I recent purchased a Jaeger Le Coultre Reverso through a private seller on Chrono24. At first I was very reluctant but after a few emails with the buyer I went through with it. I am more than happy with the results especially since the seller had no reviews or ratings. I believe you need to do your homework and ask questions to feel it is what you want and whether legit. I would use Chrono24 again. The experience I had was great.
