Your IWC watch shows you the time in hours, minutes and seconds, together with
the date and the day. You can use the integrated double chronograph to measure any
period of time up to 12 hours in seconds, minutes and hours using the split­seconds
hand (rattrapante) to record intermediate times or a second finish time. Stop times can
be added together. The watch is water­resistant 6 bar and protected by a sapphire
glass of hardness grade 9 on Mohs' scale. The glass is retained securely in the case
at low pressure, for example when a drop in air pressure occurs at extreme altitudes.
The mechanical movement with automatic winding has a power reserve of approxi­
mately 44 hours when fully wound. The soft­iron inner case provides protection against
magnetic fields. To ensure that this extraordinary watch continues to perform faultlessly
in the future, it is essential to observe a few important operating instructions.
