Your IWC watch shows you the time in hours, minutes and
seconds, together with the date. The dive time is read off on
the internal rotating bezel, which for safety reasons can only be
turned anticlockwise. Your watch is water­resistant 30 bar and
protected by a sapphire glass of hardness grade 9 on Mohs' scale.
The mech anical movement with automatic winding has a power
reserve of approximately 60 hours when fully wound. To ensure
that this extra ordinary watch continues to perform faultlessly in
the future, it is essential to observe a few important operating
instructions.
