The watch normally issued to U. Army Air Corp navigators to help them make ground speed calculations while airborne.
Navigators would use the stopwatch to calculate the timed distance between two known landmarks on the ground. This watch has a very fine original black dial with light patina and the original painted white hand. The timer's outer ring with Arabic numerals counts up to 10 seconds and the subdial covers up to 10 minutes of the 10-second revolution of the large hand.
The superclean 15-jewel mechanical movement winds and runs. I would recommend a proper service.
The push button stops and starts the center counter hand, and resets it and the 10-minute dial to zero. The nickel round case shows wear on the back indicating heavy use. The back engraving reads: AN A231.
It appears use has smoothed down the normal engraving. The watch comes with a new crystal. The case has been lightly polished.These watches earned the nickname "jitterbug" because of the loud, fast ticking of a small balance wheel operating at 144,000 BEATS PER HOUR. The fast speed helped ensure accuracy. My father was a WWII B-17 pilot so I have an interest in World War II militaria. I describe my items as accurately as is possible. All wristwatches will need servicing at regular intervals. If I know the service history, I will indicate it in the description.
