Portugieser Perpetual Calendar Tourbillon Edition “150 Years”

Premiere in the anniversary year : the Portugieser Perpetual Calendar Tourbillon Edition “150 Years” unites the perpetual calendar from Kurt Klaus with a tourbillon on the dial.

With the Portugieser Perpetual Calendar Tourbillon Edition “150 Years”, IWC combines the legendary perpetual calendar from Kurt Klaus with a tourbillon on the dial for the first time. This masterpiece of watchmaking is available in a limited edition of 50 watches. It has an 18-carat 5N gold case, a white dial with a lacquered finish, and blued hands. The watch is powered by the IWC-manufactured 51950 calibre, an extension of the 51900 calibre with the addition of a perpetual calendar. To make the tourbillon visible at “12 o’clock”, the designers opened up the calendar advance ring and integrated the moon phase in the month display at “6 o’clock”. This tourbillon complication is made up of 82 individual components and weighs just 0.635 grams. With its solid gold rotor, the automatic Pellaton winding system generates a power reserve of 7 days.
