IWC Schaffhausen - Portugieser

Portugieser Perpetual Calendar 42 Boutique Edition

Gold, 42.4 mm. Made in Switzerland Model IW344205
Editor's notes

With the Portugieser Perpetual Calendar 42, IWC integrated this popular complication into an in-house movement from the 82000-calibre family. IWC’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 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 sub-dials 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 special edition with a diameter of 42 millimetres in a nautical design is available exclusively at IWC Boutiques and online at It has an 18-carat 5N gold case, a blue dial, gold-plated hands, and 18-carat gold appliqués. The timeless, elegant Portugieser is fitted with a blue alligator leather strap.
