From the G-SHOCK MASTER OF G series for professionals working in harsh environments, it is the GRAVITYMASTER GR-B300 with an aeronautical concept. The GR-B300 is a GRAVITYMASTER that uses an impact-resistant “carbon core guard structure” that makes use of the characteristics (impact resistance/rigidity/deterioration resistance) of carbon materials also used in aircraft fuselages. By combining a case using carbon fiber-reinforced resin with a seamless bezel inspired by next-generation aircraft, we have achieved a strong form as a GRAVITYMASTER. Assuming flight time recording, the world view of aircraft and pilots is created with a flight log function that can record the current position and time, and dual time, which can simultaneously display the time in the two time zones. In addition to the home time time replacement function that allows you to instantly switch between home time cities and local time cities by simply tapping a button on the app, it is equipped with a dual time that can simultaneously display the time of the two cities, which is useful when traveling abroad, etc. In order to ensure important visibility during flights where intuitive reading is required, in addition to large, three-dimensional time characters, a metal bezel that emphasizes a wide face was adopted to enhance the sense of functionality. Also, by adopting a dual coil motor for the disc needle on the 9 o'clock side, it pursues needle movement and functional beauty. In addition to the ON/OFF function of alarms and rotation expressions such as stopwatches, etc., it also plays a role as a battery indicator. While the high-contrast point colors seen in aircraft cockpits are placed on the dial and buttons, they are designed in a variety of dark colors with a sense of functionality. Biomass plastic, which is expected to reduce environmental impact, is used for the case, bezel, and band. Time accuracy required for aviation missions was also ensured by time correction via Bluetooth® connection, and practicality with solar power was also pursued. GRAVITYMASTER embodies the professional world view of aviation and “longing for the sky,” while supporting the insatiable challenge to the extreme.
