Yes, I have. I bought one of my Chanel J12's from them about 18 months ago. It was a perfect, easy transaction, though I have to admit they weren't super nice on the phone (which you'd think they would be given the dollars involved).
When the watch arrived, they hadn't wound it, as it was an automatic, so I had to figure that out myself which wasn't hard. I also had to take it to a local jeweler to be properly sized and have several links removed. Of course, you are getting a watch without an official manufacturer warranty, only Authentic Watches in-house warranty, so if anything goes wrong with it, you need to go back to them. I have had no issues in the 18 months I've owned mine though. It's perfect.
