Description

The GRAVITYMASTER GR-B300, an aviation-concept watch from the G-SHOCK MASTER OF G series, is designed for professionals working in harsh environments. The GR-B300 is a GRAVITYMASTER watch featuring a shock-resistant "Carbon Core Guard" structure, taking advantage of the properties of carbon material (impact resistance, rigidity, and resistance to deterioration), also used in aircraft bodies. The combination of a carbon fiber-reinforced resin case and a seamless bezel inspired by next-generation aircraft creates the powerful form of a GRAVITYMASTER. Designed for flight recording, the watch features a Flight Log function that records your current location and time, and Dual Time, which simultaneously displays the time in two time zones, evoking the world of aviation and pilots. In addition to the Home Time Swap function, which allows you to instantly switch between the Home Time city and the Local Time city with the tap of a button in the app, the Dual Time function allows you to simultaneously display the time in two cities, making it useful for international travel. To ensure legibility, which is crucial during flights, where intuitive reading is essential, the watch features large, three-dimensional hour markers and a metal bezel that accentuates the wide face, enhancing its functionality. The disc hand at 9 o'clock is driven by a dual-coil motor, enhancing the movement and functional beauty of the hand. In addition to rotating functions such as the alarm on/off function and stopwatch, it also serves as a battery indicator. The dial and buttons feature high-contrast accent colors found in aircraft cockpits, while the design features a functional dark color variation. The case, bezel, and band are made from biomass plastic, which is expected to reduce environmental impact. Time adjustment via Bluetooth® connection ensures the time accuracy required for aviation missions, and solar power provides practicality. This GRAVITYMASTER embodies the worldview of professional aviation and the "longing for the sky," while supporting tireless challenges to the limits.
