Detailed features & specifications
The Portugieser Annual Calendar is available with a stainless-steel case and blue 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
The highly efficient winding system is a refined version of the 50000-calibre family with a bidirectional Pellaton pawl-winding system. Two barrels provide an impressive 7 days’ power reserve. The winding pawls and the automatic wheel are made of black ceramic while the rotor bearing is made of white ceramic.
These extremely hard high-tech materials make the automatic winding system practically wear-free. The indexless balance with a frequency of 4 hertz (28,800 beats per hour) and the Breguet spring guarantee maximum precision. The design and finish of the movement was also considerably enhanced. The proportions of the rotor and the inset “Probus Scafusia” gold medallion are noticeably slimmer.
