Your IWC watch shows you the time in hours, minutes and sec-
onds together with the date. The mechanical movement with
automatic winding has 21 jewels (synthetic rubies) and a power
reserve of approximately 42 hours when fully wound. Your Pilot's
Watch Mark XVI for Father and Son is protected by a sapphire
glass of hardness grade 9 on Mohs' scale. The glass is retained
securely in the case at low pressure, for example when a drop in
air pressure occurs at extreme altitudes. Your watch is shock-
proof, antimagnetic and water-resistant 6 bar. To ensure that this
extraordinary watch continues to perform faultlessly in the future,
it is essential to observe a few important operating instructions.
