Pilot functions inspired this Casio G-Shock Premium Sky Cockpit model, this watch features a digital compass with 20 second history, allowing you to maintain a course or bearing easily. This model also benefits from a neon illuminator backlight, that lights the hands and markers out in low light at the touch of a button. The movement is quartz, and also features a thermometer, world time with 48 world cities, 24 hour chronograph with split function, five alarms, date with full auto calendar, and countdown timer. The case is water resistant to 20 atm, and is a stainless steel core, with resin protective pieces, giving the watch incredible shock resistance. The watch fastens on a link bracelet in a mixture of black ion plated steel and polycarbonate for ultimate lightness and strength.
