Conquer tough terrain and grab attention with a rugged timepiece boasting a bold, eye-catching color 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 GGB100 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 construction to protect against mud, a stainless steel panel back, and a back cover made of shock-resistant fine resin embedded with glass fibers, giving it a high level of resistance to dust and mud. The bezel also uses three layers of fine resin with carbon fiber inserts. This tough, rugged design is accented in bright bold yellow.
