IWC Portugieser Tourbillon Rétrograde Chronograph
IW394007
The Portugieser Tourbillon Rétrograde Chronograph pairs the cool weight of platinum with the depth of a rich blue dial. Its flying minute tourbillon at six o’clock anchors a carefully balanced arrangement of the retrograde date and the combined chronograph hours-and-minutes display, bringing substantial mechanical information into clear focus. Powered by the automatic calibre 89900 with flyback timing and a 68-hour reserve, this 43.5 mm creation expresses complexity with quiet assurance.
