Citizen, Seiko, Casio all seem to offer a wide range of solar powered watches now. I wonder what the ranges are for energy collected by watches for various thermal, kinetic, and solar methods? I've had a Citizen EcoDrive (solar) for over a decade now.. it just keeps going.. Edit: I see now Citizen also started (1999) and stopped making thermal powered watches... https://en.wikipedia.org/wiki/Eco-Drive https://en.wikipedia.org/wiki/Eco-Drive
