A great site for locating watches, and reasonable prices can be found. The option of ‘suggest price’ is a little clunky. I have found on a couple of occasions that I send a suggestion and get no response from the seller. This essentially blocks you out, and has prevented me from actually buying a watch at the advertised price. It would be better if the offer lapsed after 24 hours.
I think the 6% commission is a little steep and perhaps pushing more private sellers to eBay high offers a little more flexibility on price with lower seller fees. Having tried to purchase a Rolex Explorer 1 214270 on Chrono24 and had no response from a price suggestion I subsequently found one on eBay at a good price. Finally, being in Europe I find phone calls to Chrono24 expensive. Their response to emails are slow. All that said, I bought a 2004 a Rolex Explorer 114270 from a seller in Paris on Chrono24 recently and found their communication and delivery quick and efficient.
