I've bought three watches via Chrono24, two from Trusted Seller and one privately, and all three deals went through smoothly.

In the case of the private sale, the seller lived in the Manchester area like me. So we were able to meet up for me to examine the watch and come to a deal. I'm not sure I would have gone ahead if all communication was via email only.

For the two trusted sellers I checked whether they had their own websites and "bricks and mortar" operations, which both did. I also did some searching on the 'net to see what users on the various watch forums thought of them. They both had good independent reviews so I went ahead with the purchases.

You have to do as much research into the seller that you can and, as is often stated on this forum "buy the seller" before proceeding. However, based on my experience, I would use Chrono24 in the future.
