I have recently purchased a 5513 from an esteemed member of this forum. I then took the watch to my local Rolex dealer for authentication, insurance appraisal, and a quick once over with verification of the seals and water resistance. All checked out until the watchmaker pulled the movement appart for authentication. A few issues have arisen and I would like a second opinion as they have deemed authentication 'inconclusive' and that the watch needs to be sent to Rolex for final authentication.
Image 1 - The concern is the lack of engine turning in the circled area. He feels this whole area should have engine turning in it.
Image 2 - The concern is the 'P'. He expects to see a 'R'.
Image 3 - The concern is the highlighted case screw. This seems improper.
My question is fairly simple. Do I need to be concerned and how concerned should I be? Are these normal variations in Rolex parts? Do I have some nominally value-affecting aftermarket parts? Or do I have a major issue?
