GR-B300H-5A

Expand your horizons with a MASTER OF G — designed for pros working in the toughest of environments. Take the first step in a journey of endless exploration with the MASTER IN HORIZON GOLD, inspired by the golden horizon where earth meets sky. This is one tough watch built to deliver with refined style and rugged performance. The design features a metal bezel finished in light yellow gold ion plating and key metal components accented with brown ion plating. Paired with a dark brown resin band, these timepieces project the awe-inspiring power of nature. The GR-B300H-5A employs a shock-resistant Carbon Core Guard structure with carbon fiber-reinforced resin case and seamless bezel design inspired by next-generation aircraft, coming together in a bold and powerful form. Dual-time instantly switches between the time back home and local time, a practical function to make traveling abroad that much smoother. The large, raised indexes and metal bezel accentuating the large watch face enhance the visibility and functionality so important for pilots, whose job demands intuitive reading of time. The rotary disc indicator at the 9 o’clock position is driven by a dual-coil motor to ensure smooth rotation and functional beauty, rotates to display alarm on/off status, serves as stopwatch, and also functions as a battery level indicator.
