As an Army Air Corp aviator during WWII, my father, a Bombardier on B-26 Marauders was "issued" a watch as part of his equipment. In fact, he was issued two as the first one he had was lost on a bombing mission where his canopy took some flak hits. He was issued a second watch but subsequently found his other watch...so he had two. This "issued" watch was not returned at the end of the war...or the end of his military service. Most likely it was just one of those "items" that was deemed expendable by the military as once issued to the service member, they were able to keep it. I can't speak for all aviators, but obviously, as a Bombardier, and if any of the WWII military movies are accurate...during their mission pre-briefings, a "time hack" is done for mission accuracy. It wasn't a real fancy watch with additional bells and whistles...just a standard rotary dial with 24 hour markings on a black face. After dad passed, I found his receipt for one of the issued watches. That went with the watch to my brother and I have the second watch...one that dad wore faithfully and cared for until he passed away. It is now in his shadow box set at the time he died. I would like to see your watch if you would like to send to my e-mail address. Hope this helps answer your question.
