There’s a seiko kinetic watch in my collection that charges a capacitor with a rotor, and turns off the hand movement when it senses no activity for a period of time (I don’t remember how long). Eventually, the capacitor went bad and the watch doesn’t hold a charge anymore. It probably lasted me 12 years before this happened. It still holds a place of honor in my watch box, but I haven’t been able to wear it for probably 6 years.
