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 29 jewels (synthetic rubies) and a
power reserve of approximately 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.
