Timex Electric Battery Watch, runs only 3 to 5 seconds


Recommended Posts

    Fixing a Timex Electric (Dynabeat) Watch (battery) from the 1970's.....with battery will run only 3 to 5 seconds once shook. Battery compartment is clean & sanded contacts. I pulled crown / stem out & sets & moves hands (....when pushed in I can shake/rotate watch & will run for 3 to 5 seconds , ...... with stem/ crown pulled out , will not run....) I believe this is normal......The watch insides look very clean , no corrosion nor battery leakage....

     Can any members give me some information on what direction I should take on this problem? I believe this is a battery conectivity within watch movement.....are there any diagrams showing the inside of the movement & how the movement works.....battery & mechanical. Thank you in advance for your help.....Dan

Isn't said at all that is a contact issue. If the train and stepper motor aren't perfectly clean, as in old congealed oil or minuscule debris, the watch will stop, due to the very low torque that this type of motor has.

although you see the balance swing it could be just the result of you shaking it.  I'd say the balance coil and or the contact wire is the issue.

Thanks for your answere.....what can be done at this point & where are these located?....would soaking or appllying a bit of alchol or lighter fluid help ? Are there any diagrams which would show these areas ? Thank you again  Dan

Thank you also for your quick responce. If the answere is congealed oil or some small debris , what can be done......soaking or applying alchol or lighter fluid ?  Do you know of any diagrams for this particular watch style movement ?   Thank you for any suggestions   Dan

You have to be careful with soaking the movement since the balance has a lacquer coated coil on it.  So get a can of CRC QD Electric Cleaner.   One or two hits of the cleaner typically cleans things out. than dot the pivots with oil and add a fresh battery.  You jay also have to lube the ends of the balance ends. this is a bit more advanced of a task.  Do not demagnetize the movement.

Let see how this goes....

Thanks will try this electronic cleaner(...forgot coil is coated, no lighter fluid...) May be a few days to get this , but will try & let you know. Thank you....Stay safe under the circumstances...Dan

Did you get the contact problem sorted out?

I worked on 3 Timex Dynabeats in recent months. 2 were made in Germany and 1 in USA. They were completely different beasts.

I'm just discovering these little gems and loving there simplicity and cool styling.

Out of interest how do you get the balance in without it sticking to the magnet!

That is a tricky one. I remember removing the screws that hold down the magnet and sliding it out sideways. The magnet assembly plate sandwiches the coil of the balance wheel. Once the magnet is out, manipulating the balance is simple. But watch out for the contact spring.

No expert here,  but if contact wires do not properly connect-disconnect, it wont run. That is if the circutry and the coil are healthy.

so, I give the balance a nudge see if this activates the magnet, in which case it picks up and go.

If no induction in the coil, it is turning due to the shake you give it. 

I think I am just repeating what jersy has already said.:biggrin:

    • in general this shouldn't be any change. but in general questions like this it be nice to know the specifics of the watch in other words how was it performing before it was cased up and what is it doing now.
    • just as a reminder this watch is a Swatch group product. This will bring up a problem like spare parts and technical information. that I found some links to some information on when I talk about your watch and some of the technical and basically your watch is equivalent to 2834-2 for which I'm attaching the technical sheets. But equivalent does not mean exactly the same you want to do a search on the group for C07 as we discussed this watch before including the technical differences how it's supposed to be regulated and basically because it's watch group there is no parts availability. https://calibercorner.com/eta-caliber-c07-xxx/   https://www.chrono24.com/magazine/eta-movements-from-the-2824-2-to-the-powermatic-80-p_80840/ https://www.watchuseek.com/threads/h-10-movement-details.4636991/ eta CT_2834-2_FDE_481857_15.pdf
    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
