PILOT'S WATCH MARK XVIII
THE TECHNICAL REFINEMENTS
OF THE PILOT’S WATCH MARK XVIII
Your IWC watch shows you the time in hours, minutes and
seconds together with the date. The mechanical movement with
automatic winding has a power reserve of approximately 42 hours
when fully wound. Your Pilot’s Watch Mark XVIII is 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
is water-resistant 6 bar. The soft-iron inner case provides pro-
tection against magnetic fields. To ensure that this extraordinary
watch continues to perform faultlessly in the future, it is essential
to observe a few important operating instructions.
