Your IWC watch shows you the time in hours, minutes and
seconds with hands, the date and the month in a large digital
display as well as the leap year. You can use the integrated flyback
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 winding has a power
reserve of approximately 68 hours when fully wound. The rotor
winds the watch in both directions of rotation via the IWC double
pawl winding system. Your Ingenieur Perpetual Calendar Digital
DateMonth is protected by a convex sapphire glass of hardness
grade 9 on Mohs’ scale. Your watch is waterresistant 12 bar.
In addition to the uniqueness of its functions, it is the display’s
legibility and the ease with which it can be used that distinguishes
this watch from other complicated timepieces. To ensure that this
extraordinary watch continues to perform faultlessly in the future,
it is essential to observe a few important operating instructions.
