This morning my Seiko Kinetic SKA427 stopped. I shook it a few times and the minute hand remained motionless. I shook it again. Nothing.
Panic set in. Was I going to have to take my Seiko, purchased only 6 weeks ago, in for repair?
I shook it again for about a minute and the minute hand started ticking. I think I'll wear it every day for a while to give it a charge.
My guess is that it takes longer for a kinetic Seiko to "communicate" with the rechargeable battery that it's getting charge and may take a good minute of shaking before you see the second hand ticking. In contrast, my Seiko automatics, like the Black Monster, start ticking within a few seconds.
