Ceratanium® was developed by IWC and combines the advantages of titanium and ceramic in a single material. Based on a titanium alloy, the patented material is as light and rigid as titanium itself but at the same time as hard, wear-free and scratch-resistant as ceramic. Other compelling features are its skin-friendliness, high corrosion-resistance and striking matte black colour. All the case components, including the push-buttons and pin buckle, are made of Ceratanium®, which means the entire watch has a striking “jet black” design code. The Double Chronograph features an integrated split-seconds function that enables the watch to time two separate actions simultaneously. Its power is supplied by the 79420-calibre movement with automatic winding and a 44-hour power reserve. The watch has a black dial and hands. It is worn on a black rubber strap with a textile inlay.
