⌚ IWC Pilot's Watches: value and history

Official IWC Schaffhausen playlist «2026: #IWCpilot» on YouTube.

Let There Be Light. IWC engineers once again push the boundaries of advanced material engineering. By day, the Big Pilot's Watch Perpetual Calendar Ceralume® reveals subtle gradations of white; by night, it transforms, emitting an intense blue glow for hours. This unmatched effect is enabled by Ceralume®, a proprietary luminescent ceramic technology developed by IWC’s engineering division, XPL, in collaboration with RC Tritec. For the first time, the dial and rubber strap are also infused with Super-LumiNova® pigments, delivering an unprecedented fully luminous watch. Ref. IW505801
