In 1983 Kurt Klaus invented the legendary IWC Perpetual Calendar including its full four-digit-year-indication. Until today it is a perfectly working mechanism that continues to power various IWC-models.
Kurt Klaus, IWC Ambassador and Master Watchmaker, today is a legend. At the time being Kurt Klaus was a visionary and pioneer when he invented his famous perpetual calendar that was used over many years first in the old and wonderful Da Vinci in combination with a chronograph and then made its way through the other IWC collections. The Kurt Klaus’ perpetual calendar mechanism is one of the most sold worldwide or even the most sold. I think no other watch manufacturer ever sold so many perpetual calendars as IWC in fact did.
Let us now welcome Kurt Klaus with a thunderous virtual applause. Kurt Klaus will give you some insights of his construction and then IWC-master-watchmaker Christian Bresser will tell you in which models IWC today is still using the Kurt Klaus mechanism.
