i got this electric working tonight i have not tested it for accuracy yet. but when i put the dust cover on (i think its called the dust cover) the watch stops working. after several tries i left out the dust cover and its running just fine 10 min now with no stopping. why is that dust cover stopping the watch from working? should i have the dust cover on? is it bad for the watch? im a newbie please help. thanks robert

Can you post a picture of this alleged "dust cover"?
-or at least describe it?

...is propably bent so that it touches the balance wheel when you close the case. There should be a tiny gap between that cover and the balance wheel. If the cover is slightly bent it can come in contact with the balance wheel when you close the case/caseback. See if you can "bend it out" a little. The cover's "mission" ( I think... ) is to hold the battery in the right place/align the battery before you put on the backcase. Hope this helps - keep us updated!

...seems that the watch has a problem with the hairspring on the balance wheel. If there is oil/dirt on the hairspring it may cause it to run way too fast. The hairspring could also be damaged/bent. Are you able to look at the hairspring: do you see any damage ( twisted/bent )?
You are able to regulate the speed/timing of the watch, but if it runs as fast as you mention, simply regulate it wont be sufficient.

If you were able to post a pic then that would be great - there are several others here that know this better than me.

Perhaps what you are calling a "dust cover" is a metal shield that fits over the balance wheel coil and acts to protect that coil from external magnetic fields that could interfer with the watch's timekeeping.



If that is the case, then maybe that shield has, itself, become magnetized. If so, then that would account for it stopping the movement when it is installed. You might want to try degaussing the shield before installing it. If you do not have a commercial degausser then you can make one by wrapping an extension cord around a plastic cup and then plugging an appliance (like a toaster) into it that draws a lot of AC current. After you get that set up and there is AC current flowing in the extension cord, put just the shield in the cup and, after a few seconds, SLOWLY pull it out of the cup. This action should demagnetize it for you and, when installed in the watch's movement, it will no longer affect the timekeeping.

I asked the same question when I first started here, and didn't get a definitive answer. Since it obviously worked better without the cover, I left it out. Seems to work reasonably when worn, stops eventually (after a month or so) on my watch shelf. It's one of the more boring looking electrics, so it doesn't get much wrist time.

Sorry "Newbie"

I typed that with a helpful smile on my face but you can't 'see' that. I'm just not sure of what you're describing. Is it perhaps a spacer ring that is touching the balance wheel?

yes i looked carefully and i seen that the hair spring has a little kink in it. i tried to straighten it out but no good so i now need a new hair spring.or what ever its called. i also noticed that the battery was very warm. could this be from running to fast over night?
