The Annual Calendar (Ref. 5035) is IWC’s first annual calendar and closes the gap between the perpetual calendar and the simple date display. The month, date and day are shown in three separate, semicircular windows at “12 o’clock” while the date switching mechanism is able to take the differing lengths of the individual months into account.

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.
