    There is an old 2011 thread about this and I don't know how that story ended. I need a new motor for this clock -we've established that it's the motor that 's the problem. It is a Kugeluhr 220/240v, 50Hz; 3W. (The battery also says Netzbetriebenes elektriches Gerat! - I don't speak German but I think this is a warning).
    The clock was bought in Italy in 1991. Made in 'West Germany'.
    Can anyone help?

    Hi JoannaC,and wellcome to this message board.After Your description I have the idea that You have "the original thing",i.e. a Kugeluhr by Mattel,a famous producer of toys and models at that time.There were later imitations/repros and as far as I know a similar clock is still being produced in the far east.They all work differently.Yours is powered by a 220V 50Hz 1 RPM synchron motor,others had a quarz module to trigger the arm to lift one steel ball every minute.The black box containing the motor can be opened with care,please show pics of the motor,it should be replacable.Another solution is to buy an incomplete donor clock e.g. from evilbay;but if You do take care to buy the exact same model:they all look the same,but the power units are not interchangable. (at the moment I have two here,one original and one quarz type)
    Come back with additional pictures!
    Best regards
    Burkhard

    A bit of prying with a small screwdriver around the outside of the motor box cover should pop it off.

    could be the motor case is glued together,try with care or see if You can work out the glue out of the gap between the two covers that form the motor box.
    Good luck!In any case it is the example with the synchrone movement,should be replacable!

    These look similar, if not identical, to the Arrow rolling ball clock from the late 1970's. The Arrow's use a 117VAC, 60 cycle motor for which there no replacements anymore. I've had a few over the years and no longer run them as the motors last maybe a couple to five years before dieing. I've attempted repairs by cutting the cases lengthwise. Neither the internal motor nor the nylon gears can be found. NOS Arrows show up on eBay quite frequently for as low as $50. I'd stay away from used ones because of the motor problem. In any case they wouldn't work as a replacement for you. My favorites, and I have a couple, are the Harley Mayenshein Idle Tyme rolling ball clock from which Arrow purchased the rights and made them more 'affordable' by changing form wood construction to plastic and cheapening the motor. The Idle Tyme clocks use a 1 RPM time clock motor which can still be found, His son is building and selling limited editions of the original: http://www.idle-tyme.com/history.html

    Just a little history...

    Hi all. I have found someone who, hopefully, can mend it. Thanks for all your input - fingers crossed!

    today I had the oportunity to open my motor box which is slightly different from Yours:While both are held in place by two skrews through the box protruding in two posts mine has another two skrews only visible after taking of the box from its masts.These countersunk skrews hold together the two shels of the motor box and the motor itself in it.A few pics will show.HTH

    Look for an intermatic appliance timer in working condition, it uses the same motor, even the ones made now.
