Apple will reportedly have enough sapphire glass for both of its iPhone 6 models as well as the iWatch in 2014, based on the latest supply chain check at the company’s sapphire glass manufacturing partner GT Advanced done by analyst Matt Margolis for Seeking Alpha. “As a result of my most recent supply chain check I believe that the Mesa sapphire operations will have ample supply to cover the iWatch, the 4.7″ iPhone and the 5.5″ iPhone with full sapphire cover glass in 2014. Additionally, the maximum sapphire screen capacity of the Mesa facility is likely to exceed 200m annual units.”
