First one is a recase. Seller is hiding that fact. Second could be original. Very early period when dials were custom design option available. Dizmonkey does not seem to touch what he has. Crown on second is not 13zn. PS: I am newbie, so others should know more.
I contacted seller of first one. Said only that serial number and case don't match. Problem is also you don't even know if the dial matches the movement without the serial number. Could be completely Franken
The dial on Antimagnetic is likely good. The movement is likely good. Case we can't tell what it is. The price is cheap if all belong together. I would price it as a collection of parts to reduce the risk to myself. If a factory delivered original, asking price is low from a profession seller.
