Seiko Kinetic SKA623 Head Only
I bought this watch a while back for the bracelet. I have since sold that, but not sure what to do with the head. So, maybe you could use it? The watch runs when you shake it up. I am not sure how much is in the capacitor. If you find it doesn't run very long, we could do a refund. I just want it to go to someone who could use it.
