I saw this watch go on ebay a few weeks ago. I did not purchase it, nor do I know the owner of this watch.
I asked the seller permission to post it for database purposes and was given permission to use the information and the pictures.
Really cool late 1920's Lady Bulova with enamel enlay. I've not seen this one before, nor have I seen an ad for it.
Unknown from me, but really neat anyway.
Here's what the seller described the watch as in the listing:
