The IWC Big Pilot’s Watch Perpetual Calendar Tourbillon Le Petit Prince Ref. IW504901 combines two sophisticated high watchmaking complications in a distinctive blue ceramic design, limited to just 100 pieces. Its 46.5 mm ceramic case measures 16.1 mm in height and is paired with a blue dial and blue rubber strap. The watch features a screwed-in crown, 10 Bar water resistance, and a convex sapphire crystal with antireflective coating on both sides, secured against displacement caused by a drop in air pressure. Its perpetual calendar displays the date, day, month, leap year, and perpetual moon phase, while the flying minute tourbillon adds an exceptional level of mechanical complexity. The synthetic sapphire crystal case back provides a view of the movement.

At the heart of the watch is the IWC-manufactured Calibre 51950, an automatic self-winding movement operating at 19,800 Vph (2.75 Hz) with an impressive 168-hour, or seven-day, power reserve. Comprising 447 components and 54 jewels, the movement features Pellaton automatic winding, a hacking tourbillon mechanism, and refined Côtes de Genève and Perlage decoration. The combination of the perpetual calendar and flying minute tourbillon showcases IWC’s expertise in advanced mechanical watchmaking, while its blue ceramic construction gives the timepiece a distinctive contemporary character. Limited to 100 pieces, the Ref. IW504901 is an exclusive expression of the Big Pilot’s Watch and is eligible for up to 8 years of warranty through My IWC Care.
