His point is merely that you should do your hw. This place is the best source of information. Bad experiences from josh are few and far between. One thing is to have a problem with him. Another thing is to have a problem with a watch. Often, dealers are very open about their shipping policies. If a watch has a problem or develops a problem the best ones on the forum will try to fix it. And it appears as if josh is doing just that for you. I also find it a bit disconcerting that the same problem happened to two of your watches. In my 3 years time here on the forum, I don't recall reading about anyone's crown stem coming out, but that's not to say it's never happened. Just be careful and mindful of all things when buying a rep and especially in how you treat it. We're all pretty forgiving in this hobby and have all shared similar bad experiences. We live and we learn, sometimes it's easy to blame a dealer for the problems of a watch, but enterign this game has it's risks. Just take it all in stride and pic a dealer that will take care of you when things DO go wrong.
Hope to see pics of the watches in question sometime! we love that kind of stuff here!
