I'd say Bulova 23, very likely a swap at some point in the watch's history, but at least it is all '23'.
I strongly recommend (as always) getting the watch fully serviced by a qualified watchmaker. Dirty or dried out watches can and do damage themselves by running, and you cannot oil a dirty watch. It must be completely disassembled and done properly. The crown or the case tube is incorrect, and should be replaced with the correct one. It is too easy to snag a protruding crown, and having the stem ripped out can cause some serious damage.
