Watch 47 - how does sleep work? Or does it?

I checked the watch before going to bed, There were no times ahown.
Again, the watch shows more sleep then possible.
this time I tried to pay attention to the times that the watch reported I was going to sleep and got up.
@~2300 went to bed
watch shows 0654pm
@~0700 got up
watch shows 0654 am

AGAIN Watch shows 11 hours 21 minutes of sleep (and 39 minutes awake) versus elapsed real time of 8 hours

Is this a vortex manipulator?
