The Spitfire, designed by Reginald J. Mitchell, is one of the most sophisticated developments in the history of aviation. The iconic shape of the legendary British fighter aircraft is the result of a perfectly functional design; its elliptical wings not only make the Spitfire extraordinarily agile and easy to manoeuvre, they also give it its unique silhouette. The characteristic instrument design of IWC’s Pilot’s Watches was likewise the result of engineering to the specific requirements of military aviation (please find more detailed information in separate article). “Just like the Spitfire, our watch collection of the same name also perfectly combines form and function. The design is inspired by the puristic instrument design of the iconic Mark 11 navigation watch. This watch demonstrates our engineering expertise, as we have integrated high-quality IWC-manufactured calibers into all Spitfire models,” explains Christoph Grainger-Herr, CEO of IWC Schaffhausen.
The Big Pilot’s Watch Perpetual Calendar Spitfire (Ref. IW503601) features a perpetual calendar and is limited to 250 watches. The 52615 IWC-manufactured calibre has a power reserve of seven days. The heavy-duty components of the Pellaton winding are made from wear-resistant ceramic. The perpetual calendar identifies different month lengths and leap years automatically and will work until 2100 without needing any correction. Since all displays are perfectly synchronized, the watch can be easily adjusted via the crown. The double moon display shows the moon in the correct position in the northern and southern hemisphere and takes 577.5 years to require adjustment by one day. The see-through sapphire glass back allows the user to view the highly embellished IWC-manufactured calibre.
