Your IWC watch shows you the time in hours, minutes and seconds,
the month, the date and the day, 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 Big Pilot's Watch Annual Calendar is protected
by a convex sapphire glass of hardness grade 9 on Mohs'
scale. Your watch is waterresistant 6 bar. The engraved rotor
of 18carat 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
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.
