The technical refinements of the
Pilot's Watch Double Chronograph Edition TOP GUN
Your IWC watch shows you the time in hours, minutes and seconds, together
with the date and the day. You can use the integrated double chronograph to
measure any period of time up to 12 hours in seconds, minutes and hours
using the split-seconds hand (rattrapante) to record intermediate times or a
second finish time. Stop times can be added together. The mechanical
movement with automatic winding has 29 jewels (synthetic rubies) and a
power reserve of approximately 44 hours when fully wound. Your Pilot's
Watch Double Chronograph Edition TOP GUN is water-resistant 6 bar and
protected by a sapphire glass of hardness grade 9 on Mohs' scale, which is
retained securely in the case at low pressure, for example when a drop in air
pressure occurs at extreme altitudes. Your watch has a double case. The
soft-iron inner case provides protection against magnetic fields. To ensure
that this extraordinary watch continues to perform faultlessly in the future, it
is essential to observe a few important operating instructions.
