I personally wouldn't like the feeling of wearing a watch to sleep, so I wouldn't use a smartwatch for sleep tracking.

I use my Apple Watch as a simple nightstand and alarm clock. It works well.

I love the fact that (while I'm doing a similar thing with my phone, and would also describe it as "a basic..."), the phone/watch is probably a million times more complex than any previous nightstand / alarm clock around.
