I ran the serial # and it came back being dated to 1946, other than that and the 10L movement, I am clueless. I bought the watch because I enjoy how it looks, but I’d love to understand more about it!
Looks like a 14-karat gold case. You have bought a watch with a movement that is very much in need of a thorough professional recondition. It looks to be all there, with no serious damage evident, but it sure looks tired. This watch is neither shock resistant nor water resistant. Most people today, consider a watch to be a disposable item, to be used up and turfed when they quit. This one has potential, but should see gentle, respectful wear as an occasional wearer. If it was mine, one of the first things I would do would be to dump that entirely inappropriate high dome crystal, and replace it with a low profile crystal. A low dome crystal would leave lots of room for the hands to clear. The case should be cleaned only, and light polish by hand with a polishing cloth, but not buffed.
