Strokes of brilliant sunlight cool into wispy deep orange and fade into the purple of night above a summer cloud deck at 15,000 feet. Switching on the instrument panel lighting, you turn down the brightness of the orange glow so that it matches the low-level of ambient light outside the aircraft. Glancing at your G-SHOCK GRAVITYMASTER GRB300-1A4 pilot watch tells you that your destination city time is 2200, and the dual time feature shows your departure city time was 1800. You’ve reached cruising altitude, and there’s plenty of flight time left.

Aircraft pilots understand the need for accurate timekeeping, and the G-SHOCK GRAVITYMASTER GRB300-1A4 pilot watch connects to your smartphone via Bluetooth® to automatically adjust the time, keeping your pilot watch reliably accurate.

Modeled after the look of a nighttime cockpit, the orange accents of the G-SHOCK GRAVITYMASTER GRB300-1A4 pilot watch evoke instrument panel lighting, while the dials on the face of the watch evoke the classic look of aircraft instrumentation. The combination of a triple-layer dial to craft a 3-D watch face with accents of orange on the indices, face, and select hands, make the GRB300-1A4 easy to read at a glance. The Super Illuminator LED light ensures that the pilot watch can be read no matter the level of lighting.

Inspired by the smooth lines of next-generation aircraft, Casio was able to craft a seamless edge to the intricately-shaped bezel. Built G-SHOCK tough, the case is made with carbon fiber-reinforced resin which gives the pilot watch case its strength and lightness. This pilot watch is also 200m water resistant (wr 20 bar), adding another level of protection and durability. Casio’s G-SHOCK Master of G line of watches glory in a reputation for legendary toughness, and the GRAVITYMASTER GRB300 pilot watch series takes that toughness to the skies.
