Consumer Reports tests Apple Watch
Consumer Reports tested the watches for abrasions and scratches using "pics" that were hardened to a certain degree. The Apple Watch Sport screen made with Ion-X glass survived a pic hardened to match a pocket knife. It took a pic as hard as a mason drill bit to afflict damage to the screen. The stainless-steel version of the wearable employs a sapphire glass screen that wouldn't scratch even using the hardest pic available to Consumer Reports testers.
Apple has not advertised how water resistant the Apple Watch is. But based on Consumer Reports' tests, the timepiece can survive after being submerged to 3 feet of water for as long as 30 minutes. And using Consumer Reports' highest tested heart rate monitor to test the accuracy of the Apple Watch's heart rate monitor, both devices had essentially the same readings tracking someone on a treadmill moving at various speeds.
The Apple Watch continues to be tested by the magazine which means that we can expect more videos like this one in the near future. But for now, the Apple Watch appears to be tough, accurate and can live through a submerging.
