Casio’s HUD: G-SHOCK GRAVITYMASTER GRB300-8A2 Pilot Watch


Just as the Head-up Display (HUD) is an icon of innovation in aviation history, the G-SHOCK GRAVITYMASTER series of pilot watches is an icon of innovation in timepieces designed for performance in flight with an aviation aesthetic. Casio has a passion for aviation, and the G-SHOCK GRAVITYMASTER GRB300-8A2 pilot watch is that passion made manifest. With a gray/blue design modeled after a HUD, the innovative bezel and triple-layer dial combine to fashion a pilot watch that looks molded from a cockpit itself.

Next-generation aircraft sport seamless-edge designs, and the bezel and case of the GRAVITYMASTER GRB300-8A2 pilot watch utilize that seamless-edge concept. The nonstandard bezel couples with a triple-layer dial to create a 3-D watch face with raised indices. The blue accents on the indices and hands craft an effect like a HUD. Taken altogether, the watch face is a cinch to read, giving you the critical information you need at a glance.

Aviation demands advanced instrumentation, and the G-SHOCK GRAVITYMASTER GRB300-8A2 pilot watch provides it. The GRB300-8A2 sports a dual-time feature, allowing you to keep track of time in two locations. The rotary battery-level indicator at the 9-o’clock position and the mode indicator at the 12-o’clock position grant you the tactical advantage of gleaning information quickly and easily. Bluetooth® connectivity with a smartphone auto-adjusts the time four times a day for impeccable accuracy, and Tough Solar charging ensures this aviation watch is reliable.

A Carbon Core Guard structure outfits the watch with a carbon-fiber resin used in aircraft fuselages, and G-SHOCK shock resistance and 200m water resistance make this the toughest pilot watch in the skies. A Super Illuminator LED light gives you an excellent read no matter the lighting condition. This is an aviation watch that truly continues the legacy of the G-SHOCK Master of G line.
