THE STORY

The Portugieser Annual Calendar is available with a stainless-steel case and silver-plated dial. Located at “12 o’clock” on the dial, the annual calendar shows the month, date and day in three separate, semicircular windows. Its advance mechanism automatically takes the length of individual months into account and requires manual correction via the crown once a year at the end of February. The rare combination of an annual calendar and 7-day calibre makes this complication from IWC even more fascinating for watch connoisseurs. The arched-edge sapphire glass makes the case look slimmer and underscores the watch’s classic elegance. The curved strap horns ensure greater comfort even on a slimmer wrist. On the reverse side, the see-through sapphire-glass back provides an unimpeded view of the exquisite new IWC-manufactured 52850 calibre.

Calibre Family 52000

Calibre Family 52000

The twin barrels are the trademark feature of the 52000-calibre family. They supply the watches with sufficient energy for a 7-day power reserve and drive energy-sapping complications like the annual calendar and perpetual calendar.

Annual calendar

The annual calendar is an attractive complication that shows the month, date and day in three separate windows on the dial. This complication automatically takes into account the differing lengths of individual months. It took 5 years to design.
