I don't wear one of these A-11 very often. These are the only bezel A-11 produced. There are documents from air station Pensacola from Pan Am (the airline company) mentioning these. About 1200 were produced. The movements have special US Army AC markings on them for the Army Air Corps. Looks like grandma's watch, but they most likely flew in the early 1940s over Europe. This one came with a US Naval Academy band. If you know the history of Weems watches, then you will recognize that P.V.H. Weems developed this watch as a cheaper alternative to the full sized 47mm Weems for the US Army that was mainly training at North Island San Diego for the Celestial Navigation he developed that made it possible to navigate at aircraft speeds. This is a bomber navigator's watch.
