Finally, Apple Watch has an ambient light sensor under the glass. This sensor samples the environmental light falling on the screen and automatically adjusts the brightness up or down to improve viewing comfort so that the screen isn’t too dim or too bright, based on where you are. An ambient light sensor also helps regulate the power that the display uses, thus squeezing more battery life out of the watch.

In fact, beginning with Apple Watch Series 5, the Retina screen is always on — just dimmed — until you turn it toward your face to read the time or other info. In previous Apple Watch models, the screen goes black when you’re not looking at it, and it takes a split second to wake up and turn on when you turn it toward you.
