Your IWC watch shows you the time in hours, minutes and
seconds, together with the date and the day. You can use the
integrated chronograph to measure any period of time up to
12 hours in seconds, minutes and hours. Stop times can be
added together. The mechanical movement with automatic
winding has 25 jewels (synthetic rubies) and a power reserve
of approximately 44 hours when fully wound. Your Pilot's Watch
Chronograph is water-resistant 6 bar and protected by a sapphire
glass of hardness grade 9 on Mohs' scale. The glass is retained
securely in the case at low pressure, for example when a drop in
air pressure occurs at extreme altitudes. Your watch has a double
case. The soft-iron inner case provides protection against mag-
netic fields. To ensure that this extraordinary watch continues to
perform faultlessly in the future, it is essential to observe a few
important operating instructions.
