Your IWC watch shows you the time in hours, minutes and
seconds, together with the date and the day. You can use the
integrated chronograph to measure any period of time up to
12 hours in seconds, minutes and hours. Stop times can be
added together. The mechanical movement with automatic wind-
ing has a power reserve of approximately 44 hours when fully
wound. The Portofino Chronograph is water-resistant 3 bar and
protected by a sapphire glass of hardness grade 9 on Mohs'
scale. To ensure that this extraordinary watch continues to
perform faultlessly in the future, it is essential to observe a few
important operating instructions.
