But they still use energy.

Yes, I have one. It's a matter of reducing the energy required. A self winding watch uses wrist motion which is excess energy like a solar watch that used the sun or light. The Atmos uses temperature change to power a chemical reaction to wind the mainspring. A 2 degree change a day in enough to keep it going.

Yes but they all use energy and use and loose it.

Well, yea that be the whole idea that there's no free lunch and no Perpetual Motion Machine.
