Original U.S. WWII 1944 Army Air Force B-17 Navigator Type A-8 Jitterbug Stopwatch by Elgin with Box

Item Description

Original Item: Only One Available. The Type A-8 was a navigation stopwatch designed for timing ground speed meters for determining the velocity of aircraft relative to the ground. One revolution of the Type A-8 hand was equivalent to ten seconds. The dial was white on early Wittnauer Type A-8 watches and black on Elgin watches produced from 1940 onward. Elgin, Waltham, the Federal Television Corp. and Aristo Import Co. manufactured Type A-8 stopwatches under military specification MIL-W-6510. Under MIL-W-6510, continuous running movements were required to have not less than 15 jewels and the non-continuous movements were required to have not less than 9 jewels.

This is a wonderful condition fully functional 100% authentic 1942 dated aircraft navigator's Watch, Navigation (Ground Speed) Stopwatch, Type A-8, made by ELGIN for the U.S. Army Air Corps. Type A-8 stopwatches were used in any WWII aircraft with a navigator, such as heavy (B-17, B-24, B-29) and medium bombers (B-25, B-26) and large transports (C-46, C-47, C-54).

The outer ring of the dial counts up to 10 seconds and the inner dial located at the standard 12:00 position count up to 10 minutes of the 10-second revolutions. The A-8 was known as the jitterbug because of the loud and fast ticking of the balance at 144,000 beats per hour. Yep, just try to hear that over the cacophony of multiple radial engines.

The back is nicely but faintly marked:
