Perpetual Calendar

The design of the perpetual calendar was a feat of watchmaking genius that finally paved the way for IWC’s entry into the world of Haute Horlogerie. A mechanical masterpiece, it takes into account all the complexities of the leap years; in other words, it recognizes all the years that can be divided, without remainder, by four (e.g. 2012), as well as the centuries that can be divided, likewise without remainder, by 400 (e.g. 2400). These leap years all have a 29th day in February. Years at the turn of the century that leave a remainder when divided by 400 – the next ones are 2100, 2200 and 2300 – are not leap years. In cases like these, calendars with an analogue display will need to be advanced by one day on 1 March by a watchmaker. Calendars with a digital display can be adjusted by the owner. The perpetual calendar’s century slide with an analogue display turns each new century into a major event. The current century slide bears the numbers 20, 21 and 22 and will thus come to the end of its service life on 31 December 2299; but even now, IWC supplies the century slide bearing the figures 22, 23 and 24 for the years 2200 to 2499.

A Tobacco Brown Dial For “Saint-Ex”

The Big Pilot’s Watch Perpetual Calendar Edition “Antoine de Saint Exupéry” and the Pilot’s Watch Double Chronograph Edition “Antoine de Saint Exupéry” both feature the same tobacco brown dials and brown calfskin straps with creamy white ornamental seams. In this way, they pay tribute to the extraordinary life’s work of this great humanist. Part of the proceeds from sales will go to the Antoine de Saint-Exupéry Youth Foundation. The perpetual calendar displays not only the cycles of the moon but also the seconds, minutes, hours, date, day, month and year in four digits. Until 2100, the differing lengths of the months and even the leap days in the Gregorian calendar are all factored in without the need for a correction. Powered by two barrels, the IWC-manufactured 52610 calibre has a 7-day power reserve and supports nine functions and displays. The rotor is made of solid 18-carat red gold. To the right, an engraving stating ONE OUT OF 750 indicates the special edition. The Double Chronograph in an edition of 1,000 features a split-seconds hand that permits the precise recording of two different times within a given minute. With its soft-iron inner case for protection against magnetic fields and sapphire glass secured against sudden falls in pressure, the watch has all the credentials of a watch designed for flying.

reference 5038

The perpetual calendar shows not only the lunar cycles but also the seconds, minutes, hours, date, day, month and year in four digits. All the displays are automatically advanced and take into account the differing lengths of the months and all the leap days in the Gregorian calendar until 2100 without the need for a single correction.
