So I'm updating the movement record to show both 17 jewel examples as currently listed in root record, and to include 7 jewel examples as per photo posted below by Admin (and Mac's comments).
Do you guys think the 17 jewel entry could be a typo? I searched for both 7 and 17 jewel examples in the database, and found no occurances using both "10AB" and "10 AB" search terms. I know the 7 jewel movement exists :)
I have a Bulova 10AB date 1934. It is seven jewels like the one pictured above.
