SIHH 2019 - IWC Big Pilot's Watch Constant-Force Tourbillon Edition «LE PETIT PRINCE»
18-karat hard gold case, power reserve, tourbillon with built-in constant force mechanism, moon phase display, limited to 10 watches.
The Big Pilot's Constant-Force Tourbillon Edition "Le Petit Prince" (ref. IW590303) is IWC's first pilot's watch with a constant-force tourbillon. The watch with hard gold case is limited to 10 pieces. IWC produces here for the first time a watch with hard gold, a special new version of rose gold. The structure of the alloy is modified as part of a complex manufacturing process. Hard gold is therefore much harder and about five to ten times more resistant to wear than conventional red gold. The material is thus perfectly matched to the large case and the crown of a Big Pilot's Watch. The combination of the fascinating constant-power tourbillon with the poetic design elements of this "Le Petit Prince" edition makes this timepiece particularly extraordinary. The pink gold case forms a beautiful contrast to the blue dial and the moon phase complication.
