I recognise that watch. It was posted on the paneristi forum late last year and the guy who now owns it explained that it is a frankenwatch. According to him it was assembled from an assortment of OEM parts, including a genuine 201A dial, but with a standard ETA/Unitas 6497 movement. It has a caseback from a C or D series 001. The regular Paneristi congratulated him on this 'unique' piece, rather than call it out as a fake. There's obviously a fine line here.... franken = OK........rep = hanging offence.
