Bulova 1937 Kenmore
This is what I believe to be a 1937 Kenmore based on the following previous ID.
It is rather small at 26mm x 32mm lug to lug. It is yellow gold plate or filled and has a cream dial with applied gold hour markers. The movement is an 10AE and has the arrow date code. It is missing the minute hand and is not currently running. On an original gold topped Kriesler bracelet. The back has been filed down or worn smooth so there is no case seriall number.
