Is Apple Watch sport using the dual ion exchange glass? i think it is still using 6 -class glass
Got a tip for us?

New Dual Ion Exchange Glass

AW Sport uses Ion-X Glass which is different from this new Dual Ion.
It won't matter though how tough Dual Ion is. Even if the screen was somehow made of air, I'm sure someone out there would manage to scratch it and complain.
Probably true, but will never be confirmed by Apple or Corning.It uses Gorilla Glass 3. TheWatch was developed before Gorilla Glass 4.
I have been researching this very question like mad, and I have not been able to find anyone else doing anything except regurgitating Apple's claim that the new phones will have the "strongest" glass of any smartphone in the industry. To me also, not having to use a screen protector for the first time will be a very significant advantage. I currently have the Zagg glass on my 6 plus, and while it's a good protector, I would much rather not use one at all. I am extremely careful with my phones, but I am also extremely OCD when it comes to even the smallest blemish. Any scratch would drive me absolutely crazy. But, at the same time, I really want to feel the 3D touch when I use it like in the Apple watch (which I don't use a screen protector on but have decided that a scratch on the watch is inevitable, and putting a case or screen protector on a watch, for me, is a bit too much); the small "haptic" feedback is awesome. Anyway, we shall see when the scratch tests and such come out just how durable the screen really is...

"Thirty-one of the 50 states provide parts, materials, or equipment to make Apple products. This manufacturing spans an incredible range of industries with suppliers from coast to coast. For example, some iMac models are assembled and tested in California. Many of the processors that go into Mac are from Arizona. Indiana contributes sophisticated manufacturing using high-performance alloys to ensure that our products hold up under tough conditions. Kentucky continues to be a major provider of glass for iPhone and iPad. And the cardstock for our beautiful letterpress cards comes from Wisconsin."
One of Corning's (maker of Gorilla glass) biggest factories is in Harrodsburg, KY.
As long as there is oleophobic coating on the screen, you will get scratches. Extremely scratch-resistant glass/sapphire can prevent serious scratches beneath the coating, but the coating is and probably always will be the weakest link.
Except it's not, the 6s has a NEW DUAL ion exchange glass. It's not comparable to the Apple Watch, Unless it was the iPhone 6.
You have it backwards. The oleophobic coating is the hard part that resists scratches. Has the 8-9 hardness, and will get scratched by sand. Sand, mostly silica quartz also has hardness of 8-9. Keys, coins other typical metals are softer in comparison and will not scratch.
The ion exchange in the glass surface provides the strength against breakage. Hot glass is immersed in potassium ion bath. The sodium ions in the surface of the glass migrate out and are replaced by the larger potassium ions. When the glass cools the larger potassium atoms caught in the crystal lattice structure cause a compression in the surface of the glass. This imparts the strength against breakage. This layer has a 6.5-7 on the hardness scale.

Wow, thanks for the awesome explanation. I'm happy to find out that I was completely wrong... but now I'm a bit confused. If the oleophobic coating is the scratch-resistant part, then it doesn't matter how scratch-resistant the glass underneath is, unless it's more resistant than the coating. Correct? In which case the talk about "stronger" glass has nothing to do with scratch-resistance and everything to do with preventing breakage.
Maybe I've just been making bad assumptions for all these years about the glass that is used in smartphones...
The heat and chemical tempering done to the glass does add a bit of hardness. Untempered glass usually 5-6 on MOHs scale. By inserting the larger potassium atoms in the crystal structure, when glass shrinks those atoms exert pressure on the molecules next to it, making that layer compressed. So the outside skin of the glass on all sides is under compression. This helps it resist impacts, hammer blows, and bending force. If you damage this outer skin lets say with a deep scratch that penetrates to inner less compressed glass that is where the glass will fail break. That's why once a phone gets a good scratch it breaks quite easily.
The oleophobic layer does two things. Firstly it is harder and resists scratching even better. This helps prevent the scratch damage to the compression layer below. However the oleophobic coating is quite thin, and can wear off in time. Especially if solvents are used to clean the screen. So no alcoholic, windex or other agents on a regular basis. The wipe down before placing a cover shield in not a problem.
The second great thing about the oleophobic coating is it resists wetting by water and oils. So fingerprints don't adhere as easily. Oil and water bead up, don't spread out as easily.
Sapphire is a solid 9 on the MOHs scale. Diamond is 10. So in it's natural state, sapphire is as hard through and through as the best oleophobic coating. The problem is sapphire is more brittle than the glass. It breaks more easily from drops, blows, any impacts. Gorilla glass is quite a bit stronger in resisting impact damage.
I suspect that this actually had more to do with Apple not using Saphire last year than just production volume. They were trying to find a formulation that was less brittle but still as hard.
Strength against breakage is different than hardness, resistance to scratching.

I'd anticipate these will be like the latest Samsung edge phones', mainly better at drops but only slightly better resisting scratches compared to the prior model. Samsung's own case scratched their phones up and they had their own 'scratch-gate' scandal. I'll be putting on a screen protector as usual, unless I hear people say they're not seeing scratches / micro-scratches with real life use (I don't really think the way people test things on YouTube is terribly useful). Those of us who are a little OCD like me, won't really be able to really avoid screen protectors until Apple uses sapphire. I almost never hear of Apple Watches with sapphire getting scratches, unlike their Sport counterparts.
You shouldn't be so accepting of what people spew out on the Internet without sources, yes he has a link there but it says nothing to back up any claims made, it's irrelevant information.
Its the coating that scratches, but its the same thing to the user as you still have to look at the scratched coating.
I haven't had a screen protector on any of my phones in years and have never had a problem, but man I'm always wiping off smudges. 
I am more than willing to hear any information you have that disproves the information he provided.
I got a pretty good scratch on my Apple Watch Sport in the upper right corner. Not sure where it's from, and I am very careful with all my apple things. I hope this new glass on the 6s Plus is tougher than what we have had in the past. I too do not like screen protectors. The thing is, even if I had a protector on this watch- it still would have scratched since it's in the upper right corner and those protectors are made square due to the design of the screen.
I have not presented a claim to anything, but you have. The burden is on you to prove that claim, not for everyone to assume that claim is true and for us to disprove it. Until you present some evidence that shows oleophobic coatings provide scratch resistance I can not asses my own argument to either agree with the evidence you have presented or provide my own evidence to the contrary.
You most certainly have presented a claim. Your claim is to spread a seed of mistrust and to question the veracity of information I have provided. You do so without providing any logical reasoning or evidence to support your claim. Further, you even have the audacity to claim that I and others are under some sort of obligation to provide you evidence so you may judge us and our discussion.
Well who made you high lord and Chief Justice to preside over this thread. I suspect no one but yourself. Your arrogance is astounding. I am not trying to sell something or persuade anyone about anything. And I particularly don't give a rodent's hind quarters what you think.
You are under no obligation to believe any of what I have said, just as I and others are under no obligation to provide you with any corroborating evidence, especially given your condescending and arrogant demeanor. Everyone here has the same resources to research and find information regarding coatings, glass production and other topics.
For those of you still interested in the subject, consider that placing any coating that has lesser hardness rating on top of something harder works against the idea of reducing scratches. A quick search will reveal to anyone two points. One that there are a number of companies providing coatings to enhance surface hardiness. And two, that being proprietory information, exact details are hard to come by on the web. But you will come across clues that the glass doesn't get harder than 7 on the MOHs scale and that coatings take it to 8-9. Of particular interest is a test that Corning did I saw on you tube that showed glass half with coating and half without being scratched by sandpaper. The amount of scratches on the non coated side were very convincing that the coating enhanced the hardness. Go find it if you are interested.
