What should I do if the Cartier watch I bought in skp is defective?

You can report to the after-sales service and ask it to repair defects or replace parts.

But first, you should make sure that this is a defect in the product itself, not man-made. After the sale, you will conduct a comprehensive test to avoid making jokes.

Cartier watches bought at regular counters have problems within one year. You can find 10 thousand watches, the receipt you bought at that time, and his quality certificate. You can negotiate with the seller.
