Looks like a Bulova 23 Le Petite
Is it the camera angle and crystal which is making this dial look like it doesn't fit the bezel?
Should this be ID'ed as a Bulova 23?
The movement data base shows the 5AR movement made from 1963 till 1965.
...and I sure can't see a datecode on the movement photo...
So 1951 (L0) case and unknown movement date, but age can be ranged by production of 5AR.
Movement swap, and maybe dial swap w/ movement swap...as I still think it looks like the dial doesn't quite fit the bezel.
Non Conforming, I'd say.
