1927 Claire? Although a bit more engraving and detailed face than other Claires of this year.
Bulova American Standard case.
Dear Leltykeltner, your watch is a typical Art Deco watch with this beautiful engraving. Unfortunately it is unknown.
Love the engraved dial on this one! I also could not find a match.
Unknown for now
Love the look of this one with that great engraved dial. I'm also unable to find a match - sorry :o(
1927 Unknown
Please note that I changed the first digit of the case serial from 8 to 6. Correct case serial number is 6658389. So far I found three examples of this model with a case serial number starting with 665. All had 1927 movements…….
I see why the Clare gets a mention, case shape and bezel opening is the same. Price point would inidicate a 15J movement.
So it;s just the engraving f the case and dial.

Another case and bezel opening match is for the Baroness, although this advert is dated 1930.

That Baroness ad is a mistake. Only one jeweller used it while the original Baroness was still sold and advertised by many jewellers.

Upon review, that certainly seems the case. Same outer case shape, but with a different inner bezel opening.
Great looking watch, alas, 1927 Bulova Unknown
