Welcome to February 29th! If you have a watch like the IWC Big Pilot's Watch Perpetual Calendar Top Gun, you'll perhaps have kept an eye on it at the start of this day, when the mechanical miracle of a perpetual calendar clicks to this date once every four years.
The IWC Big Pilot's Watch Perpetual Calendar Top Gun is one of the most complex pilot's watches ever built. Features 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 a reminder that IWC pioneered the use of these materials for watches.
