I can understand how, say, a 1944 movement can pop up in a 1945 case: One factory is making the movements to be used as needed in a number of models, another is making new designs of cases to fit standard movements. You might even get a couple of years off. But the watch I'm lookintg at is a 1954 Craftsman carrying not the expected 1954 8AE 21j movement but a (very similar-looking) 1944 8AC movement.
The first solution that springs to mind is that the original movement was damaged, so some jeweler replaced it with a working one from 10 years earlier. But the case and movement are in equally lovely shape. Is it reasonable to think that the factory came across a few unused 10-year-old movements and put them in the appropriate new cases? Or that they were out of the 8AE movements one day and used some old 8AC movements they had on the shelf, knowing that they would fit perfectly in the watch? Have experienced Bulova folks seen this sort of thing occasionally and decided that it wasn't a Frankenwatch after all?
Many thanks. The collective wisdom (and good humor) on this site has provided me a delightful education as I wade into Bulova collecting.
