About the Pilot's Watches family
IWC's Pilot's Watches go back to the Special Pilot's Watch of 1936 and the Mark 11 of 1948, a navigation watch made for the Royal Air Force. Their typical features are a black dial with large numerals, a triangle at 12 and a soft-iron inner case on many models.
The modern family includes the Mark series up to the Mark XX, the Pilot's Watch Chronograph, the Spitfire and Top Gun lines and many special editions, with calibers such as the 32110 and 69385.
