The Portugieser chronograph ceratanium

The Portugieser Chronograph Ceratanium® is powered by the IWC-manufactured 69355 calibre, a mechanical chronograph movement engineered with a focus on robustness, reliability and longevity. The column-wheel control mechanism for the chronograph function provides clearly defined phases in the switching sequence and offers distinct tactile feedback when the buttons are pressed. The movement features an automatic doublepawl winding system, which reliably builds up a power reserve of 46 hours in the mainspring. Alongside the Ceratanium® case, crown, and pushers, the watch features a black dial with black appliques and hands, and a rubber strap in the same shade.
