Making the watches Wear-aware. so that it knows when it's on the wrist and when it's off. Just like APPLE AIRPODS

Not sure if this is already there. But it'd be great to see the watch be Wear-aware.so that it knows when you are wearing it and when it's off.

Just like APPLE AIRPODS are.

So many features/settings can make use of this. like MOVE / smart notifications.

maybe the heart rate sensor can do this on wathces with little coding.

Examples:

My FR245 will just keep on giving Move alerts even when i'm not wearing it. 

Or I would love to have the option to disable the display of notifications when i'm not wearing the watch.

Thank you!
