The Big Pilot’s Perpetual Calendar Ceralume is a technical showcase of IWC’s engineering, featuring a fully luminous ceramic case. Developed by the XPL experimental division, the Ceralume process mixes ceramic powder with high-grade Super-LumiNova to create a material that emits a bright blue glow for several hours. This concept watch combines IWC’s iconic perpetual calendar complication with a matching luminous dial and strap for a monochromatic, high-visibility aesthetic. The movement requires no manual adjustment until the year 2100. This watch presents in brand new condition, with no signs of wear. This timepiece comes with its original box, booklets, and warranty card. The IWC International warranty will be valid until 2034. We ship fully insured overnight via FedEx or UPS.
