My dad has a Seiko watch (received as a gift) that doesn’t use any battery, but some kind of ingenious technology where all he has to do is shake the watch a couple of times to restore power every few weeks. It’ll last forever, but it was also probably expensive as hell. Does anyone know where I can get a watch that doesn’t need any replacement batteries for a good price?
