1:1 Rolex Replicate has the laser edged logo on the crustal at 6. this is nothing new and not a good tell tale sign. Clone 3135 movement which is very similar to the genuine 3135 movement are also offer with these Replicates. To the untrained eyes, these replicates are no different than the genuine. usually, on the appearance. bracelets ( edges rather rough, gap is wide) , pearl ( brownish, no lume), bezel ( numerals are not deep, dull colour), date wheel overlay are the areas that can tell it is fake or genuine or not ..
But, some people will go all the way to mod these watches ( not necessary to sell but for their hobbies and interest ) buying genuine components to fit. So again not a reliable source to identify fakes. That's why I ask for serial number, as I as I know, this is one area that is very sure no fake can imitate.
