Update: NOS to Used. After closer inspection under microscope we believe that these are not new old stock movements, but used ones. We can see some marks here and there, screw heads and plates, but they show no physical damage otherwise, if they do we would not post them. Of course we dont take them apart so we cannot be aware of all issues they might possibly have. This is the bad news the good one is that we can provide spare parts should you need them or you can send the movement back and we give you a refund no problem. Peace and love!
1 x EB 8420-73 movement without balance assembly and the parts from the dial side also missing. (calendar ring, canon pinion, hour and minute wheel, calendar plate with washers and screws)
These were made more than 40 years ago and were sitting in that protective box, they must be serviced before use.
