Push your limits with a MASTER OF G watch, made for professionals facing demanding conditions. The MASTER IN HORIZON GOLD collection draws inspiration from the golden line where earth meets sky. A light yellow gold ion-plated metal bezel and brown ion-plated accents pair with a dark brown resin band, bringing refined style and a rugged, nature-inspired look.

Built with a shock-resistant Carbon Core Guard structure, the GRB300H-5A combines a carbon fiber-reinforced resin case with a seamless bezel design inspired by next-generation aircraft. Dual-time switching makes it easy to move between home and local time while traveling. Large raised indexes and a prominent metal bezel support clear, intuitive time reading. At 9 o’clock, a dual-coil motor drives the rotary disc indicator, which displays alarm status and also serves as a stopwatch and battery level indicator.
