Your IWC watch shows you the time in hours, minutes and seconds, as well as the
date, current dive depth and maximum depth achieved during your dive. The water
pressure (and thus dive depth) is measured by a pressure converter and transmitted
to the indicators, which show current dive depth and maximum dive depth down
to 50 metres. The depth gauge can be reset to zero using the adjustment crown to
correct fluctuations in atmospheric pressure. The dive time is read off on the internal
rotating bezel, which for safety reasons can only be turned anticlockwise. Your watch
is water­resistant 10 bar and protected by a sapphire glass of hardness grade 9 on
Mohs' scale. The mechanical movement with automatic winding has a power reserve
of approximately 42 hours when fully wound. To ensure that this extraordinary watch
continues to perform faultlessly in the future, it is essential to observe a few important
operating instructions.
