My wife's uncle gave me this as he is no longer using it at 90 years old馃槼.
It know very little about Seiko watches so would be grateful knowing about its age and any info folks can share ?

Is there a serial number on the back? If so, the first digit will give you the year and the second the month of production.

On mine it shows power reserve while running. 30 "seconds" being full charge.

have fun

These are from early 90s and movement of your arm generates power stored in a lithium capacitor. They can last 5-10 years before needing replacement of capacitor.

Show us photo of back can give more info including reference number and date.

Shake it back and forth for about 2 minutes then press the pusher at 2:00. The charge indicator is how far the seconds hand moves.

They are great if you wear them regularly. The technology was superceeded by solar cells in early 2000s so they are a bit of Seiko historic niche.

If there is no indictator of life after 2-3 min back and forth shaking ( like dealing cards) then you will likely need new capacitor.
They are available on EB about $50 and are specific for reference. They are a little fussy to install but doable if you鈥檙e handy changing batteries.
If you get it running wear it for 4 or 5 days and see if you get it to full charge. Then it鈥檚 good for months.
I just changed capacitor on this one for a friend who got it new as gift and let it sit unworn in box for 10 years now it鈥檚 running like new.

I have one of these kinetics also. The only issue I have is that it runs down fairly fast if not worn daily. Motion actually generates electricity to charge the capacitor that runs the watch. A standard watch winder won't charge it. Seiko made a special inductive charger but they're quite expensive on Ebay if you can find one. According to online lore, certain toothbrush chargers would impart a charge when placed on the watch but I didn't have much luck with that. It's a whole rabbit hole you can go down if you're interested.

Thanks for this - hilarious about the tooth brush charger- that is thinking outside of the box!

Does your watch run after some shaking?

Yes it does run but the button at 2 pm does nothing when depressed , so I suspect the capacitor needs replacing?
Thanks
