Question:

Is true that there's a wristwatch that can be charged with the hand's pulse?

I also heard that those kind of wristwatches are dangerous for the human body. Any answer will be appreciated.


Answers:

It's called an "auto-wind" or "self-wind" watch. It's got nothing to do with your pulse. It's about arm movement.
