The other big problem is that Panerai doesn´t give a sht. I used to send Panerai/Richemont emails with links to obvious reps. They didn´t reply and they didn´t pull the listings. Some of them never get pulled because eBay´s response time is variable, but if the manufacturer intercedes and they are in the VERO program (they are, or used to be anyway), ebay will pull listings immediately. Panerai used to even enforce their crown protector design, some may remember the funky weird crown protectors they had on the homages for a while - not anymore.
Hard to get upset about the fakes on ebay when Panerai won´t lift a finger to stop it. I just feel bad for the buyers.
