Your IWC watch shows you the time in hours, minutes and sec-
onds, the moon phase in both hemispheres, 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
a power reserve of approximately 7 days (168 hours) when fully
wound. Your Portugieser Perpetual Calendar is protected by an
arched-edge sapphire glass of hardness grade 9 on Mohs' scale.
Your watch is water-resistant 3 bar. The engraved rotor made of
18-carat red gold winds the watch in both directions of rotation
via the Pellaton winding system. 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 compli-
cated timepieces. To ensure that this extraordinary watch continues
to perform faultlessly in the future, it is essential to observe a few
important operating instructions.
