Use as a Flashlight
The Moto 360 can turn into a flashlight if you need to see what you are doing. It's not the brightest, but it is handy for lighting your way in a dark hallway or to make you more visible while walking at night.
Swipe down from the top and tap on the flashlight to turn on the Moto 360 flashlight. You can turn it off the same way.
I recently used this feature when I crashed at a friend's house to avoid bad roads. It made navigating dark hallways at night easier than flipping on switches and waking up his family.
