Your IWC watch shows you the time in hours, minutes and
seconds, together with the date. A 24-hour hand shows you an
add itional time zone of your choice. As you pass through a time
zone, you can adjust the hour hand of your watch in steps without
stopp ing the mechanical movement (Time Zone Corrector = TZC).
The date change is also taken into account in this adjustment.
The mechanical movement with automatic winding has a
power reserve of approximately 42 hours when fully wound. Your
Ingenieur Dual Time is protected by a sapphire glass of hard-
ness grade 9 on Mohs' scale. Your watch is water-resistant 12 bar.
To ensure that this extraordinary watch continues to perform
faultlessly in the future, it is essential to observe a few important
operating instructions.
