Best place to buy and sell IWC watches

I'm new to the forum and I have quite a few IWC watches, but I have one in particular that I'm trying to sell. I know this is a non-commercial forum and there is no buying or selling on here, but other than chrono24 and, obviously, eBay does anyone have any advice for selling and getting to actual collectors? I have a feeling that the watch I'm trying to sell will be a very, very collectible item.

Thanks,

David

I'd go with Chrono24.

Oh well, Im just dying to know what you’ve got to sell,
