This has been discussed on The Rolex Forum, in fairly great technical depth. It's been a while since I looked into it, but IIRC it should physically fit. However, I recall there was something unsatisfactory about it (the end link fit was ugly for some reason I can't remember). I'm fairly sure this is the case, since the "new bracelet onto old watch" isn't a popular modification, while "new clasp on old bracelet" is super popular.
