Hi and welcome!
Great to see you've done some research on your own. General advice is to read read read!
It's not always a mistake to PM a member with questions. The ones that took the time and write one of the classic review threads get noob questions by PM all the time though. It is undestandable that they will not answer them all. After they wrote the threads to make information available for all to read.
Now to your question: You will find a whole dealer section here on the main forum page (called "Watches, Clothing & Accessories"). All of these dealers are bullet-proof, which means RWG-Admin find them save to order from and should a problem arise that you cannot solve between you and the dealer members of the Admin Team will help.
Josh (Jos Nana) and BK (bklm1234) both have their own section here where order instructions can be found. Read them before ordering. Also make sure you describe exactly what you would like and do your research first. There are many versions of the most popular watches, be sure to know which one you would like. And bring loads of patience, Reps are not for the faint of heart.
Have fun!
