Description
CASIO GG-B100XM-1AER is a powerful men’s analog-digital watch from the Master of G Mudmaster series, built for extreme conditions and professional fieldwork. The black design paired with a silver stainless steel bezel featuring a honed matte finish provides excellent resistance to scratches, mud, and dust, while the red seconds hand adds a confident sporty accent. The carbon fiber-reinforced resin case (Carbon Core Guard) combines lightness, strength, and exceptional shock resistance — which is why this watch is trusted by rangers and rescue teams operating in the harshest environments.
The 55.4 × 51.3 × 19.4 mm case is made of carbon fiber-reinforced resin with a stainless steel bezel and complemented by a black silicone strap. The model features a quartz movement (Module 5594) with a Quad Sensor (compass, barometer, altimeter, thermometer) and smartphone link functionality.
