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 a power reserve of
approximately 7 days (168 hours) when fully wound. Your Big Pilot’s Watch Perpetual
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.
