The Pilot’s Watch UTC Spitfire Edition “MJ271” is limited to 271 pieces. MJ271 was the original call sign of the "Silver Spitfire" during its time of service. In the project "Silver Spitfire – The Longest Flight", this airplane will be the first Spitfire ever to circumnavigate the globe in 2019. The bronze case, olive green dial and brown leather strap combine to lend the timepiece a character of its own. Over time, the bronze develops an individual patina. The UTC mechanism makes it very easy to set a second time zone. Turning the crown one way or another in its intermediate position causes the hour hand to jump forward or backward in one-hour steps. If the International Date Line is crossed in the process, the date display likewise changes automatically. The time at home can be read off in the IWC-typical arc-shaped UTC display in the upper half of the dial. The newly developed, IWC-manufactured 82710 calibre features Pellaton winding with components made of non-wearing ceramic and has a 60-hour power reserve.
