The evolution of the A-17. The new generation American pilot watch.
On December 31, 1948 Colonel J.C. Harvell, Chief of the USAF Equipment Laboratory Engineering Division, sent out a letter to the Waltham Watch Company and other watch brands asking for their comments on Specification n° 21277. This specification would later be known as MIL-W-6433.
At the end of 1948 the A-17 specification called for a Watch; Hack, Wrist, Luminescent Dial, 1300–2400 Auxiliary Markings, Type A-17. Further details of the specification were radium lume to be provided on the 1–12 hour markers, five minute markers, hour and minute hands, the tip of the sweep second hand and on the auxiliary 13–24 markings to facilitate the reading on 24 hour military time.
A tender issued to the Elgin National Watch Company, the Hamilton Watch Company, the Bulova Watch Company, the Gruen Watch Company and, surprisingly, the Longines-Wittnauer Watch Company. In the end the United States Air Force chose to exclusively use the Waltham Watch Company for their new Type A-17 Pilot’s watch.
A legend was born on March 23, 1951 when Mil Spec MIL-W-6433 was approved for the Waltham Type A-17.

F-86 Sabre pilots watch
The A-17 had the initial vocation to equip long range bomber crews based in Europe. Then it became the F-86 Sabre pilots watch during the Korean war. It also equipped the crews of the Boeing B-47 Stratojet and the F-104 Starfighter.
Reviews
The A-17 so far has proved accurate to one second per day on my wrist, measured against the Official US NIST time. I will look forward to other interesting Watch Angel time pieces.
