LISBON – Unlocking Dark Mode, one component at a time. Material innovation and timeless design meet in the Portugieser Chronograph Ceratanium®, limited to 1,500 pieces. The first all-black version of the IWC Portugieser is made possible through a case, pushers, and crown made from Ceratanium®, an IWC-developed performance material that combines the properties of titanium and ceramic. The watch is powered by the IWC-manufactured 69355 calibre, a mechanical chronograph movement engineered with a focus on robustness, reliability, and longevity. A fully monochrome execution, with a black dial, hands, appliques, and textured black rubber strap, ensures the complete absence of color in this bold reinterpretation of an unmistakable silhouette.
