One of Steve McQueen's favorite watches was a Hanhart 417 chronograph watch.
The watch worn by Steve McQueen has a stainless steel case with a black dial and two subdials. It was worn on a large leather strap.
Hanhart is a German manufacturer that specialized in producing chronographs for the German Air Force. The company still exists today and even produces a modern version of the 417 and a 1954 version.
