AR Question - Rolex ProHunter

[imajedi]

I've seen pictures of this ProHunter GMT on both here and RepGeek (posted by projectologist).  The AR just seems to be incredible.  Not only does the crystal vanish but the cyclops seems to retain the "black hole" effect.  I have a ProHunter sub that I don't wear purely because the crystal is terrible.  The glare off the cyclops is so bad I can't even read the date unless I turn it to just the right angle.  I'd love to somehow get a crystal similar to the one on Projectologists ProHunter GMT on my ProHunter Sub.  Does anyone have any idea how to get this done?  In his post, Projectologists lists that the crystal was double AR coated on both sides.  While I believe it was my gut tells me that the crystal must have also been additionally AR coated under the cyclops to add the blackhole effect.  I was thinnking that ideally I would take a crystal that already has an AR'd cyclops, like the ones from BigCrown (I actually have one already) and have the whole thing additional double AR coated.  The problem is that it's a gen spec crystal and I'm not sure if that will fit in the noob sub, which the ProHunters are based on.  Anyone know whether a gen spec crystal can be stuffed into a noob sub?  I thought I saw a tutorial on here where someone shows how to take apart a noob sub and replace the crystal with a Clarks (gen spec) crystal by remvoing it through the case back.  Anyone run across this thread?  Assuming it fits do you think that double AR coating a BigCrown "black hole" crystal would give me a similar result? 

 

My other option would be to take out the crystal that came with my ProHunter sub and have it double AR coated but my gut tells me that's not going to give me the "black hole" effect.  Can someone who's knows more about AR than me help guide me in the right direction or just chime in with your thoughts?
