Hi Vaj
I'm fairly new here myself. Prior to my first purchase I did alot of research, comparing watches, prices, dealer reps, etc. If you spend enough time on RWG you can educate yourself well enough to feel confident when you do make a decision regarding your first purchase.
You will see Joshua's name frequently when people refer to a reputable dealer.. I purchased a Submariner from him, asked him quite a few questions prior to , waiting for and after receiving the watch. Each time he responded in a timely, courteous manner. I could have purchased my rep for less money but I was willing to fork over a little extra to a dealer who represented himself as well as Josh did. I don't know which watch you're looking for but I highly recommend him.
And why are you even thinking of spending 900.00?????
Good luck
