@iwcwatches: The first fully luminescent ceramic watch. Ceralume® is a high-tech ceramic compound, developed by IWC, that combines ceramic with Super-LumiNova®. The Big Pilot's Watch Perpetual Calendar Ceralume® absorbs and stores light, re-emitting it after dark as a vivid blue glow. To craft this groundbreaking new material, IWC engineers designed a dedicated ball-milling process. Ceramic powders and @swisssuperluminova pigments with different particle sizes are broken down into a homogenous powder, for a flawless end result. Ref. IW505801 #IWCwatches #IWCpilot
