Apple Watch Sport Ion-X Display Glass Gets Scratch Tested [Video]

Posted by · 14946 views · Translate

Check out this video showing a scratch test of the Apple Watch Sport's Ion-X display glass.

The 38mm and 42mm glass display covers were provided to Unbox Therapy by Sonny Dickson, who has obtained authentic Apple parts in the past.

Ion-X glass is the same material used in the windows of space shuttles and high-speed trains. This glass is thin and light, yet surprisingly strong — five times stronger than regular glass. There are many ways to strengthen glass at the surface, but Ion-X glass is hardened down to its molecules. During the manufacturing process, the glass is dipped in a 750-degree molten potassium salt bath. That’s when ion exchange takes place, with the smaller sodium ions being removed from the glass and replaced by larger potassium ions. As the glass cools, these larger ions create an extremely hard surface layer that is resistant to scratches and impact.

The scratch resistance of the display glass is tested using a key, a knife, steel wool, and two types of sand paper.

There is also a good side to this story, sapphire is a crystal just like diamonds and I worked with diamonds for many years, the thing is that the harder the substance is the easier it is to break ( that's why every diamond dealer office have a special wall to wall carpet) I've seen first hand what happens to a diamond that falls on concrete, if it hits the bottom point of the diamond it breaks right off and if it's a heavy enough diamond it will totally shatter, any way you get my point, it's les likely that the ion glass will break when you accidentally drop the watch when you take it off for charging or hit a wall by a mistake then the sapphire will.

Lol. This guy wouldn't know steel wool if he pulled it out of his ars. And saphire coated? It's pure aspire on the more expensive watches. Not saphire coated.

It will be obsolete next year no need to test.
