This classically elegant Portugieser is equipped with an annual calendar. This useful complication developed by IWC shows the month, date, and day in three semicircular windows at “12 o’clock”. The mechanically programmed annual calendar automatically recognizes the differing lengths of the months and requires only one correction per year, at the end of February. The watch is housed in a case made from stainless steel. The deep green dial and golden hands lend this timepiece a classy overall impression. The see-through sapphire-glass case back provides an unimpeded view of the IWC-manufactured 52850 caliber. With the help of two barrels, the efficient Pellaton automatic winding system builds up a power reserve of 7 days. A display at “3 o’clock” informs about how much energy remains available.
