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.
