This one blew me away when I found it. Such a cool early 20's Bulova in an American Standard 19K case, decorated with a butterfly at each corner and maybe a bouquet in the middle of each lug filigree hood. The sides and back of the case are classic Bulova design we see repeated throughout the 1920's on other ladies models.
Looks like the 17 J, 6PP.I. movement predates the date stamps.
Second number in these early ones at times indicate the year. I'm good with 1923.
A really unique piece.
