Under normal circumstances, the screen will then show one of nine watch faces, each customizable. One will show the time alongside a brightly lit flower, butterfly, or jellyfish; these will be in motion, against a black background. This imagery had dominated the launch, and Ive now explained his enthusiasm for it. He picked up his iPhone 6 and pressed the home button. The whole of the display comes on, he said. That, to me, feels very, very old. (The iPhone 6 reached stores two weeks later.) He went on to explain that an Apple Watch uses a new display technology whose blacks are blacker than those in an iPhones L.E.D. display. This makes it easier to mask the point where, beneath a glass surface, a display ends and its frame begins. An Apple Watch jellyfish swims in deep space, and becomes, Ive said, as much an attribute of the watch as an image. On a current iPhone screen, a jellyfish would be pinned against dark gray, and framed in black, and, Ive said, have much less magic.
