IWC Schaffhausen Pilot’s Watch Perpetual Calendar Chronograph “Le Petit Prince” (Ref. IW392202)

Presented at the Salon International de la Haute Horlogerie (SIHH) in Geneva in January 2019, the Pilot’s Watch Perpetual Calendar Chronograph (Ref. IW392202), is characterised by a distinctive midnight blue dial dedicated to Antoine de Saint Exupéry’s “Le Petit Prince”.

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. This watch features an 18 carat red gold case with blue dial, 18 carat gold hands and 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 IWC manufactured 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”.
