Black dial with 2 diamonds at 12 position and a jewel on the crown like a ladies watch, but sized like a mens. This was a "what the heck is that" purchase that I assumed had a replaced crown. Much to my surprise, I found a single other example in the database that is identical. That one was uploaded in 2015.
That is a simplistic design but elegant, love it!

I looked high and low and cannot seem to find a model number. Unknown for me.
Same here, unable to match it with a number...Unknown
1979 Bulova Unknown
Found an ad for this model but unfortunately no name.

Looks like it's called "Alluring" :-)
Found these references in the 1977-79 linebook (BAWD0213) that closely match the watch design. Not 100% sure they are describing the same watch, but sounds the same.
Mode: 02683-7Y
....and the Model 02972-Y which seems a better match again, noting the similar model numbers and price..

It has to be one of these. I am leaning towards 02972-Y
