THE TECHNICAL REFINEMENTS OF THE
BIG PILOT'S WATCH PERPETUAL CALENDAR
Your IWC watch shows you the time in hours, minutes and seconds, the moon phase in both
hemispheres, the day of the week, 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 shockproof
and water-resistant to 6 bar. The engraved rotor with its 18-carat gold medallion 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 extra ordinary watch continues to perform faultlessly
in the future, it is essential to observe a few important operating instructions.
