What really concerns me is the pitiful state of the movement.
What has caused the rhodium plating to be worn off in the way it has been? What has caused those parallel scratches across the line of the slot on the train bridge screw? What has happened to all of the debris caused by these two actions?
Re-plated case or not (I'm guessing, not) the state of the movement is just inconsistent with the state of everything else. To me, it looks like someone has bought an old movement that was knocking around loose in a drawer for a few years and stuck it into a NOS case/dial/hands from eBay.
Condition wise, the only things that seem to go together are the movement and the generic crown.
