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 a power reserve of approxi­
mately 7 days (168 hours) when fully wound. The rotor winds the
watch in both directions of rotation via the Pellaton winding system.
Your Big Pilot's Watch is water­resistant 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.
