The watch is a fake. I don't know how they can sell fakes when they are approved by experts. You can see in the messages exchanged with the seller how he himself has already acknowledged that is fake.

Der Verkäufer hat sofort annuliert weil die Uhr würde nicht so hoch gestiegen wie er sich gewünscht hatte und wollte mir erzählen das die Uhr würde irgendwo anders verkauft. 

After I won the lot and paid for it, the seller cancelled the process and didn't send me the watch. Not a reliable seller, don't buy from him.

very good seller, watch in great condition
