G-SHOCK MASTER OF G Series GRAVITYMASTER GR-B300

– The aviation concept GRAVITYMASTER GR-B300 is from the G-SHOCK MASTER OF G series for professionals operating in harsh environments.

– The GR-B300 features a shock-resistant structure that takes advantage of the characteristics (impact resistance, rigidity, and degradation resistance) of carbon material, which is also used in aircraft fuselages.
The GRAVITYMASTER uses the Carbon Core Guard Structure, a shock-resistant structure that takes advantage of the characteristics of carbon material (impact resistance, rigidity, and deterioration resistance) also used in aircraft.
By combining a case made of carbon fiber reinforced resin with a seamless bezel inspired by next-generation aircraft
GRAVITYMASTER’s powerful form has been realized.

– The flight log function allows the wearer to record the current position and time of the flight,
The dual time display function, which can simultaneously display the time in two time zones, creates a world view of aircraft and pilots.

– In addition to the Home Time Switch function, which allows users to instantly switch between their home time city and local time city with the tap of a button on the application, the Dual Time function allows users to display the time in two cities at the same time,
Dual time is useful when traveling abroad, as it can display the time in two cities at the same time.

– In addition to the large, three-dimensional hour markers, which ensure legibility, an important feature when flying, where intuitive legibility is required,
In addition to the large, three-dimensional hour markers, a metal bezel is used to emphasize the wide face, enhancing the sense of functionality.
In addition, a dual coil motor is used for the disk hand at 9 o’clock to enhance the movement of the hand and functional beauty.
In addition to the rotating expression of the alarm on/off function and stopwatch, it also serves as a battery indicator.

– While high-contrast point colors seen in aircraft cockpits are used on the dial and buttons,
The design features dark color variations with a sense of functionality.

– The case, bezel, and band are made of biomass plastic, which is expected to reduce environmental impact.
The time correction by Bluetooth(R) connection ensures the time accuracy required for aviation missions, and the solar power operation is also practical.

– The GRAVITYMASTER embodies the world of professional aviation and the yearning for the skies, while supporting the insatiable challenge to the limit.
