Your IWC watch shows you the time in hours, minutes and seconds, together with
the date. You can use the integrated chronograph to measure any period of time in
seconds, minutes and hours. Stop times can be added together. The mechanical
movement with automatic winding has a power reserve of approximately 68 hours
when fully wound. The engraved rotor winds the watch in both directions of rotation
via the IWC double-pawl winding system. Your Ingenieur Chronograph 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.
