IWC – BIG PILOT's Watch Constant-Force Tourbillon Edition "Le Petit Prince"

IWC Schaffhausen – BIG PILOT's Watch Constant-Force Tourbillon Edition "Le Petit Prince" Special Editions

LE PETIT PRINCE: 

MASTERPIECES OF HAUTE HORLOGERIE

Since 2005, IWC has been in collaboration with the family of French aviator and author, Antoine de Saint-Exupéry. This partnership has already seen a variety of special editions launched within the Pilot’s Watches collection. While some pay tribute to the life and accomplishments of the great humanist himself, others are dedicated to his most famous literary work "The Little Prince" (Le Petit Prince). These timepieces, characterised by their distinctive midnight blue dials, have been a highly regarded addition to the Pilot’s Watch collections since 2013. And at the upcoming SIHH, the manufacturer will now be adding some exclusive models to this line.

One such model is the Big Pilot’s Watch Constant-Force Tourbillon Edition "Le Petit Prince" (ref. IW590303). It is the first pilot's watch from IWC to feature a constant- force tourbillon. It is available with a hard gold case and is limited to 10 watches.

This is the first time IWC has produced a watch with hard gold, a special new version of red gold. The microstructure of the alloy is modified in a sophisticated manufacturing process. Hard gold is therefore significantly harder and around 5 to 10 times more wear-resistant than conventional red gold. As a result, the material is perfectly suited to the large case and the crown of a Big Pilot’s Watch.

The patented constant-force tourbillon is the IWC engineers' answer to a centuries-old challenge in the field of watchmaking: As the tension in the spring of a mechanical wristwatch slackens over time, less force is transferred to the escapement via the dial train, which in turn decreases the amplitude of the balance. This has a negative impact on the precision of the watch. The patented constant-force mechanism separates the escapement from the direct flow of force from the dial train and with every second re-tensions a balance spring, which serves as a temporary store of energy and transfers absolutely even force pulses to the escape wheel. Integrated into a tourbillon, which also eliminates the influence of gravity on the oscillating system, the result is extraordinary precision.

The IWC-manufactured calibre 94805 combines a constant-force tourbillon with a perpetual moon phase display, which takes 577.5 years to require adjustment by one day. The "Petit Prince" stands on the moon. Two barrels store enough power for 96 hours. A display notifies the wearer of the remaining power reserve.

PORSCHE DESIGN – 1919 Chronotimer Flyback Black & Leather

PORSCHE DESIGN – 1919 Chronotimer Flyback Black & Leather Titanium 42

Focusing on Maximum Functionality

Porsche Design expands its series of 1919 Collection timepieces with the introduction of the 1919 Chronotimer Flyback Black & Leather. Paying meticulous attention to detail, intelligent design meets maximum functionality, putting the Porsche philosophy directly on the wrist. Tested and certified by the official Swiss Chronometer Testing Institute (COSC), the innovative 1919 Chronotimer Flyback Black & Leather – in addition to its technical features – stands out and competes through use of its sophisticated silhouette and subtle design cues.

A Style-Defining Classic

Like the legendary sports car, the timepiece provokes with its minimalist design, un-compromising functionality, and outstanding performance. The Porsche 911 has been the benchmark for sports cars since 1963 – synonymous with racing, victory, emotion, and innovation. It was also the inspiration for the company founded by Professor Ferdinand Alexander Porsche. In 1972, Porsche Design introduced the Chronograph I, a classic that shaped the entire world of watches: the first matte black chronograph, mirroring the 911’s speedometer and tachometer.

The new 1919 Chronotimer Flyback Black & Leather is a continuation of this uncompromising de-sign with a clear focus on functionality: an all-black understated interpretation of the classic designed by F. A. Porsche. The sleek design of the generously proportioned dial focuses on the essentials, while the dark contrast guarantees excellent legibility.

Lightweight Engineering for the Wrist

The legendary sports car and the exclusive timepiece also share the same genesis in featherweight construction: this is optimized engineering for the wrist. Every 1919 Collection model – including the 1919 Chronotimer Flyback Black & Leather – is made entirely of titanium.

The chronograph’s strap is made of high-quality cowhide leather, just like the seats of a Porsche, utilizing the same attention to detail as in the sports cars.

Maximum Performance

The innovative watch, powered by the Porsche Design Werk 01.200 caliber, – equipped with a state-of-the-art flyback complication – can quickly measure successive intervals, such as lap times on the racetrack. The 4-hertz automatic movement is the result of cutting-edge production methods combining in-house engineering and watchmaking expertise with vehicle manufacturing proficiency.

The movement’s exposed automatic bridge provides an unobstructed view of the flyback mechanism and the automatic gears, thereby systematically implementing Porsche’s approach to lightweight engineering. The energy-optimized Porsche Design rotor, visible through the sapphire crystal back, is PVD-coated and carries a tungsten weight. Thanks to its heft, the material helps provide the energy necessary for maximum winding power.

The 1919 Chronotimer Flyback Black & Leather will be available as of September 2019 for 5,950 Euros (RRP) at Porsche Design stores, specialty retailers, and online at www.porsche-design.com.
