I received this watch this morning and have spent the last few hours cleaning it up. The movement is a 21jewel 7AA and is marked A9 but the case is marked L0 ,so it would be classed as a 1950 model. The case was very tarnished and the dial was nearly brown, it must have belonged to a heavy smoker. It has come up great. I believe it is an Academy Award. the movement is running fine . It requires a new crystal as it is scratched and has a small hole in one side. and maybe a new strap to finish it off.
If any member has a crystal that would fit this watch, I would be more than happy to purchase it from them.
