Gorilla Glass SR+

It is no secret that wearable devices take a beating. They are constantly exposed, being subjected to not only the elements but also the objects you encounter everyday. There is nothing more frustrating than your watch ramming a door handle as you walk by or scraping along the wall when you reach for something. Sapphire glass is used for numerous of wearables for just that reason – sapphire is the second hardest material, only behind diamonds. But sapphire glass isn’t perfect. To start with, it is expensive (estimated to cost 3 to 4 times more than typical Gorilla Glass) and heavy (67% heavier than typical Gorilla Glass). Also for how great it is protecting against scratches, sapphire glass shatters very easily. Finally, the optics of sapphire glass, especially in direct light, are not nearly as good as traditional glass products. Looking to address all of these issues, Corning has developed Gorilla Glass SR+.
