·The OP has no need to worry or be dissapointed. It is fixable at about £135 sterling or $200 plus USD not the end of the world considering the cost of the watch.
Scratched Crystal on PO 8500

·I know what he meant. He said,"I haven't done a side by side comparison" (top surface coating vs under surface coating). All I was trying to say that Omega made the decision that light penetration was better with the TOP surface coated. Right or wrong! I don't know where you get your percentage comparison, but with the percentage of light being reflected off the un coated top surface, I'd have though the percentage difference would have been greater. But what do I know? I will say that an uncoated sapphire crystal is more effective at absorbing light than a tempered glass one. Maybe the coating (inside or outside) is a bit of overkill!

·My opinion is that AR sould be under the glass only. No point in sapphire if coarting scratched.

Tempered glass? Got me on that one.....
But for real in the article I linked to it states:
"Breitling sapphire crystals are coated on BOTH faces, this costly choice offer the lowest reflection on the crystal. Most watch brands only coat the INTERNAL face of their crystal : this of course cut by half the amount of reflection , but still the glare is close to 5%, with a double face AR coating Breitling offers a glare under 1%"
Now I'm not sure if those percentages are close to the findings on Omega singe and double AR coated crystals but my subjective findings is that while the outside AR is noticeable side to side it's not something you perceive at first glance, whereas scratches to the AR are much more noticeable.
Also, to wit; a lot of times differences in measured percentages and factors aren't nearly as perceivable in the real world. Kind of like decibels in audio - how a 10db increase is measured as 10x the sound pressure level but only perceived as 2x as loud by the listener.
And I think you and I were focusing on two different parts of @wsfarrell statements. I was focusing on the first part, "Kind of boggles the mind that people put AR coatings on the outside of vulnerable crystals."

·Perhaps Omega is following this thread, and will accede to the opinions offered that the coating should only be on the under side. HAH! Like that's going to happen! Clarity GOOD! Scratches BAD! The answer is to not smack your expensive Omega around.

·again a chip isn't the same as a scratch. blaming a chip on the scratch resistance of sapphire is like blaming a car dent on the paint

·what a bummer... scratch on the PO is like what they said, it may be just the AR coating if its unnoticeable. Service will take care of it too..

It could of been a scratch not sure but then it could of been a chip it was to small to see. A chip is a figure of speech. Anyway this thread proves that a scratch can appear on a sapphire crystal even though it may just be on the surface of the AR coating.

··Not in LA anymore.I found this interesting, and pertinent to the discussion. Both bits of text are from Rolex's official brochure for the Explorer I
When you're considering buying the watch, Rolex wants you to believe the crystal is scratch-proof. And if you come back to complain about the scratch in the crystal of your shiny new Explorer I, the crystal becomes merely scratch-resistant.

·I recently had my ploprof 1200 returned from Omega for full service. I also have a very small scratch in the AR. Have to look hard to find it. They wanted $500 to replace crystal.

·I had the exciting opportunity of testing a sapphire through some crazy tests which ended with them giving me a hammer to test its strength. The sapphire ultimately shot across the room multiple times unscathed...until the 4th hit 👍

·If that was a sapphire watch crystal? Or was it a sapphire stone? Among gems, stress amounts to abrasion, indentation, and shock. Diamond (for example) is understood incorrectly by some people as being indestructible. It is NOT! Among gems, it is the most resistant to indentation and abrasion. But it is NOT the most resistant to damage from shock! Jade would be far more resistant to damage from a hammer than a diamond, OR a sapphire. The disadvantage with jade is that it is NOT the most resistant to indentation and abrasions! Sapphire would be more resistant to abrasion and indentation than jade. But the sapphire likewise would be less resistant to damage from shock (as in a hammer), than jade!

·Sapphire is cheap to make, it's all man made and the cost is virtually nothing.
Just checked the price on a 2,4mm thick Sapphire crystal, not necessarily for this watch but simply a thick sapphire replacement crystal. Price? less than 10 Pounds...
Someone is making a good markup on factory parts.

Is that just a flat crystal with no AR coating? If so, not apples to apples...

·No AR, but I know of a company that offers AR coatings for around 25 pounds.

Me too, sapphire is a finger print magnet. Also plexi is easy to polish, cheap to replace plus cause it protrudes from the bezel the bezel doesn't get as damaged cause the plexi gets the hit first.

AR is only one factor. Flat crystals are much cheaper to produce than profiled crystals are, so not really a good comparison as all the Omega sapphire crystals on modern watches are profiled.
Certainly they are making money on them...they are a business after all...

·Without a doubt, nothing wrong with making a profit.
I was simply trying to highlight that sapphire by itself is not expensive.
Now, what is going on that you are still here at 03:00 Eastern Time? It's not even New Years eve... 😀
