Hello, This is a recent purchase I made primarily for the charm. The watch was listed as not working and the back of the case has been polished to the point that you can barely make out the Bulova under a loupe. The inside of the case has only swirls and service marks so I am unable to know for sure if it is solid or gold filled. The movement is stamped L5. The charm is lovely and is stamped 10K and Dieges & Custer. The watch is really pretty in person and started right up so I will be keeping it after all.
I believe this is an Academy Award "KK".
Edited: Adding a photo of this watch spruced up with a new pristine dial and NOS band like the original. Keeping the one that came with it as well.
