All I can say for sure is I recently bought a bracelet for my Sub. No questions, no handing my old one in, just a straight purchase with the offer to have them fit it if I wanted (I didnt). That was an AD. RSC was same price but would only sell it if I took the watch head in to have it fitted. Same price at both.
I have heard some newer models are designed to stop bracelet swaps, but I don't know which ones.
