IWC Schaffhausen PORTUGIESER PERPETUAL CALENDAR Instrucciones De Manejo página 20

The technical refinements of the
Portuguese Perpetual Calendar
Your IWC watch shows you the time in hours, minutes and seconds, the moon
phase in both hemispheres, the remaining time in days until the next full moon,
the day, date, 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 protected by a convex sap-
phire 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 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 in-
structions.
