The IWC Big Pilot’s Watch 43 Tourbillon “Le Petit Prince” Ref. IW329502 combines the imposing character of the Big Pilot’s Watch with exceptional haute horlogerie craftsmanship. Its 43 mm case is crafted from 18-carat Armor Gold®, an innovative and particularly hard gold alloy, and is paired with a deep blue dial featuring an elegant sunray finish. A brown calfskin strap complements the precious-metal case, while the convex sapphire glass features antireflective coating on both sides and is secured against displacement caused by drops in air pressure. The watch also incorporates a flying minute tourbillon with a hacking mechanism, allowing the tourbillon to be stopped for precise time setting.

At its heart, the IW329502 is powered by IWC-manufactured Calibre 82905, an automatic, self-winding movement featuring the Pellaton automatic winding system and an 80-hour power reserve. Operating at 28,800 vibrations per hour (4 Hz), the movement comprises 197 components and 25 jewels and can be admired through the synthetic sapphire crystal case back. The 43 mm case measures 14.5 mm in height, features a screwed-in crown and offers 10 bar of water resistance. With its 18-carat Armor Gold® construction, flying minute tourbillon and distinctive “Le Petit Prince” inspiration, this is a highly sophisticated collector’s timepiece that brings together IWC’s aviation heritage and advanced mechanical watchmaking.
