    Gravitymaster GRB300-1A

    The sky’s the limit! Introducing the GRAVITYMASTER GRB300, a piece of aviation-inspired professional gear designed to work even in the harshest environments, from the G-SHOCK MASTER of G line.

    The GRB300 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.
