Bulova 1966 Priscilla "B"
I just found this in the bottom of a box of stuff in my work space, and have no idea when or where I got it. Don't recall ever seeing it before..........
The only ad I could find for pendant watches in the Db dates to 1969 and shows Priscilla "G" and "H". I suspect that this is likely a Priscilla, but that's a guess based on the fact there are 6 letters preceding "G" and ad is 3 years newer than watch date.
Face marked "Swiss", inside of case marked "W Germany".
