I have a friend who's watch doesn't use batteries. It is powered by the movement of his hand. I would like to know the physics behind this. I read somewhere that the movement of the hand causes and oscillating weight, which causes the rotor to rotate. And that generates electricity. But that doesn't mean anything to me. Can anyone help me? I am not talking about self-winding watches. They are different.
