Take to the skies with confidence: fly with a G- SHOCK GRAVITYMASTER GRB300 pilot watch. 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.

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.

The rotary battery-level indicator on the 9-o’clock side of the face beautifully incorporates every detail into the cockpit design scheme of this pilot watch. Design is key to aviation superiority, and the black GRAVITYMASTER GRB300-1A pilot watch is designed to mirror the smooth instrument reading of a cockpit.
