The Pilot’s Watch Chronograph Edition “Antoine de Saint Exupéry” with date and day display precisely handles single and aggregate stop times of up to 12 hours. The self-winding system generates a power reserve of 44 hours, which is self-sufficient enough for long-haul flights. The numerals and hands on the clearly structured dial feature luminous coatings to ensure good legibility, even at night-time.
In 9 o’clock, you’ve got the sub-dial that suggests daily, and now at 3 o’clock you have the sub-dials that reveal the date and power reserve. At 6 o’clock, there is a month indicator and moon phase display, and to the left of it about 8 o’clock you’ve the year index. Ultimately, there’s the flying tourbillon that makes a single turning every second at 12 o’clock. The motion inside is the self-winding Iwc Watches Hong Kong Replica grade 51950, which is based on the Caliber 51900 found in IWC’s additional tourbillon watches like the Portugieser Tourbillon Mystère Rétrograde but with the ingenious 82-part endless calendar module developed by Kurt Klaus. This movement also contains IWC’s Pellaton winding system and contains a generous power book of 168 hours, or seven days. It’s observable through a sapphire display caseback and features a unique commemorative 18k gold rotor.The additional tourbillon see that IWC has specially prepared for its 150th anniversary is the Portugieser Constant-Force Tourbillon Edition “150 Years.” This comes in a slightly larger 46mm wide Portugieser style case and is only accessible platinum. Water resistance is a mere 30m, and the watch comes paired with a black alligator strap by Santoni.The Portugieser Constant-Force Tourbillon Edition “150 Years” includes a white lacquered dial with large black Arabic numerals printed in the signature ribbon of IWC’s Portugieser watches. Like the sooner Portugieser Perpetual Calendar Tourbillon Edition “150 decades,” this view also offers heat-treated blue hour and minute hands. This is an upgraded version of previous Constant-Force Tourbillon watches — Portugieser and other models — coupled with the “perpetual moon phase display. At 1 o’clock there is a moon phase display that only has to be corrected by means of a day following 577.5 decades. Beneath the moon phase display at roughly 4:30 is a power reserve indicator. Ultimately, we’ve got the highlight of this watch, the massive tourbillon featuring a constant-force mechanism that delivers power in even impulses into the escapement. In theory, this should enhance the chronometric performance of the movement.
This watch features the characteristic tobacco brown dial and is fitted with a brown calfskin strap by Santoni with decorative white stitching. This design is inspired by the typical overalls worn by pilots in Saint-Exupéry’s era. This model also features an engraving of a Lightning P-38 on the case back. It was in this particular model of aircraft that Saint-Exupéry took off on a reconnaissance flight from which he never returned.
This model features IWC’s tried-and-tested technology for pilot’s watches. The soft-iron inner case effectively protects the movement against the influence of magnetic fields, and the sapphire glass is specially designed to be protected against sudden drops in pressure in the cockpit.
