logs, using altitude data from the watch and GPS data from the smartphone.
