I did a little research(probably far too little in hindsight) in my efforts to get a 1:1 "Super Clone" Rolex Submariner. I came across Bestreplica.sr and was impressed by their website and all the marketing it contained. I went to (what I am now being told was a fake review site), and thought I adequately vetted this seller. I opted to pay $300 more for the piece of mind of having visa protect my purchase. I ran into problems in placing the order (had to place it three times due to credit card processing issues on their end). It spent over a month in "Quality Control" between the second and third orders, then I feel like I had to pressure them a little to get the DHL tracking numbers. While waiting for it to ship, I came across this website and a couple others and was sure I had made a huge mistake. I was already contemplating contacting my credit card company to cancel my order, when it finally shipped. It did track and arrive fairly quickly once picked up. The watch was well packaged to avoid any customs issues and I have to admit the watch seems to be everything they promised. It looks great. The weight is exactly right. It has all the correct markings and appears to be flawless. Now I have no idea if it's really 904l and I haven't taken the back off to look at the markings on the movement yet (I will). I also can't tell you what might have happened if I paid by wire (which they clearly prefer), but it appears to be a great watch in all aspects. I also cannot tell you if there is a difference between this and the $500 to $600 "super clones" I have also come across since then, but I can say they delivered me a product that seems to meet all their promises. They did not take my money and "go dark" like others have stated. User's recommendation: If you are not in a super hurry to get the product you should be OK.
