··Omega Qualified WatchmakerWhat is the purpose of the external AR on a crystal
It makes the crystal virtually disappear, making the dial much more legible:
, does it not undo the benefit of a sapphire crystal?
No.
Seamaster 300MC - is this a scratch on sapphire or AR coating?
It makes the crystal virtually disappear, making the dial much more legible:
No.

Thanks for the response but this still leaves me slightly confused, the crystals on a watch get treated with AR to improve the clarity of the dial, yep okay accept that, but why put a soft coat over the top of a hard crystal, under the crystal I can understand but a soft scratchable coat outside the crystal confuses me.

Not sure why this is confusing. Putting it on both sides is far more effective than on just the underside.
The coatings are quite durable actually. However, if someone is offended by having it on the outside, it is easily removed with a bit of diamond paste - takes just a few minutes and I have done it many times. As I've said many times before when this issue comes up, putting on both sides makes the most sense. People who don't want it can remove it easily, and for those who do want it, they get what they want. If it were only on one side, a whole bunch of people who want it on both sides are left out.

·So what’s your cutoff? $5,999? $6,999? I understand a lot of you spend way more on a watch and that’s fine, but for $5k I expect a watch crystal to not scratch easily ESPECIALLY IF NO HARD KNOCKS WERE ENDURED. Is that so unreasonable? Read 2 posts above yours.
If I knowingly scratched it then I wouldn’t make this post. A lot of you are not addressing the question posted here.
The real problem is that you aren’t accepting the answers. You are unable to admit you screwed up. Get off your high horse and accept the facts as they are!

·It actually does make a big difference when the AR is applied on both sides of the crystal. I notice this the most on my SMPc. The crystal seems to almost disappear and the black dial almost looks like it is floating in the case. Hard to explain, but the effect is absolutely there.

Sorry for being so thick but this now makes perfect sense, thank you

Really? Maybe you can't read simple English. All I wanted to know as clearly indicated in the first post was whether this scratch was on the sapphire or AR. Some said AR and one person said sapphire. Then, you went on to tell me about a $420k watch and alluded to how a $5k watch will be more susceptible to crystal scratches. So tell me, who's on the high horse here?
Also, show me where I'm unable to admit fault here? I'm beginning to think you really have a comprehension issue here. I'll say it again and I'll make it as easy for you to understand as possible...here goes!
To my knowledge the watch crystal never made contact with anything. Does that mean it didn't make contact with anything? Of course not. But it also means that the AR is somewhat delicate if it scratched without anything presumably making contact with it - I would hope anything significant enough to scratch the sapphire or AR would have alerted me. That aside, I still asked the group if it looks like the scratch looks to be on the AR or sapphire. Hopefully you get it now.

·I’ll just add my experience - when I first got into watches many years back, my second Omega was a black SMPc. First watch with double sided AR - and it was gorgeous. I was a little obsessed with keeping it smudge free (I assume all newbies go through this phase?? ), and while at work, after drying my hands I had a habit of using the now-wet paper towels to give the crystal a quick wipe - something that wasn’t an issue on my 2220.80 which has no outer AR coating.
What I didn’t realize was that the coarseness of the paper (I mean, it was more like semi-absorbent sandpaper) was putting marks into the SMPc’s AR coating - so after maybe a week or two, I started to notice hairline swirls that you could only see at specific angles against a light. Sort of like the swirl scratches you get on your car’s clear coat over time from washing.
anyway - all that to say - the coating is indeed very durable, but it’s still possible to get light scratches on them without ever really noticing what the thing that caused them was. It’s just part of living with a watch with AR coating - it makes the dial on my POLMLE pop like crazy but I also see the little marks. Still love it, so just gotta be mindful about it or remove it like others have mentioned.
¯\_(ツ)_/¯

·I once saw a $420,000 platinum wrist minute repeater...
That watch sir, was not designed for a man who opens his own car door.

·Εσύ τι θα πρότεινες? Πάντως μαλάκια δεν είναι να πληρώνεις ένα ρολόι 4000 ευρώ και να έχεις γρατσουνιές? Αν διώξεις το Ar coating έχει μεγάλη διαφορά?
