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.
