Technical refinements
of the Aquatimer Chrono-Automatic
Your IWC watch shows you the time in hours, minutes
and seconds as well as the date and the day. With the
integral chronograph, you can measure any period up
to 12 hours in seconds, minutes and hours. The duration
of the dive is read off on the bezel housed inside the
case, which for safety reasons can only be adjusted
in an anti-clockwise direction via the reset button. The
mechanical movement with automatic winding has
25 jewels and a power reserve of at least 44 hours when
fully wound. This watch is shockproof, antimagnetic,
water-resistant 12 bar and protected by a scratch-
resistant sapphire glass of hardness grade 9. To ensure
that this extraordinary watch continues to perform its
tasks in the future, it is essential to observe a few
important operating instructions.
