Big Pilot's Watch Perpetual Calendar Top Gun

High technology meets Haute Horlogerie: the Big Pilot’s Watch Perpetual Calendar TOP GUN comes with a wealth of features that will send the adrenaline levels of watch lovers soaring. They include the IWC-manufactured 51614-calibre movement with high-performance Pellaton winding system that builds up a 7-day power reserve. This efficient movement drives multiple watchmaking complications. Apart from displays for the date, day and month, the perpetual calendar has a four-digit year display that takes into account all the leap years in the Gregorian calendar until the year 2100. All these displays can be easily adjusted with the crown and advance automatically. The moon phase display represents the position of the moon in the northern and southern hemispheres. The Big Pilot’s Watch Perpetual Calendar TOP GUN combines the classic instrument look with the sport-inspired design of the TOP GUN line. The ceramic case and titanium crown are further indications of IWC Schaffhausen’s innovative technology and a reminder that it discovered these materials for use in its products. This timepiece is one of the most complex pilot’s watches ever built.

Analogue date displays with hands have a long tradition in IWC watches featuring perpetual calendars. In the case of the Portuguese Perpetual Calendar, for instance, the date, day and month are to be found on three subdials and, thanks to the clear layout, are extremely easy to read. The classic moon phase display – whether a single moon, or a double one for the northern and southern hemispheres – is based on discs and is usually found at “12 o’clock”. The moon phase displays used in the Grande Complication and the Da Vinci Perpetual Calendar Edition Kurt Klaus are astonishingly accurate and deviate by just 0.002 percent, or one day, after 122 years. The Portuguese Perpetual Calendar is even more precise. Larger moon phase wheels with different numbers of teeth reduce the deviation so drastically that a future inheritor of the watch would theoretically need to take it to a watchmaker to have it adjusted by only one day in 577.5 years.
