There are plenty of posts that advocate not sending the watch back to China for repairs. There were also repairers listed in the trusted dealer sections. Yes, its a bit late for that, and am sorry you might have to suffer financial loss on this. Perhaps you could have asked these questions before sending a $500 item back to a known communist country.

But surely you cannot expect the TD to be responsible for customs issues and provide you a good price. It will be an unsustainable business model. Again, sorry for your travails. But this is a replica business without ebay/amazon returns policies.
