So I bought a lot with this Gruen in it and it doesn't work with a new battery.
Does anyone happen to know where I get a new one?
I found this one here: Gruen Precision 508 CA Electric Movement with Dial for Parts or Repair 7 Jewels | eBay
but the seller doesn't want to test it. :<
Anyways, it looks complete to me, but I have n o idea.
I also got this old Wittnauer. Does anyone know what kind of movement is in there?
