IWC Portugieser Mens Watch IW344202IWC’s perpetual calendar, developed by Kurt Klaus in the 1980s, automatically recognises the different lengths of the months and the leap years and can easily be adjusted via the single crown. Now, for the first time, this has been integrated into a movement from the 82000-calibre family. The Portugieser Perpetual Calendar 42 displays the date, month and weekday on three subdials at 3, 6 and 9 o'clock. It also features indications for the moon phase and the leap year. With the help of ceramic components, the IWC-manufactured 82650 calibre’s Pellaton winding system builds up a power reserve of 60 hours. This timepiece with a diameter of 42 millimetres has an 18k gold case, a silver-plated dial, and gold-plated hands and 18k gold appliqués. Presented on a brown alligator leather strap from Santoni, this timepiece is timeless and elegant.
