My 1963 GMT 1675 with Silver Dial?

The notion that it is "authentic by default" if they accept it for service will always leave uncertainty, because we know of many examples of watches with questionable parts that have been serviced by Rolex. Personally, if I were a potential buyer, I would not accept the fact that it had been serviced by Rolex as equivalent to an authentication.

The difference here, however, is that this is the Rolex Heritage Department, which deals specifically with vintage and presumably has much more expertise. This isn't a random RSC that might have missed a fake bezel insert on a vintage Sub they serviced.

While perhaps not definitive proof of complete authenticity, the fact that they have accepted the watch for service is at a minimum a very good sign for Eric.
