Hi, I found a vintage watch I love on chrono24 and would like to put in an offer. I am satisfied with the dealer and watch’s authenticity. I have asked for some more pictures and video and information on little details I noticed and everything looks great. I would like to offer 10-14% off the price. I think the reason I want to do this and my best rationale to the seller is that I want to be able to get most of my money back if I end up having to sell it for some reason. The best data I can get is probably how long this particular watch has sat on chrono24 without a buyer. The seller is also listing on eBay and it looks like the item has been up on eBay since at least July. Is there a way for me to tell exactly how long it has been up on chrono24? Or eBay? Thanks!
