IWC Portugieser Annual Calendar

The newly developed annual calendar shows the month, date and day in three separate, semicircular windows. The date advance system takes the different lengths of the months into account. Only February and the leap years need to be corrected manually using the crown. The new IWC-manufactured 52850 calibre has two barrels that together generate a seven-day power reserve.
