No alarm on Apple Watch from Sleep schedule

Hi,

I've set a Sleep schedule on the iPhone to wake me at 6:30am on weekdays. The alarm at 6:30am only goes off on the iPhone, not on the Watch, while I would like that to be the other way round. I keep the Watch on my nightstand, charging. The iPhone is in another room.

I can't find a way to activate the alarm on the Watch. Any suggestions how to fix this?
