That matt greying effect is what happens when someone uninformed washes a dial and does not reapply any lacquer to the paint, the surface oxidises and I doubt it can be undone with a later application of lacquer. Hence the dial has no gloss, and a strange grey surface but seemingly correct fonts - the text survives a wash with this type of dial. The seller even admitted it was "cleaned" so he is not being dishonest.
It is possible someone washed a redial with exceptionally close fonts to an original but that would be more improbable than it just being a ruined original and would have likely removed the text. The bad image quality/greying is enough to confuse everyone but this is the most likely answer. I am not 100% certain though.
Ultimately the hands are all wrong/aftermarket, wrong crown, bad case and even if original someone ruined the dial so it is a pass.
