G-SHOCK GG-B100X-1A - MUDMASTER
A quad sensor is four instruments in a watch that also has to survive being dropped in a trench.
The GG-B100X is a MUDMASTER, part of G-SHOCK's Master of G family, and this generation adds Carbon Core Guard and a carbon fibre bezel to the mud-resistant construction. The result is a 19.4 mm deep watch that weighs 93 grams, which for this much instrumentation is genuinely light.
All black, in a case 55.4 by 51.3 mm, under a spherical mineral crystal that curves rather than sits flat. Module 5744 runs compass, altimeter, barometer and thermometer, plus step tracking, world time, a stopwatch, a countdown timer and alarms, and links to the CASIO WATCHES app over Bluetooth. Neobrite on the hands and markers. 200 m water resistant.
The most capable MUDMASTER that runs on a standard battery. Reads everything and asks for nothing.
Perfect for: quad sensor MUDMASTER watches, compass altimeter watches, carbon fibre Master of G watches.
