Your IWC watch shows you the time in hours, minutes and sec-
onds, 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 stop-
ping 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 Titanium is protected by a sapphire glass of hardness 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.
