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 approxi-
mately 68 hours when fully wound. The engraved rotor winds the
watch in both directions of rotation via IWC's double-pawl winding.
Your Ingenieur Chronograph Sport 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.
