Professor Steve (if I'm not mistaken) is one of the supporting vendors here. He is a magician who will take your $120 USD and will turn it into a beautiful gen-like crystal with double AntiReflective coating. Apparently, his crystals do have LEC (but you need to ask for it)

I was told that profs crystals should be good but they scratch faster than a gen is it true?

Gen don't have double AR. They actually only have AR for the Cyclop, the rest of the crystal has no AR at all. That's what creates the black hole effect. I think rnrprof has both gen like and double AR but check with him

ive noticed a lot of ARFs have been undermagnified. Would this be fixed by replacing the crystal? or is it a matter of distance from crystal to datewheel.

Many of the ARF watches have fonts that are bold. Also, some of the rep crystals don't have the exact 2.5x cyclops magnification. This exasperates the issue. As long as you have the right date font size, both Prof and gen crystal (they are 2.5x cyclops) will look gen-like.

Yes I have both complete ar and only under the cyclops and under the crystal
Someone mentioned that Rolex doesn't AR the crystal itself.

Can I ask - which crystal is most gen like? What's the benefit of the other one? (thay is. If the one with no AR is more gen like, what is good about the double AR?)

Someone mentioned they may scratch easier? Is that accurate?

His 2xAR crystals are amazing and literally are invisible on the watch. Looks like the crystal fell out and you are looking directly at the dial. The black hole crystal has AR on top and underneath the cyclops giving you double AR on the cyclops only. That’s why it looks like a black hole compared to the rest of the crystal. It’s exactly like a genuine and 1/3 the price. Yes double AR crystals can scratch because of the coating on top but it’s no more prone to scratches that a crystal on a Breitling or something that comes with double AR from the factory. Rolex do not come with double AR. It is probably the most important mod you can do to a replica 116610 sub because it’s by far the biggest and easiest tell on a rep, the lack of the obvious black hole.

the prof crystals are at the level of the gen and I dare say that well above 99 x percent of the crystals minted by the gen clocks. the problem is that you have to be careful, one day a grain of sand is in your ballets when you clean the glass it will ruin it
