Rolex 6263

[Watchcentric]

Hi,

I'm interested in buying a Daytona 6263 but it seems that there are quite some variations and I also have the impression that some of the For Sale 6263's I find on the web are not genuine.

Is there somewhere a good overview of the many variations in the parts (dials, bezels, pushers,...) and which of these parts belong together (for instance a Sigma dial and a MK5 bezel are probably not correct on the same watch?).

On the web this information seems very hard to find.
Maybe there are some good books ? which ones?

Or alternatively : are there thrustworthy and knowledgeable vintage dealers you can recommend? I live in Europe and don't mind traveling to other countries within Europe. For this kind of high-priced watches it's worthwhile traveling;)

Many thanks in advance!
