I went to Cartier today to send out my new four diamond love bracelet for engraving. My SA told me about a new “screw enhancement” they just came out with, not glue, it’s a piece of hardware I believe. She suggested to get that done as well while it’s out for engraving, she said she can really feel the difference of how secure they screws feel with the enhancement. I complied and sent it in but I’m a little nervous and can’t find any mention of this new enhancement. Has anyone had this done?
