Is the display permanently on? Or does it go to sleep

Does this answer the question?

Apple Watch Keynote

Ambient light sensor. Same thing the iPhone uses to turn off the display when you hold it against your face. It just measures how much light there is. So covering the watch with your hand blocks the light. The sensor can't tell if someone is looking at the watch or not.

Yeah i know, but if you look at pictures of the apple watch, you can't see such a sensor. On my Iphone its pretty big, so i think you should be able to see it on the watch

I don't have to push the back-light button on my FitBit Surge when I'm near the street lights.

You seem to have side stepped the original joke in this thread. It was being noted that the time can be told with the sun without any kind of clock/watch. Backlighting (or a device's ability to show a display without doing so) didn't factor into it.

That's because you didn't get my joke about using street lights for a sun dial.

It seems like there is a new report out in the New York Times that states a previously unannounced option called time reserve mode where if the watch is critically running low on charge all other functions will be cut off and only the time function will operate. Granted this is not an option for those wanting to continue using all the functions I think it's still a welcome option.
