what to check to have regulator centered

movement

movement 2

case back

case inside

Using a toothpick, rotate the teeth of the star wheel clockwise and the regulator arm will adjust back to center.

Someone has possibly pushed the regulator to "slow" as it probably was running "fast" and needs a COA [clean/oil/adjust]. A watch usually runs fast when it is getting low on oil. That's usually...

David may have answered your question, I was wondering if that's what you meant or not. Its not a good idea to run a watch if its in need of a cleaning.

Buster's advice is very important. I do not recommend you run it for any extended period unless you know the service history includes a rece3nt cleaning.

David, Buster, thank you for responding. Actually the watch has been in for a clean/oil, I'm not sure about the adjust though. It has been about 3 weeks since the service and it has not lost or gained a minute at all.

To be honest it simply did not register that the regulator was off center that much until the other day. I had read since that a fix may involve a hairspring adjustment or weight adjustments.

Rick, that adjustment means little to nothing on the long run. Usually the micro-adjust helps "bring in" the last couple of position errors if they are affected by gravity on the hairspring. (Yes that IS an error cause.)

Thank you David, greatly appreciated.

You may have noticed I had two posts virtually the same. My granddaughters were helping, did not know what happened to the first post so posted again.

Dr. Irvine, once again, thank you
