    Bought a seiko coutura solar a few years back off ebay usa.

    From the off it stops unless left in very strong light.

    Sent it to seiko Ireland and they sent it back working .. but a few days later it stopped again.

    Should I bother with it or write it off ?

    Heres a pic ( the watch looks better than this pic! )

    Needs a capacitor or rechargable battery or whatever holds the charge.

    I presume you paid for that repair? If so, it comes with an implied warranty. Send it back to them, they should fix it free of charge.

    No it was free of charge though I had to pay for posting

    Most likely they stuck it under a light, it worked so they sent it back.

    Its possible that it's just empty and needs a really good charge.
    However more likely the battery will no longer hold a charge and needs replacing.

    Start off by pulling the crown (to stop the movement) and leave near a window that gets the sun. On a sill, or dresser/shelf etc. Try to face it south and angle up a tiny bit. Leave it for a week like that, just forget about it.

    That may not work, the battery is probably kaput. But it costs nothing to try and charge it first.

    Tried this already .. worked for a few days then stopped again.

    Just bin it ?

    If it cannot hold/take a charge then likely the battery needs replacing. It's something I would have expected the Seiko service centre to do or suggest.

    To do it yourself would cost maybe €10-25. The Seikos often use a dirt cheap (€5) button cell with little tabs welded on, so unless you're very handy you can't just buy the bare cell, you have to get it from Seiko at an inflated cost.

    If the watch has no value to you or it's not worth putting money into it, i'd give it away. I wouldn't bin something that can potentially be repaired, that's not particularly responsible.

    Find the caliber #. It will be on the caseback.

    From there you'd use google to find the battery type (you can also just open it up and have a look!), and then find a supplier.

    It's usually no more difficult than changing a regular battery. If you're unlucky it might be more involved but that's fairly rare with Seiko solars.

    i wonder could you put a standard 2 year battery in and hope the recharge circuitry doesnt affect it ?

    Many solar G-Shock owners have done this. They mostly use a CTL1616F which has same dimensions as CR1616. It's a dirty fix but works. The output of the solar panel is not really enough to do any harm to a primary cell.

    However your Seiko may use a tabbed battery. See the tabs which are spot-welded to it:

    So just putting an equivalent CR will not work. That's why I say you'd need to be handy. Some hobbyists are capable of peeling off the old tabs and welding them to an off-the-shelf MT920 or CR920.

    Find out what cell you need first, lets not get ahead of ourselves.
