How to solve the problem that the second-hand watch warranty card has been used?

If the warranty card of the second-hand watch you bought has been used, you need to take the following steps:

1. First, you need to contact the second-hand seller and ask about the guarantee of the card. Find out whether the warranty card is still valid and whether the warranty card covers the warranty service of your watch.

2. If the warranty card has expired or is no longer valid, you need to contact the watch manufacturer or its authorized service provider to find out whether your watch can enjoy the warranty service. If you can, you need to provide relevant documents, such as proof of purchase or transfer agreement, to prove that your watch was indeed purchased within the validity period of the warranty card.

3. If your watch is really purchased within the warranty period, but there is still no warranty service, you can contact the watch manufacturer or its authorized service provider for a solution. They may provide you with some alternative warranty services, such as maintenance services or parts replacement.

If the above steps fail to solve the problem, you may need to stop using the watch and apply for a new warranty card. Before you apply for a new insurance card, you need to ensure that your watch meets the relevant standards and regulations and is legally purchased.

In short, if the warranty card of the second-hand watch you bought has been used, you need to know the warranty card carefully and contact the watch manufacturer or its authorized service provider to find a solution.
