Description

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. 

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. 

Features

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
