Similar to winders for automatic watches, the Seiko YT02A is a battery charger that charges Seiko Kinetic watches from an external power source.

Note that in normal use Seiko Kinetic Watches don't need an external winder, since they generally have a 6 month power reserve which is being replenished while you wear them, and they can be started up by shaking them from side to side if they do happen to run low. This winder is primarily used in repair and service facilities. We offer it as a handy gadget for the Seiko Kinetic collector who has more than a couple Seiko Kinetic watches and only two wrists!
