GR-B300-1ACR

MASTER OF G-AIR
GRAVITY MASTER
GRB300-1A

Glancing at your G-SHOCK GRAVITYMASTER pilot watch, you see you left your departure city an hour ago, and the dual time indicates your arrival city is five hours ahead--plenty of time to work through your next maneuver. The large numerals “6” and “12” and the 3-D indices on the face of the G-SHOCK GRB300-1A pilot watch were designed for quick readability, making the glance you gave your watch all that was needed to maximize your focus and attention during flight.

The mode dial at the top of the watch face makes it easy to distinguish which function your pilot watch is performing. Timekeeping mode is on the right side of the dial and displays the day of the week, Sunday through Saturday. In Stopwatch, Timer, or Alarm mode, the hand points to mode abbreviation indices. The bezel design is modeled after next-generation aircraft with a seamless edge, and the triple-layer dial construction creates a wide 3-D face that makes this pilot watch a cinch to read. 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.

Built to withstand all the rigors of flight, the G-SHOCK GRAVITYMASTER GRB300-1A is crafted with a layered construction with a Carbon Core Guard structure leveraging the special properties of a carbon material also used in aircraft fuselages. Tested and proven G-SHOCK shock resistance and 200m water resistance (wr 20 bar) ensure the flight readiness of this aviation watch. The Super Illuminator LED light ensures excellent readability no matter the lighting condition, and Bluetooth® connectivity allows recording of flight log data such as location latitude and longitude, date, and time. That flight log data can then be displayed on a map on your smartphone using the Casio Watches app.
