Your IWC watch shows you the time in hours, minutes and seconds with hands, the
date and the month in a large digital display as well as the leap year. You can use the
integrated flyback chronograph to measure any period of time up to 12 hours in sec-
onds, minutes and hours. Stop times can be added together. The dive time is read off
on the internal rotating bezel, which for safety reasons can only be turned anticlock-
wise. The mechanical movement with automatic winding has a power reserve of ap-
proximately 68 hours when fully wound. The rotor winds the watch in both directions
of rotation via the IWC double-pawl winding system. Your watch is water-resistant
10 bar and protected by a sapphire glass of hardness grade 9 on Mohs' scale. In add-
ition to the uniqueness of its functions, it is the display's legibility and the ease with
which it can be used that distinguishes this watch from other complicated timepieces.
To ensure that this extraordinary watch continues to perform faultlessly in the future,
it is essential to observe a few important operating instructions.
