I am surprised we cannot use the self-winding or normal wind-up mechanics for power generation to charge a battery to supplement solar, but I expect the experiments have already been done and it was either not cost effective or just did not give out enough power to be useful.
- JohnBooty 2y agoIt's been done and it works quite well from what I've read! I am not sure that Seiko still makes them, but you can still find some new ones for sale. Always wanted to get one of these since they're quite unique. https://www.seikowatches.com/us-en/customerservice/knowledge/kinetic-knowledge https://www.seikowatches.com/us-en/customerservice/knowledge... https://www.jomashop.com/seiko-kinetic-watch-ska791.html https://www.jomashop.com/seiko-kinetic-watch-ska791.html Unfortunately, Seiko's "Kinetic" movements don't seem to have ever been a big hit, so I don't know if it's something people actually wanted. Ultimately I think the "problem" is that regular solar watches work so damn well, and that most quartz buyers have no interest in "unique" movements. I mean, I do, but I'm the minority. And I still never bought one...
- lttlrck 2y agoI have had a Kinetic since 1999; a millennium birthday present to myself. It's a bit of an oddity. The lithium-ion power cell needs to be replaced every 5-10 years, and it's relatively expensive part. It has more mechanical complexity than a quartz plus the same maintenance. But it works really well. It's a hybrid. I love it despite this, it's unusual looking and the quirkiness makes it fun to talk about.
- JohnBooty 2y agoIs it easily user-replaceable? How expensive is it? I really appreciate your reply.
