The clock in R66 did the same thing. Removed it and cleaned and oiled every thing, ran great on the bench on it's back. Put it back in the car and it would run a point cycle again and stop. Out 3 times and finally figured out the shafts on the gears had worn the holes in the brass plates to an oblong hole and the gears were binding when the lever to trip the points put pressure on the gears.
Set it for 5:00 and disconnected the 12v supply to it. I can stop for a cocktail or beer anytime I want.
In my 66 Sting Ray the clock runs for one minute then quits again. What do I need to do to get if going
Depends on what you want. A typical failure mode is the contact points are corroded/pitted and aren't completing the electrical circuit to the coil, which when energized is what winds the main spring. Removing the clock, opening the case and dressing up the points isn't that hard to do.
If that's the problem and you address it your clock will run but likely won't keep accurate time. If having a clock that keeps accurate time using the original "works" is important, you'll have to find someone who can restore it. For mine, I don't care about how accurate it is - I wanted to keep the original movement. You can also add a switch to the circuit and only run the clock when you want so that the "wear" is reduced.
if you don't care about the original "works", there are quartz conversion kits available that will keep accurate time, aren't terribly difficult to do and aren't very expensive. However these conversions have the second hand going at a constant sweep, instead of the "ticking" of the original movement. Many of the vendors carry those conversion kits.
You can can also search this forum for more opinions/information on this topic.
If you're up to disassembling the clock you can clean those points and maybe take care of it. typical event when that's the problem, if you pull out set **** and release it quickly so it snaps it will jar the points and then it'll rewind and run for another minute, then stop and continue that over and over

65GGvert,
That was the path that I took....Ended up stalling again after a few minutes of operation..I ended up sending my clock to Instrument Services for a quartz conversion. Perfect ever since......

All the best and good luck, OP.

I put quartz in both my 60 and 65. I feel safer without the electric relay having the chance to bind up on the stock ones and run the battery down or melt some wires.

Tricks or tips on removing the clock. I’m a rookie
Remove the glove box door and liner, work from the side. The clock is held by two ball studs on the back that have snap on spring clips to hold the clock in the dash center fiberglass.
The clock then pulls out over the console.

I installed the quartz clock from Corvette Central, it does the tic tic movement, not the steady sweep like some conversions.
That’s what I did and bagged and tagged the original.
Can’t tell the difference in looks or hand movement. I don’t know if it actually makes the “ticking” sound. If it does, it’s pretty quiet. My elderly ears can’t hear it.
Thanks for the replies. I’ll take out and send off for repair.
You probably made the right decision. Fixing things is challenging and rewarding but the clock is NOT easily removed or reinstalled especially replacing the retaining clips. All I can remember is close quarters work space, sore neck and cut hands. Decided to send mine to Clock Works to avoid reinstalling and removal again. Spend your time fixing something else.
I didn't have that much trouble getting the clock out of my 67. I cleaned the contacts and applied a little 3 in 1 oil on the gears and the darn thing starting working. The picture shows the back of the clock. It shows the one ball (don't know what you call it) without the clip and the other with the clip. You just push the top of the clip in and slide it up. I took the radio out while I was in there and sent it out for repair.
Another vote for the new quartz replacement clocks. I put one in my 65 and it is great. It ticks rather than sweeps and it has not lost a minute in three years and it was cheaper than the cost to restore my old unit. I still have the original in a bag, but I will never go back. Someone recently asked how to tell if a C2 clock is a quartz or original. The reply was to look at the time. If it is correct, it is a quartz.

Doc - same experience here. Bought/installed the “tick tock” quartz clock and bagged the original. Always shows the correct time and has a very tiny parasitic draw.

Yup - and you can do this while sitting in the passenger seat the whole time...
