Anyone participated in the trending online 'trade/sell your watch'?

Here is an example:

Curious what people's experiences are. I get the feeling that unless the watch you are trading is a Patek chronograph, Nautilus or a SS Rolex sport watch the amount you get will not be very satisfying. Like many of you guys, I am sure, I have accumulated a number of good Swiss watches over the years. I have read now in several business sources that this is a hot new trend ie the ability to easily offload your rarely worn watches and get a new one that is more desirable. I tried this once at the site Crown and Caliber just to see what would happen with a SS Girard Peregaux chrono. My recollection is that they give you an estimate range, in my case it was like $1100 to $1300. Of course they end up giving you the lower end of the estimate. Then after the mandatory cleaning/processing fees, I think I ended up with a little under $800 for my watch 3 or 4 months later. I have not bought a new watch in years, not because I can't afford it but just because it seems like a waste to have more than 7 or 8 at a time.
