THE TECHNICAL REFINEMENTS OF THE
PILOT'S WATCH TIMEZONER SPITFIRE
Your IWC watch shows you the time in hours, minutes and seconds, together with the date. The
mechanical movement with automatic winding has a power reserve of approximately 60 hours when
fully wound. By turning the bezel with integrated city ring, you can conveniently set a different time
zone. The date change is also taken into account in this adjustment. The 24-hour display makes
differentiation between day and night possible. Your Pilot's Watch Timezoner Spitfire is protected by
a sapphire glass of hardness grade 9 on Mohs' scale. Your watch is water-resistant to 6 bar. To ensure
that this extra ordinary watch continues to perform faultlessly in the future, it is essential to observe
a few important operating instructions.
