    Question How to make a clock to run backward?

    I recently got a battery operated clock donated to me for halloween. I would like to make the clock run backward. Is there an easy way to do this? Looking at the back of the clock it seems to be the standard clock works in a black case and a place for a 2AA battery. Thanks for any help.

    Since it's battery operated, you may be able to just put the batteries in backward. D.C. motors generally don't care which direction they run. There may be something in the gearing that keeps it from turning backwards, but I doubt it'd hurt to try.

    Most likely, it's a quartz movement type clock mechanism (easy to tell if it has a second hand, it will move and stop every second -vs.- a Swiss movement which smoothly sweeps w/o a momentary pause). A quartz movement will have a permanent magnet inside of a electromagnetic core. To reverse this type, you simply pull the electromagnet out, turn it over, and reinsert the electromagnet. It's a simple hack that only takes about 5-10 minutes with most clocks.

    I already had tried that before I posted but thanks for the response.

    I tried this but do to the way the case is made it was not possible. I am going to run to Michael's and see of I can buy a replacement that will be easier to modify. Thanks for the information it was what I was looking for.
