The sky’s the limit! Introducing the GRAVITYMASTER GR-B300, a piece of aviation-inspired professional gear designed to work even in the harshest environments, from the G-SHOCK MASTER of G line. The GR-B300 features a Carbon Core Guard structure, which delivers the shock-resistance, rigidity, and corrosion-resistance of carbon material used in aircraft fuselages. The carbon fiber-reinforced resin case and the seamless bezel design inspired by next-generation aircraft come together in a bold and powerful form. Envision the world through a pilot’s eyes with the flight log memory function for recording current location and time, as well as dual-time simultaneously displaying the time in two time zones. In addition, simply tap on the app to instantly switch between the time back home and local time — a practical function to make traveling abroad that much smoother. Large, dimensional index marks and a metal bezel accentuating the large watch face exude functionality, enhancing the visibility that is so important for pilots, whose job demands intuitive reading of time. The rotary disc indicator at the 9 o’clock position uses a dual-coil motor to ensure smooth rotation and functional beauty. The indicator not only rotates to display alarm on/off and stopwatch; it functions as a battery level indicator as well. The high-contrast black and white color scheme dotted with color accents on the dial and buttons evokes the look of a cockpit instrument panel, while dark color variations express the practical functionality of an aviation worldview. Key resin components used in the case, bezel, and band are made with bio-based resin, a material expected to help reduce environmental impact.

Seamless design offering functional beauty

An organic form inspired by
next-generation aircraft is expressed with the seamless exterior design. A sense of unity is achieved by connecting the exterior surfaces, from the case to the band, smoothly and seamlessly. This design creates a tough, cutting-edge look, seemly for a new addition to the GRAVITYMASTER line.

3D face design for enhanced readability

The large-diameter, triple-layer dial
with a sense of depth ensures readability for pilots, whose job demands intuitive reading of time. In addition to large, dimensional index marks and inset dials inspired by instrument panels, the metal bezel
accentuating the large watch face ensures this design exudes functionality.

Dual time: Simultaneous display of time in two cities

The main dial and inset dial simultaneously display times in two cities located in different time zones. A dedicated app makes it easy to configure world time settings. Switching between home time and world time is a snap, as well. This watch puts accurate time management just a fingertip away.

Colouration evoking the look of a cockpit

A high-contrast black and white colour
scheme enhances the visibility of the watch hands and index marks, components responsible for the most vital watch functions. Red and blue colour variations are offered as well, with the red model inspired by the display colour of a cockpit instrument panel’s nighttime illumination, and the blue, that of a head-up display (HUD). These distinctive combinations of colour deliver practical functionality expressing an aviation worldview.

Layer Guard and Carbon Core Guard structures: Featuring innovative combinations of materials

The intricately shaped bezel employs integrated moulding and has two rings — a metal ring and a urethane ring — installed beneath it. This combination of materials
gives the bezel — a structural component — a refined visual presence that embodies the intricacy and sophistication of next-generation aircraft. The case is made with carbon fibre-reinforced resin, a material delivering both strength and lightness. The side buttons have anti-slip texturing inspired by hazard warning stripe tapes, and the
guards beneath the buttons have been eliminated for even better operability.

Rotary disc indicator: Offering display for multiple functions

The rotary disc indicator at the 9
o’clock position uses a dual-coil motor to ensure smooth rotation. It
indicates battery level and alarm on/off status, as well as displaying
motion linked to each mode.

Flight log: Helpful for flight history management

Sync the watch with a smartphone and press a button on the watch to record the current time and position on a map within the dedicated app — a useful function for managing flight logs with details including times and locations of departure and
arrival. In addition, plotted data can be grouped for batch management of travel record details including points of departure, transit points, and home destinations.

*This app is currently in development, and specifications are not yet final.

Attention to materials: Bio-based resin
