I need some feedback on this latest purchase. Purchased over the phone from an estate sale. Looks like an early Bellmatic, confirmed 27 jewels, looks like a silver dial, said to be running and working properly, obviously not the original bracelet. Is this a rare/early version? I could not see the caseback. Got it for $83. I'm thinking I got a pretty good deal, any info you all can give me from the terrible picture would be greatly appreciated.
