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 approxi-
mately 7 days (168 hours) when fully wound. Your Portuguese Perpetual
Calendar is protected 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 winding 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 distin-
guishes 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.
