Pilot’s Watch Perpetual Calendar Chronograph

IWC INTRODUCES LE PETIT PRINCE AND ANTOINE DE SAINT EXUPÉRY SPECIAL EDITIONS

Schaffhausen, 14th January 2019 – at the Salon International de la Haute Horlogerie (SIHH) in Geneva,  IWC Schaffhausen will be presenting two “Le Petit Prince” models and an “Antoine de Saint Exupéry” special edition in the Pilot’s Watches collection. The Big Pilot’s Watch Constant-Force Tourbillon Edition "Le Petit Prince" is the first pilot's watch from IWC with a constant-force tourbillon. For the first time, the Swiss watch manufacturer has used hard gold for the watch case – a significantly harder and more wear-resistant version of red gold. With the Pilot’s Watch Perpetual Calendar Chronograph Edition “Le Petit Prince”, IWC has for the very first time combined a perpetual calendar with a chronograph function.

These timepieces, characterised by their distinctive midnight blue dials, are dedicated to Antoine de SaintExupéry’s “Le Petit Prince”. It is the most important literary work by the French writer and pilot.

In the Pilot’s Watch Perpetual Calendar Chronograph (Ref. IW392202), IWC has combined a perpetual calendar with a chronograph for the first time in a pilot's watch. 250 of these limited edition timepieces are available.
 -  18 carat red gold case, blue dial, 18 carat gold hands, brown calf leather strap
The perpetual calendar developed by Kurt Klaus in the 1980s automatically detects the different number of days in the month as well as leap years. The mechanism, which is built from just 80 or so parts, will work until 2100 without needing to be adjusted. The displays for date, day, month, moon phase and year are perfectly synchronised and can be easily adjusted via the crown if the watch is not worn for a prolonged period. The IWCmanufactured calibre 89630 also features a chronograph function. The moon phase display for the calendar is therefore integrated into the chronograph counter at "12 o'clock".
