The Portuguese Automatic is one of IWC's most famous and successful models since 2004 when it was first launched, at that time the latest expression of a series with 65 years' history. This year's edition has a warm red gold case with a dark brown dial, and two black subdials that add contrast and match the black crocodile strap. Arabic applied numerals, chapter ring, feuille hands, everything adds to the overall image of harmony. Perhaps one of the most attractive aspects can be seen through the transparent caseback: the fact that the 51011 calibre takes up almost the complete diameter of the case, corresponding to the very narrow bezel. The Pellaton automatic winding system has a 7-day (168 hours) power reserve, indicated by the right-hand subdial. The movement is finished to the habitually high standards, with circular graining, nickel plating and Geneva stripes decoration. The watch is water-resistant to 3 bar.
