The Apple Watch could not meet this basic requirement until you took the watch back to you. The screens of Apple's timepieces were also dark. Fortunately, Apple corrected this gap by displaying a "always lit" Retina display on the 5 Series - frankly, the main novelty of the slight improvement over last year's Series 4, which now replaces the new watch. But Apple has introduced a new problem: a battery that deflates too early? More on that in a moment.
