and hard to imagine how you initially felt when you realised what you had in your hands and also how you could do anything differently other than to return the watch to the auction house for a refund and expect the right thing to then happen and at the very least the watch to be deposited with the Police (or lawyers) whilst the matter was investigated, but never for it to be sent back to the consignor. In retrospect I guess you would inform the Police what had happened and what action you had taken. I had a similar experience in a different line but only contacted the Police as the auction house (and consignor via them) refused to accept the item was stolen despite all of the proof I presented. In the end it turned out the Police (and manufacturer) were very much on the case and following many avenues of buying and selling very carefully until they were ready to make their move ensuring they had the ringleaders and not just the fences.
