A limited edition of 250, the Pilot's Watch Timezoner Spitfire Edition" The Longest Flight" combines the patented Timezoner mechanism with an in-house automatic movement. IWC developed the watch for the two pilots embarking on the "Silver Spitfire – The Longest Flight" endeavour to fly one of these iconic British fighter planes round the world. The watch is set to a different time zone by a simple rotation of the bezel. The hour hand, the 24-hour display (on a disc at 12 o'Clock) and the date all automatically adjust at the same time. The new IWC-manufactured Calibre IWC 82760 has a Pellaton winding system with ceramic components, for 60 hours of power reserve.
