The rule of the day on watch forum classifieds seems to be that sales put the seller in the position with the most leverage. Its the opposite of eBay, and thats why people who sell on forum, sell there. They want the control. Its understandable, they just are limiting their market potential (risk) for the sake of safer sales (reward).
I dont like chrono24 at all. never got good vibes from there. Also, most listed stuff is overpriced there imo.
