Wristwatch Pillow

A good wake-up wristwatch that violently vibrates?

I’m trying to find a decent wristwatch that violently vibrates. I want to use it as an alarm clock for waking up in the morning. I can’t use a very loud alarm clock, because that would wake up people around my dorm area. I’ve also thought about using one of those vibrating pads, but I’m the kind of person who throws around pillows. Does anyone know of a good vibrating watch for waking up?

Yes it’s called female.
