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 water-resistant 6 bar. The engraved rotor of 18-carat
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.
