The new Portugieser Annual Calendar brings together two firsts for IWC and three masterstrokes of haute horlogerie in a single case: the newly developed annual calendar closes the gap between the perpetual calendar and the simple date display. The new IWC-manufactured 52850 calibre has two barrels that keep the new function supplied with ample energy and still has enough left for a 7-day power reserve.
