Having done some research, I have come up with the following:
Bulova did not make a Beau Brummel with 17 jewels this late in the 1960's or early 70's. They were all 23 or 30 jewels, which tends to rule out the Beau Brummel as an option. Plus, the whale would look a bit out of place on a BB, so I'm less inclined to put it in that group.
Statistically, we have ads or info on 13 confirmed Golden Clipper models (A,B,C,D,E,F,H,J,K.L,M,O, and an unlettered 12610 variant), strongly hinting that there are at least a couple more missing models in the lineup.
This watch shares many characteristics with the 1970's GC line, right down to the gold plated movement, which was a signature feature of the line (see the 1970 "sword" ad for more info). All GC's had 17 jewels, auto, water resist, with face details consisting of "Bulova" and the whale with the "Automatic" (other than the unusual J model). This strongly suggests a connection to this line.
Most of the GC line share the 11ANAC movement (+ date and day/date variants 11ANACD and 11ANACB). This is not universal, however it is highly prevalent in the line. This movement is also seen in the Clipper and, to a lesser extent, Sea King and Date King lines, although not as firmly established.
I have put together a spreadsheet with some of this information that I am tracking, and will see if I can find additional models to support further analysis.
