1680 Posted July 15, 2013 Report Share Posted July 15, 2013 What crystal should it be? 116, 135, 127, 125? It's hard to tell if it's genuine when it's not in its original Rolex/Tudor packaging. Buy the seller! Quote Link to comment Share on other sites More sharing options...
clem2192 Posted July 15, 2013 Author Report Share Posted July 15, 2013 For a 16610 / 16613 Yeah I am worried but is an excellent price (if genuine) Ryan Quote Link to comment Share on other sites More sharing options...
automatico Posted July 15, 2013 Report Share Posted July 15, 2013 Pink sapphire is pink sapphire no matter who made it. The difference between genuine and aftmkt is in the polishing, inclusions, cut of the edges etc. High grade aftmkt crystals from trusted material houses are as good as genuine except for the coronet emblem on later models. I have compared sapphire 295 DJ crystals from ST, STI, JB etc with genuine and they are identical. Be careful buying crystals on eBay from 'fly by night' websites...buy from known sellers like Clark etc. Most high quality aftmkt sapphire 295 for DJ/sub are now $30 to $40 because of competition. They used to be $50 to $75. Quote Link to comment Share on other sites More sharing options...
clem2192 Posted July 15, 2013 Author Report Share Posted July 15, 2013 If aftermarket crystals are the same quality how comes a lot of Franken builds go the gen crystal route and say that the difference is noticeable?? What do we think about this one?? Quote Link to comment Share on other sites More sharing options...
freddy333 Posted July 15, 2013 Report Share Posted July 15, 2013 1680 has it exactly right. Always, buy the seller. A long-term, established Rolex parts seller with a lengthy track record is your only guarantee. Otherwise, the best way to ID a gen is by the 2.5x magnification of its cyclops (most aftermarkets have lower magnification) & the sparkle of the Plexiglas material. But, unless you have a known gen to compare to, it is very difficult to tell some of the better aftermarket xtals (like Clarks). Quote Link to comment Share on other sites More sharing options...
clem2192 Posted July 15, 2013 Author Report Share Posted July 15, 2013 Ok thanks guys, guess I'll have to let this go. How much is a top quality rep? This is around £70 Quote Link to comment Share on other sites More sharing options...
mymanmatt Posted July 15, 2013 Report Share Posted July 15, 2013 One way to to tell for sure is to rub your fingernail around the cyclops. The gen is very smooth on all sides. All the aftermarkets have a noticable roughness to them on the very lower edge. The aftermakets are not polished there. You will notice that on the clark crystal also.

When you find a high quality aftmkt crystal, buy a couple spares because the next batch may be from another manufacturer and not as good.
