On January 14, 2019, Schaffhausen, Switzerland-IWC Schaffhausen added IWC Pilot Watches to its Pilot’s Watches series with LePetitPrince and Anthony Saint Exupery ‘(Antoinede Saint Exupéry) special edition watch, will be unveiled at the Geneva International Horological Fair (SIHH). The new large pilot constant-power tourbillon watch’ Little Prince ‘special edition is IWC’s first pilot series with constant-power tourbillon Watches. Swiss watchmaker IWC Schaffhausen has also applied hard gold for the first time to the case, creating a red gold model that has a significantly higher hardness and more wear resistance. In addition, for the first time, IWC IWC perpetual calendar and The chronograph function is integrated into the Pilot’s Watch series, and the new Pilot’s Watch Perpetual Calendar Chronograph “Little Prince” special edition is launched.
These unique special edition watches are distinguished by the midnight blue dial. This is also the IWC watch created for French writer and pilot Anthony Saint Exupéry’s most important and important literary work ‘The Little Prince’. of.
IWC IWC Large Pilot Constant Power Tourbillon Watch The Little Prince Special Edition (model IW590302 / IW590303) is the brand’s first pilot series watch with a constant power tourbillon. The case is available in hard gold and platinum. The two models are limited to 10 pieces each.
Platinum case, blue dial, rhodium-plated hands, brown calfskin strap (model IW590302)
18K hard gold case, blue dial, gold-plated hands, brown calfskin strap (model IW590303)
This is the first time IWC has produced a watch in hard gold—a new special edition red gold watch. The microstructure of the alloy is changed by a complex manufacturing process. Therefore, the hardness of hard gold is greatly improved, and its wear resistance is about 5 to 10 times higher than that of traditional red gold materials. The resulting material is ideal for the large case and crown of large pilots.
The patented constant-power tourbillon is a solution researched by IWC designers for a century-old challenge in the watchmaking industry: because the clockwork in mechanical watches will gradually loose and lose over time. Correspondingly, the force transmitted to the escapement mechanism via the stitching gear train is also gradually reduced, which in turn leads to a reduction in the balance frequency. This has a negative impact on the accuracy of the watch. The patented constant power mechanical device separates the escapement mechanism from the direct energy flow of the power from the needle train, and re-tightens the balance springs every second, thereby achieving temporary storage of energy. And it can transmit absolutely smooth energy pulses to the escapement wheel, and then integrate it into the tourbillon, thereby completely eliminating the influence of gravity on the oscillation system. The result is extraordinary precision.
In addition to the constant-power tourbillon, the self-made movement of IWC 94805 also integrates the perpetual calendar moon phase display function. It only needs to be adjusted one day every 577.5 years. The ‘Little Prince’ stands on the moon. Two barrels provide ample power storage for 96 hours. The power reserve display lets the wearer know at any time how much power the watch has left.
IWC Pilots’ Perpetual Calendar Chronograph Watch ‘Little Prince’ Special Edition (model IW392202), IWC for the first time integrates the calendar and chronograph functions into the Pilot’s Watch. Limited to 250 pieces.
18K red gold case, blue dial, 18K gold hands, brown calfskin strap
The perpetual calendar mechanism developed by KurtKlaus in the 1980s can automatically detect different days in different months and leap years. The device has only about 80 parts, but it can run until 2100 without adjustment. The date, week, month, moon phase and year display are perfectly synchronized, and if the watch is not worn for a long time, it can be easily adjusted through the crown. IWC-manufactured calibre 89630 is also equipped with a chronograph function. Therefore, the moon phase display is integrated into the chronograph at 12 o’clock.
