Your IWC watch shows you the time in hours, minutes and sec-
onds, 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 a power re-
serve of approximately 68 hours when fully wound. Your Da Vinci
Perpetual Calendar Chronograph 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 gold
winds the watch in both directions of rotation via IWC's double-
pawl winding. 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 con tinues to perform fault-
lessly in the future, it is essential to observe a few important op-
erating instructions.
