A fancy watch like the Apple watch or a luxury watch I wouldn't wear that way, but a rugged Casio I might. And I can see how the Op might while diving for utility and safety purposes.
 
Over. In my OPINION under looks freaking ridiculous. Like wearing a shirt backwards with the buttons on your back.
You obviously were not a fan of Kris Kross back in the day.

And the demo watches won't activate from sleep with motion. So I guess we wait until a reviewer video or launch day to see if the watch will wake from sleep while being worn underside.
 
Thanks. I also wanted to wear my watch under my wrist. Stil not enough of a reason to cancel.
Hmmm.... been wearing on the underside ever since I got it and never had problem with heart rate or movement before.
