The aviator timepiece was designed in collaboration with RAF pilots to include all of the features they need when in combat, including a stopwatch to record flight times and a thermometer to monitor cabin temperature. The watch also includes instant access to Zulu time - ensuring all pilots are using the same 24-hour clock, regardless of location.
The information is displayed using 'Smart Access' - an analogue movement that controls the hour, minute and second hands with individual motors, allowing the watch to quickly adjust to a different display.
RAF pilot Nathan Jones, who helped with the development of the watch, said: "There are so many aviator watches out there but it’s as though they were made having never seen or spoken to a pilot. This one has truly been made to make our job easier."
The GW-A1000RAF-1AER is jet grey (a neutral colour that matches the colour of both Royal Air Force flying suits) with hints of red, white and blue from the RAF logo. The carbon fibre strap and muted grey case were chosen on the basis that if a pilot lands in a hostile territory, he will not be given away by the shine or reflection of his watch.
G-Shock has described the model as its "toughest gravity watch to date", featuring 'Triple G Resist' technology that ensures the watch is resistant to shocks, vibration and centrifugal gravity.
As with all G-Shock watches, the time is kept accurate using atomic timekeeping. A device designed by Casio is built into the circuitry of the timepiece, and picks up radio signals from one of six atomic clocks around the world. It has a solar cell under the dial and a rechargeable battery to ensure long-lasting power.
RAF squadron leader John McFall said the timepiece included "a bespoke set of features inspired by the demanding and challenging environments worldwide in which today’s Royal Air Force personnel operate."
The G-Shock Premium Gravity Defier GW-A1000RAF-1AER is limited to 2,000 pieces. It will be available in June for around £500.
