Bulova 1932 Nurse

Here is a head scratcher, got lucky and won this off of the bay yesterday...not in hand yet, but most of the info is in the pictures except the crystal size, which is missing. Most of these old snap-on cushion cases that have the alignment pin are found on early 1920's Elgins, and Walthams, this is the first that I have seen on a Bulova. Case serial would indicate 1922 or 1932, and the movement date stamp would indicate 1931 as far as we know, and maybe the movement serial number will help shed some light to back this up. This looks more like a early 20's watch than a early 30's.  Discuss away...
