G-SHOCK MASTER OF G - TERRA MUDMASTER, 51MM - GG-B100Y-1AER

Take on even the toughest challenges and turn heads with an extremely durable watch featuring a bold and eye-catching color scheme. The new MASTER OF G marks a new level of technological evolution, enhanced by a rugged design with yellow accents, a hue typically used for emergency response. The GG-B100 MUDMASTER's case is made of carbon fiber to ensure an extremely high level of shock resistance. This watch also features a special filter that protects against mud ingress, a stainless steel back panel, and a shock-resistant fine resin backing embedded with glass fibers, giving it a high level of dust and mud resistance. Three layers of fine resin with carbon fiber inserts have also been used for the bezel. This rugged and durable design is enhanced by a bright yellow color. Practical and functional, this watch is equipped with a digital compass, altimeter/barometer, thermometer, and pedometer. In addition to easy time adjustment with the dedicated G-SHOCK app, many other useful functions are available, including the mission log, which automatically records altitude data acquired by the watch and route data acquired by the smartphone.
