I firmly BELIEVE you can build a replica of EQUAL quality to that of a submariner. WM9 is an example of this, paired with a chronometer grade movement and what does a Rolex sub REALLY offer over this? 904L isnt even practical for the average buyer, heck even a professional diver needn't have it. But get into more sophisticated movements such as the GMT with adjustable hour hand and you cant really find that anywhere else (as far as I know) As far as quality of gold and jewels, well then you cant match the quality in a replica to the genuine article. For sports models a Rolex rep gives the genuine article a run for its money and is kind of hard to justify paying a genuine price for something that is all steel with a date. This fact im sure has Rolex scared as theyre even going as far as to file a lawsuit against ebay for not stopping enough counterfeit trades. Dont believe the marketing about taking a year to build one as Rolex produces about 2000+ watches a day. Youre buying the brand, prestige, and exclusivity of a $500 watch for sixty-five hundred.
