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.
I don’t know about Seiko, but you can get the Citizen capacitors replaced for a fairly reasonable charge. My wife’s Eco-Drive needed a new capacitor after about 15 years. Mine is still going strong on its first after 25 years.
