If you search the archives there is a great write up on how to repair the clock if possible. In most cases a good cleaning and a point filing will get you working again. If I get a chance I'll see if I can dig up the write up on it. I've not done a write up on how to do the clock repair, but I have repaired plenty of them. This is a standard Borg movement and it is not very dependable.
As an alternative.... and what I have in my own car is the quartz converted clock. It is very dependable and accurate.

I like the 'original' style clock, but it is not that reliable. You might get about 5 trouble-free years with it before it balks, again.
The quartz conversion SHOULD be much more reliable. It will certainly be much more accurate and easier to reset. But, I have no personal experience with that particular kit. It looks similar to others I've seen. Nice that it has a DVD to provide instructions.
I did the quartz rebuild and it works great, the second hand sweeps instead of tics. I just saved the old clock if someone wants to put that back in someday. Also, like 7T1 vette says with the old points clock.....5 years and a re-do.
I put a replacement clock in my 72 when I rebuilt the dash. It lasted for 6 months then stopped. I think I am going to go with the quartz movement when I get around to replacing it again.
Actually, that GM clock design is very clever. But, the electrical contacts in the clock are not built for durability and reliability. It is also difficult to get the clock set properly; and when you disconnect, then reconnect the battery, you have to go through the resetting process all over again.
Neat, but troublesome...and not very reliable.
With the advent of electronic time pieces, that GM clock became obsolete and passe' (as a time keeper, anyway).

prefer the tick or increment movement of the second hand. I rebuilt my non working clock with the quartz conversion kit and the second hand now moves in a continuous sweep. It does work and if I did it over it again, I would consider the electric rebuilt option. For most C3ers, it probably does not make a difference.

Had a 65 clock run five years with just a point filing. Had a quartz movement installed by a PO work for 17 years before it quit. Did a quartz movement one time that turned out OK. The second one I tried didn't work and had to send it Wilcox to get straightened out. I like the nostalgia feel of the point clocks ticking but quartz is the way to go for accuracy and reliability.
