I would stick with the original lock mechanism. The reason Cartier decided to modify the JUC lock is that clients complained about the difficulty of taking it off and on. I personally would rather know that my bracelet was very secure rather than have an extra diamond or two especially since the diamonds are so tiny. Please consider insuring your JUC if you decide to go with the newer version. I had a Love bracelet I purchased in 2012 to wear with one I already own from 2006. There had been a modification in the screw system in 2011 and my Love ultimately fell off and was lost. If you research this forum I wasn't the only person this happened to. While my insurance company covered the loss it is still upsetting.View attachment 3689474View attachment 3689475
I went in to exchange my bracelet and was this close to doing just that when I noticed that the new version has 2 diamonds more than the old. The nice SA also showed me another new model that is not defective like mine. It clicks and the hinge is tough as the old version. The result is that they need to get me a new one now.
The saga continues
