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.
