Definitely will have to, the descriptions on the pages are not helpful at all.
My buying process requires a lot of homework. I find a link on one of the larger TD's with a website, I make sure the factory is one of the well known factories. I gather photos of Gen's to compare. Then I search RWI for info and threads. I always spend $300 plus for the watches. I also look at the NWBIG list. I have purchased more than 60 watches since I joined with only 2 disappointments. because I didn't follow my own rules. Both were from a small unknown factory. Anytime a new version of one of the popular watches is released there is always a thread comparing the watch pointing out the flaws. Sometime major sometimes minor. If you stay with the good quality watches nobody can tell the watch is a rep. Most people don't even know the name of the watch other than Rolex.
Enjoy your time here and have fun.
