The story behind it

Pan Am's crews were flying across time zones as intercontinental air travel took off, and Rolex worked with the airline on what its pilots needed. The extra 24-hour hand and two-colour 24-hour bezel let them read a second time zone, and Rolex says the watch became the official watch of several airlines.
