Your IWC watch shows you the time in hours, minutes and sec-
onds, together with the date. The watch is water-resistant 12 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. The
soft-iron inner case provides protection against magnetic fields.
To ensure that this extraordinary watch continues to perform fault-
lessly in the future, it is essential to observe a few important op-
erating instructions.
