Your IWC watch shows you the time in hours, minutes and sec-
onds, together with the date and the day. You can use the inte-
grated chronograph to measure any period of time up to 12 hours
in seconds, minutes and hours. Stop times can be added to gether.
The mechanical movement with automatic winding has 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. To ensure that this
extraordinary watch continues to perform faultlessly in the future,
it is essential to observe a few important operating instructions.
