Casio has a passion for aviation and the G-SHOCK Gravitymaster pilot watch is that 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 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. Aviation demands advanced instrumentation and the G-SHOCK Gravitymaster 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-oclock position and the mode indicator at the 12-oclock 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. 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 an excellent read no matter the lighting condition.
