IWC Schaffhausen has developed a proprietary luminous ceramic technology called Ceralume®. Based on a highly engineered and patent-pending process, developed by IWC’s engineering division XPL, the technology enables IWC to produce fully luminous ceramic watch cases for the first time.

This is achieved by homogeneously mixing ceramic powders with high-grade Super-LumiNova® pigments, a luminous material that acts like a battery for storing light energy. In dark chamber tests, a fully luminous concept watch manufactured using the Ceralume® technology has emitted a bright blueish light for more than 24 hours.
