sjunky13, my RG with the new screw system kept falling off too. Thank goodness I was home when it happened. The screws kept coming loose (within 24 hours) no matter how many times I tighten them. I took it to my local store and of cos they said they have never had any problems. Regardless, they took it in and send it to NYC for repairs. Anyhow, it came back after 2 weeks and no one could tell me what was fixed, wth. I had the SA screw on the bracelet for me in-store. The SA tried to pull it apart to test it and I had DH do the same. So far, it has been 4 days and the bracelet is still nice and tight. I purchased my bracelet last October so it is under warranty. They polished it for me as well so it is very nice and shiny right now. I hope that Cartier will take care of your problem. Good luck!
