greetings from the south..

I joined recently. I just got my first high end rep, I think. (PAM682). Love the watch. I have a couple of questions that maybe someone can help me with. I have been looking a noob and ar watches they seem to be worth the money. Where is the best place to find the newest ones and highest quality ones, I am liking the 904l stainless stuff. Are the watches the correct weight? Also is or can these watches be waterproofed? Not for diving, but maybe swimming?
