사파이어 글래스 탑재된 럭셔리 에디션 애플워치 '안 보인다.'

'긁힘에 강한' 사파이어 글래스 재질로 제작된 사파이어 글래스 에디션 애플워치가, 일반 애플워치의 강화 글래스 대비 선명하게 보이질 않는다는 결과가 나왔다. 상단 첨부 이미지 처럼 (우)사파이어 글래스는, (좌)보급형 애플워치의 글래스 보다 한눈에 봐도 선명하지가 않다.

디스플레이에 관하여 권위있는 매체인 'DisplayMate'에서는 사파이어 글래스를 탑재한 애플워치의 시야각이 좁아지고, 반사율이 일반 유리 글래스 대비 2배가 넘어 흐릿하게 보인다는 문제를 제기했다.

Screen Reflections The Screen Reflects Ambient Light, which washes out the Image Contrast and Colors. The Average Reflectance is measured with an Integrating Hemisphere and Spectroradiometer. The Mirror Reflections are measured with a highly collimated beam of light and Spectroradiometer. The Reflectance of Sapphire is much higher than Glass.

고급형 애플워치에 적용된 사파이어 크리스탈 글래스가, 긁힘에 강할 뿐 아이폰과 아이패드에 탑재된 강화 글래스(Ion-X Glass)보다 가독성에 문제가 있다는 얘기다. 이로써, 새로운 아이폰6S/+에 사파이어 글래스가 탑재될 가능성도 희박해졌다.
