The IWC Big Pilot’s Watch Perpetual Calendar Ceralume IW505801 is a revolutionary masterpiece that pairs IWC’s legendary horological engineering with the world’s first fully luminescent ceramic case. This limited-edition timepiece is a striking monochrome instrument by day and an otherworldly, blue-glowing marvel by night, pushing the boundaries of material science and high-end watchmaking. Pioneering Ceralume® Case: Features a patent-pending luminous ceramic material developed by IWC’s XPL division that emits a bright blueish glow for over 24 hours. Legendary Perpetual Calendar: Mechanically programmed to accurately display the date, day, month, and four-digit year without manual adjustment until the year 2100. Double Moon® Display: Includes IWC's signature moon phase for both Northern and Southern Hemispheres, so precise it deviates by only one day after 577.5 years. High-End Calibre 52616: Driven by an in-house automatic movement featuring a 7-day (168-hour) power reserve and a virtually wear-free Pellaton winding system. Fully Luminous Design: The glow extends beyond the case to the white luminescent dial, hands, subdial components, and even the integrated white rubber strap. Limited Edition: Exclusively limited to just 250 pieces worldwide. Expertly Crafted Details: Visible through a sapphire glass case back, the movement features circular graining, blued screws, and a luminescent "Probus Scafusia" rotor medallion.
