Your IWC watch shows you the time in hours, minutes and
seconds, as well as the date together with the power reserve on
the side facing the movement. The mechanical movement has
a power reserve of approximately 8 days (192 hours) when fully
wound. Your Big Pilot's Watch Big Date is protected by a convex
sapphire glass of hardness grade 9 on Mohs' scale, which is
retained securely in the case at low pressure, for example when
a drop in air pressure occurs at extreme altitudes. Your watch is
water­resistant 6 bar. The soft­iron inner case provides protec-
tion 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.
