I bought this Bulova 23 Jewel about a year ago. It was rather dirty but it ran well and with a little cleaning up it shined like new. I love this watch's flair with it's brilliant gold lettering and the sunburst dial. It runs very accurately and has gone from a watch that I wore every day, to one that's somewhat reserved for special occasions. The case is 10K RGP and is dated 1955 (L5). It is the 23 jewel BPAC movement. But the movement is dated 1958 (L8). Is it normal for cases and movements to be a few years apart like this? From what I've found in the model database, this watch looks to be the 23 "C" model.

Agree with 23 'C', 1955 based on case. As common as these watches were, it seems unlikely that there would be a three year difference between case and movement. Perhaps, the movement was changed early on during warranty service.

I wasn't sure whether I should have dated the watch based on case or movement, so I went with the movement date. A warranty movement change sounds like it makes sense to me as to the difference in dates.
I agree that it's most like a replacement movement. I would date it to 1955 as well.
