600$ can get you a watch like this that has NOT been redialed and in better condition, overall. It's better that you decided to return it. Just take your time and do some research, read about various watch models and different time periods and you'll find a much better deal.
Over exposed pictures from the seller hide a multitude of sins but I believe that it is the same watch. I know that you could replicate the position of join in the crystal armour but it is unlikely that you would get it spot-on and replicate the extent to which the "SWISS MADE" was obscured.
Exactly. It's the same watch without doubt. A classic example of a seller using photographic editing tools to make something look better than it actually is.
