Guest Posted June 8, 2013 Report Posted June 8, 2013 I tried toothpaste, Windex, soap, hot water, pledge, etc... The persistent smudges still remain. I can't get a good photo but I hope you know what I'm talking about
jpz5142 Posted June 8, 2013 Report Posted June 8, 2013 Couple questions, is that sapphire or plexi? If sapphire did it come with an AR coating? If so I wonder if those "smudges" are your AR coming off. If plexi find a product called PolyWatch and polish your plexi.
cc33 Posted June 8, 2013 Report Posted June 8, 2013 +1 looks like the anti reflective coating on a sapphire crystal has worn off it has to be re-ar'd if that's the case..
Guest Posted June 8, 2013 Report Posted June 8, 2013 Yes, it's ar'ed sapphire. Did the cleaning methods I used strip off the coating? It was like that before but when trying to clean, it got worse
jpz5142 Posted June 8, 2013 Report Posted June 8, 2013 It's rep AR, not that gen AR can't be scratched or removed. But rep is just that much cheaper.
freddy333 Posted June 8, 2013 Report Posted June 8, 2013 Do not use ammonia-based glass cleaners on AR. Once the coating is damaged/smeared, the only option is re-coating. Check with a local optician to see if 1 of their suppliers will recoat it for you.
Jkay Posted June 8, 2013 Report Posted June 8, 2013 AR is not expensive to re-do and yes, you've ruined it.
Guest Posted June 8, 2013 Report Posted June 8, 2013 Thanks guys! I thought I read that Chieftang didn't recommend opticians for AR. Any US based guys that do blue AR? I know Vac has a yellow tint.
panerai153 Posted June 8, 2013 Report Posted June 8, 2013 Mike, you got plenty to do already without getting into the AR business !!!! lolSent from my iPad using Tapatalk HD
SSTEEL Posted June 8, 2013 Report Posted June 8, 2013 Im intrested in what the whole process is for ARing a crystal. I never really looked into it. That makes two of us I'm unsure if its a dip/submerge process, spray, or a type of powder coat. Off to youtube to see if there's anything on these lol

Off to youtube to see if there's anything on these lol Just found this video on Youtube about AR coating. The dip method. Although not watch crystals, still worth watching. Then theres this other process too... And finally, again, whilst not a watch crystal, the following video show the spinning application, which in this demo is a microchip.

freddy333 Posted June 11, 2013 Report Posted June 11, 2013 Many optometrists will accept a watch crystal for AR. Of course, these are sent out to a lab for the coating (unless you know someone, the labs do not generally deal at the retail level). A local optometrist AR'd the area of the crystal below the cyclops on my TT GMTC
panerai153 Posted June 11, 2013 Report Posted June 11, 2013 Definitely the AR coming off. iruined a pair of glasses just like that thought the stuff was a smudge, went to work with plastic windscreen polish and in about 10 minutes the little smudge was a big smudge!! Lucky for you sapphire is hard, not like plastic eyeglass lenses, yours can be stripped and the AR reapplied.
Guest Posted June 11, 2013 Report Posted June 11, 2013 Thanks guys. I have a great idea. If sapphire is so hard and resilient, why can't they just put that stuff on top of the coating so it doesn't get scratched so easily
SSTEEL Posted June 12, 2013 Report Posted June 12, 2013 Thanks for the heads up Freddy on the Optometrists
sneed12 Posted June 12, 2013 Report Posted June 12, 2013 It's rep AR, not that gen AR can't be scratched or removed. Uh... gen AR most certainly can be scratched and removed.
Guest Posted June 12, 2013 Report Posted June 12, 2013 (edited) Uh... gen AR most certainly can be scratched and removed. I think that's what he said originally Edited June 12, 2013 by Guest
jpz5142 Posted June 12, 2013 Report Posted June 12, 2013 Uh... gen AR most certainly can be scratched and removed. Not saying that at all, just highliting that as with all things rep, AR is much cheaper than gen AR.
JR003 Posted June 12, 2013 Report Posted June 12, 2013 How did it get to this state? What substances caused the AR to be so damaged?
freddy333 Posted June 12, 2013 Report Posted June 12, 2013 Ammonia (as used in many glass cleaners) will remove most AR.
Guest Posted June 12, 2013 Report Posted June 12, 2013 It could have been a little bit of acetone though I'm not certain
Jkay Posted June 13, 2013 Report Posted June 13, 2013 Synthetic plush cloths (microfiber) used for automotive detailing will pull all the oil off your watch without harming it in any way at all. You shouldn't have to use cleaners for any bit of it.
david.the.marvelous Posted June 13, 2013 Report Posted June 13, 2013 I did this same exact thing on a watch that I have. Where can I get it re-AR'ed?
