Bulova 1958 Bulova 23

I could only upload a face and back picture, as I already have the watch packaged to send to Mike Cousineau on Monday for repair, and I didn't take the back off to get a picture of the movement. Case material is 14Kt gold. I had watch repaired at least 20 years ago. Worked ok for a couple years, now gains time again. Crystal has been replaced at least once. Obviously, band is not original. Has been in family since around 1960 when my father purchased from his hard-up-for-money best friend for $25. I can get the movement details when I receive watch back from Mike, or I can ask him to relay them to me when he send the watch back. I went through all of the 1958 ads and even the 1957 and 1959 ads. I  couldn't find a picture of a similar watch with the same dial (no numbers). I assume this is another derivation of the "23"? Thanks. Great website, BTW!
