Your IWC watch shows you the time in hours, minutes and seconds, together with the
date and the power reserve. The mechanical movement with automatic winding has
42 jewels (synthetic rubies) and a power reserve of approximately 7 days (168 hours)
when fully wound. The engraved rotor winds the watch in both directions of rotation
via the Pellaton winding mechanism. Your Big Pilot's Watch for Father and Son is pro
tected by a convex sapphire glass of hardness grade 9 on Mohs' scale. Your watch is
shockproof, antimagnetic and waterresistant 6 bar. To ensure that this extraordinary
watch continues to perform faultlessly in the future, it is essential to observe a few
important operating instructions.
