Ceralume® marks a new chapter in ceramic innovation.
With the introduction of the Big Pilot’s Watch Perpetual Calendar Ceralume® (Ref. IW505801), IWC pushes the boundaries of advanced material engineering. By day, the watch 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, theleading innovator in Super-LumiNova® technology. Following its debut in a concept watch in 2024, this breakthrough material now enters the IWC Pilot’s collection.
For the first time, the luminescence extends to the white dial and rubber strap, both infused with Super-LumiNova® pigments, delivering an unprecedented fully luminous watch. Visible through the sapphire glass case back, the medallion integrated into the rotor is made of SuperLumiNova®, adding further luminous detail to the back of the watch.
