I'm pretty new to this too, but I have bought from at least half a dozen dealers. Not all of them trusted by this site or RWG, but most are. I've had mixed results, but overall I've been happy (lucky) with my experiences, save for a few duds recently.
The green calibre 16 is one of the best I have received, and I'm sure it would have been the same had it come from any of the trusted dealers, as they come from the same factory after all.
Trusty is a trusted dealer on RWG
www.trustywatchguy.com/ , I got a dud cheapy from him recently, when I contacted him by email, he was straight back to me to sort it out. In the end I didn't see it as worth while to send the watch back to him for replacement, so he offered me a large discount on my next purchase.
I've also had good experiences with non trusted dealers, but as others will tell you, why buy from them when a trusted dealer has the same product. That's a fair call and something I think I will stick to from now on, as I just received product from a site call aoobuy.com. The goods arrived ok and I am happy with them (a couple of tag grand carrera 36's), but the day after ordering, the website has disappeared, and it's still not up. So I was a bit worried about my purchase, but he emailed me a tracking no. and they did arrive. But it could have easily been a different story, as in, I paid the money and then nothing.
So just stick to the trusted dealers and you will be fine. If you want to go with one of the trusted dealers on this site, I've purchased from Puretime and Trevorwatch, both were very good to deal with.
