It'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...
