The technical refinements of the
Portuguese Perpetual Calendar
Your IWC watch shows you the time in hours, minutes and seconds, the
moon phase, the day, the date, the month and the year in four digits as well
as the remaining power reserve. The mechanical movement with automatic
winding has 62 jewels (synthetic rubies) and a power reserve of 7 days
(168 hours) when fully wound. Your Portuguese Perpetual Calendar is pro-
tected by a convex sapphire glass of hardness grade 9 on Mohs' scale. Your
watch is water-resistant 3 bar. The engraved rotor with its 18-carat gold
medallion winds the watch in both directions of rotation via the Pellaton wind-
ing mechanism. In addition to the uniqueness of its functions, it is the display's
legibility and the ease with which it can be used that distinguishes this watch
from all other complicated timepieces. To ensure that this extraordinary watch
continues to perform faultlessly in the future, it is essential to observe a few
important operating instructions.
