Hi, Bulova Friends --
I fell into this ladies wristwatch. The case is marked M8 for 1968, with SN N40568. I haven't attempted opening it to see the movement ... it's a tiny timepiece, and it's running.
What strikes me is (1) the lovely detailed bracelet, and (2) the odd open lugs. As for (2), I'm wondering whether there was ornamentation that was removed at some time, leaving the frame.
Anyway, it's more a girl's First Communion watch than a lady's watch. The bracelet would fit a child's wrist only. I wish I could find the same bracelet that hasn't been so reduced in size!
