Toughened Smartwatch Glass Unveiled
Corning's Gorilla Glass SR+ for wearables is scratch resistant and less prone to cracking than sapphire crystal.

(CCM) — Corning has developed a new type of glass composite intended to make scratched smartwatch screens a thing of the past. Gorilla Glass SR+, announced yesterday, has been specifically designed for smartwatches, fitness trackers, and other wearable devices. The material significantly reduces visible scratches while delivering optical clarity and touch sensitivity, the company claims. Apparently referring to the sapphire crystal screens used in some Apple Watches, Corning said that "in laboratory tests, Gorilla Glass SR+ demonstrated superior scratch resistance approaching that of alternative luxury cover materials while delivering up to 70% better damage resistance against impacts and 25% better surface reflection than those alternative materials." The company added that reduced surface reflection can lead to longer battery life and improved outdoor readability. Gorilla Glass SR+ is commercially available now and will start appearing in products from global brands later this year.

Last month, Corning unveiled Gorilla Glass 5, a new generation of toughened glass designed for smartphone screens that can survive being dropped facedown from a height of about five feet. This and previous generations of Gorilla Glass have been used in more than 4.5 billion devices worldwide.
