Product Details

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.
