Notes: As I recall, this is the first Bulova I owned. I gave it to my sister some years ago, but she never wore it because she prefers larger watches. Since she had recently acquired a higher-end tu-tone Tissot PRX, I traded her for a blue dial mid 70s PR516 with integrated bracelet. She loves it, and I have my little Bulova back. I wear it, as it is actually fairly long on the wrist. If men will wear a tiny Cartier tank, why not.
I did an exhaustive search of the MyBulova database to ID this. At first I thought it was an Ambassador, as it is identical except for minor details to the dial. Then I found the Craftsman “B”, which appears to be the same in every way. I also found many 1947-48 His Excellency “GG” to “II” models, that have the same case in the photos. However, these indentifications were originally assigned fairly early on, like around 2013. I followed a couple of ad links, and I believe actual His Excellency “GG” models have a similar, but scooped out lug. It does look similar from an overhead view, but the difference can be seen in oblique. I think most, or all, of these to be Ambassadors. Correct me if I am wrong.
Welp... with the solid 14K I think you have the Bulova "Tuxedo".

Hi Plainsmen,
That surprised me, I thought that it could only be a "Tuxedo" if it had the solid gold bracelet?
In reply to Hi Plainsmen, That… by gmmy775
That statement certainly rings a bell from a previous discussion, in which we determined the lack of a bracelet meant rulled out the Tuxedo ID.
So we have a watch we ID'd as a Craftsmen back in 2015, which shows an advert detailing both the Tuxedo and Craftsman. Bulova Craftsman "A" for me.

The ad cannot be any clearer. Without a bracelet it is a 1947 Bulova Craftsman "A"
Ah... good catch boys.
