The technical refinements of the
Ingenieur Double Chronograph Titanium
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 us-
ing 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 Ingenieur
Double Chronograph Titanium is protected by a sapphire glass of hardness
grade 9 on Mohs' scale. Your watch is water-resistant 12 bar. To ensure that
this extraordinary watch continues to perform faultlessly in the future, it is
essential to observe a few important operating instructions.
