IMHO it’s a great deal. Nothing wrong with buying preowned, especially it has all the paper work. Go for it!I have a small thin gold JUC bracelet and a regular WG with diamonds. I am thinking of getting a regular gold or rose gold JUC bracelet from the preloved market for everyday wear. I found one for about $6k with COA and receipt purchased in 2017. The seller has paper showing it was recently brought to the Cartier boutique for polishing done. Is this a good deal since it already has polishing done and original purchase date was 2017? I've heard polishing should not be done often. Thank you in advance for your insight!
