Based on that picture alone, nothing really looks off to me. Maybe the date wheel and red button have been replaced at some point (their respective colors look very fresh and homogeneous). But that might easily just be the picture, or luck. Bezel, mkII dial, hands all look OK and I don't think the case looks overpolished. At the right price, this could be a nice pick-up.
Just got the archive extract in the mail today for mine
