Seiko used to have a series of watches called Kinetic, where an oscillating weight charged a capacitor or battery. Weird that it's not mentioned in the article, as it seems to be just what's under discussion.
The issue is essentially solved for quartz, even Casio's electro-mechanic models can be powered by ambient light.
Edited, Seiko, not Citizen.
- inhumantsar 3y agoThe article is about hybrid electronic and mechanical timekeeping though, not energy source. While it has an analog display and a mechanical power source, the Kinetic's timekeeping is purely quartz. The Spring Drive has mechanical timekeeping which is automatically regulated by quartz.
