Default 71 clock spring repair question

My list of “while I’m at it’s” is growing by leaps and bounds for my seat foam replacement, but so it goes...

have read several threads about clock repair, but I seem to have found a unique one. Upon opening the case, the spring that drives the mechanism was disconnected. Any chance someone could give me a reference pic or link to tell where the unattached end should go? I think I have an idea, but would love to fix it once and done.

If you are speaking of the long coiled spring that is stretched when the solenoid fires, you just need to determine WHY it became disconnected and restore it. If the end-loop on one end failed and broke off, you might be able to take the next 1 or 2 coils and bend them 90* to form a new end connection, then reconnect it.

If you are speaking about the balance wheel spring, take it to a jeweler who does watch repair. They can assess the damage and possibly fix it. Otherwise, it's time for a new QUARTZ movement.

It is indeed the long coiled spring you mentioned first. My pic shows it as I found it disconnected. The loose end appeared to originally have a loop that became stretched out and likely pulled free. I’m able to use some surgical instruments and bend a makeshift loop back into the end, but I’m not sure where to attach it now.

Well, you did say, you wanted it fixed once and Done.
I have known more than one who have repaired these early clocks. Only to go back in later and put in a quartz convertion kit.
just saying.

After all the heroics to get the dash out, one and done is definitely the preference!

Buy the quartz clock or the replacement quartz movement, if you can locate one. Never screw with it again!!!

The stock clock was a clever and cool design. But it's weak spot was "reliability".....

Now, if someone would develop a quartz replacement clock with a needle which pulsed every 1/2 second (like the stock clock) and with a little sound module that mimicked the re-winding sound every 2 minutes , even the NCRS folks would be happy.
