Not sure if this may be a Bulova 23 or a Beau Brummel, or "other". 4 diamonds on dial at 3, 6, 9 and 12. Original Spiedel gold band. Date code on case and movement is "L7". Case marked 14Kt gold fill. Keeps perfect time UNTIL I wear it, and then it will occasionally get "stuck"...I am guessing that having my arm at certain angles must affect something in the movement. Having a local watch maker/repairer look it over. No info on the history. Purchased last weekend at vintage jewelry store in Savannah, GA. Glare in first pic where face reads "Self-Winding".
In reply to Well, I found this ad someone by Geoff Baker
I think there was more than one Bulova 23 w/ diamond dial. Don't remember if we had ads for them, but I think they are in the price lists.
Here is a snippet from the Mens Diamond Dial section of the 1958 Fall price list, showing two variants w/ diamond dial.
I'm checking for more entries in other price lists, but there are some possibilities.
In reply to So Will, would it be the YW by Geoff Baker
The lugs do not match, they are of the "cat-ear" type, with a slight arching and a hollow point in the arch.
The diamond mounts do not match, each stone is set within a hexagonal white gold engraved mounting, the subject watch stones are set in round settings.
I believe the one in this 1957 ad to be the correct one, although both the artist's image of the lugs and the posted photos make it hard to be sure. Very close nonetheless.

Edit- here is an ad for the "YW" Bulova "23", same style, different colour in price list.
