Your IWC watch shows you the time in hours, minutes and sec-
onds, together with the date. The mechanical movement, which
is timed in five positions, with automatic winding, a temperature-
compensating balance spring made of Nivarox of the highest
®*
quality and an unbreakable Nivaflex mainspring, has a power re-
®*
serve of approximately 42 hours when fully wound. Your Portofino
Automatic is protected by a sapphire glass of hardness grade 9 on
Mohs' scale. Your watch is water-resistant 3 bar. The rotor of the
automatic winding system is mounted by means of a ball bearing
with ceramic balls. To ensure that this extraordinary watch con-
tinues to perform faultlessly in the future, it is essential to observe
a few important operating instructions.
