When does a Rolex stop being a Rolex?

[Qoopy]

So, I do not yet own a Rolex, however, I think I may be in the market for one, or, I thought I was…here’s my dilemma:

I cannot afford a new Rolex, so I have been shopping the used market through the internet from many trusted web sites that have been mentioned here. It seems the watches that I can afford have had their bracelets replaced, and many have had a crystal conversion to sapphire done as well. Are these watches even considered desirable anymore? They “look” beautiful, but are they still worth the money seeing they have had so much work done to them?

Maybe it’s just that I cannot buy an all original Rolex, so I’m pushing the envelope of affordability? Thanks to all who offer their educated opinion.
