IWC Portugieser Perpetual Calendar 42 | IW344202

The IWC Portugieser Perpetual Calendar is the pinnacle of the Portugieser family. The calendar complication, a first in history showing the 4 year digit display and entirely activated by the crown by developed by legendary watch maker Kurt Klaus. Instantly recognisable in its forward thinking over sized and hugely legible case, the IWC Portugieser Perpetual Calendar is a firm favourite amongst collectors and enthusiasts alike.

Offering a fully perpetual calendar, with day, date, month, year and moonphase functions – the actual calendar is accurate for over a century without any adjustment while the moonphase is accurate for half a millenia. An amazing feat of engineering all done before CAD systems and computers. The perpetual calendar is a vital complication for any proper marque and IWC holds its own.

IWC’s perpetual calendar, developed by Kurt Klaus in the 1980s, automatically recognizes the different lengths of the months and the leap years and can easily be adjusted via a single crown. Now, for the first time, the complication is 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 o'clock", "6 o'clock" 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 18-carat 5N gold case, a silver-plated dial, gold-plated hands, and 18-carat gold appliqués. This timeless, elegant Portugieser is fitted with a brown alligator leather strap from Santoni.
