Conquer tough terrain and grab attention with a rugged timepiece boasting a bold, eye-catching colour scheme.

Designed to work even in the harshest environments, MASTER of G specialty watches take timekeeping to new heights with a rugged design accented in the bright yellow used for emergency rescues. The GG-B100 MUDMASTER employs high rigidity carbon in the case to keep damage and warping at bay and ensure extreme airtightness and shock resistance.

This timepiece also features a filter to protect against mud, a stainless steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibres, giving it a high level of resistance to dust and mud. The bezel also uses three layers of fine resin with carbon fibre inserts. This tough, rugged design is accented in bright bold yellow. Practical and functional, this watch is equipped with digital compass, altimeter/barometer, thermometer and step counter.

Easily correct the time using the dedicated G-SHOCK app, and tap into loads of other useful features including the Mission Log, which automatically records altitude data obtained from the watch and route data obtained by your smartphone.
