Bulova 1950 Academy Award

I've had this one for awhile, I wanted to get it entered, so here it is, a 1950 or thereabouts Academy Award, White Gold Filled case with caseback also GF. Excuse the expansion bracelet. As received, it came with a cylinder crystal, which I don't think is correct. The movement is stamped '49' and it runs quite well after its full overhaul. The curtain dial is in ok condition. The movt is a 7AK, 21 jewel with Breguet overcoil. I haven't done anything yet to the case, except for a quick polish of the bezel. It could use some more tlc, and the hands, on close inspection, are quite corroded. I do have NOS replacements for them, so will attend to that at some point.
