What should European tourists do if they buy fake watches in a watch shop near the Eiffel Tower in Paris?

Try to choose a bigger store for overseas shopping.

Large formal shopping stores will provide vouchers such as shopping invoices; However, many small shops do not provide these related bills, and it is difficult to defend rights without evidence. Even if there is a bill, it is necessary to prove that the watch is fake. It is necessary to have an appraisal document issued by a professional appraisal institution to ask the store to make compensation and other related follow-up operations. Because it is transnational, it is likely to be a very long process.
