Inspired by next-generation aircraft, the seamless bezel design combined with a case made of carbon fiber reinforced resin creates a powerful and distinctive GRAVITYMASTER look. Features like the Flight Log function for recording location and time during flights, and the Dual Time display for showing two time zones simultaneously, enhance the aviation theme and pilot experience. With intuitive readability essential for aviation, the watch features large, three-dimensional hour markers and a wide face emphasized by a metallic bezel, enhancing functionality. The use of a dual-coil motor for the 9 o'clock side hand ensures precise movement and aesthetic appeal. The watch also offers practical functions like alarm ON\/OFF, stopwatch, and a battery indicator. The design incorporates high-contrast colors reminiscent of aircraft cockpits on the dial and buttons, while maintaining a functional dark color scheme. The use of biomass plastic in the case, bezel, and band contributes to environmental sustainability. By enabling Bluetooth® connectivity for time correction and ensuring time accuracy required for aviation missions, along with solar-powered functionality, the GR-B300 GRAVITYMASTER supports relentless challenges towards the ultimate goal while embodying the world of professional aviation and the allure of the skies.\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\"
