​About the 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 caliber has two barrels that together generate a seven-day power reserve.
