Timex Dynabeat

[markr]

I have two Dynabeats that both tick when batteries are installed but hands are not moving. Is there an easy fix for this or do they go in the pile of watches to be taken apart and cleaned?

JerseyMo our resident Timex electric expert recommends a good squirt of contact cleaner. This is usually to get them going. But this sounds like a cannon pinion problem. I think it's got something to do with a spring clip that locks in the drive from the train to the hands. So needs to cone apart. If I rememberthat clip is tricky to fit.

Hi I believe the dynabeat was based on the model 40 with the 41 having the calendar work. I have attached the tech sheets for both, the 40 being the base movement my be of some use should you decide to work on them.

Thanks W.W.  There is one of each so both will come in handy.  I probably have another 6 non workers in a to do box somewhere that I'll probably get to 20 years from now.

do the hands move in set position?  Does the seconds hand move when the movement is running? if no to both that yeah they have to come apart and I'd be surprised if just a cleaning gets them going.

Thanks Mo.  I can set the hands but hands not moving when running.  I think I'll throw them in the parts box.

Try removing the shunt bridge and see if the pallet fork is moving. You can also try removing the hands and dial and loosen the balance screw a little then dunk the whole movement in lighter fluid.
