A respectable forum like watchesuseek or rolexforums. there are respectable sellers selling pateks on both as we speak.
The only issue is, you won't have a reputation on there so buyers may be wary. But go on there, engage. Be as transparent a possible with the papers, authenticity, receipts etc, and you should be good. It's a nice direct way to sell it with no middle man cut. So you'll need to price accordingly with that in mind.
