I must pat myself on the back 😀🤗

When you posted originally of your dilemma I responded:


I need to read up on some of my books to fully understand. But here goes. I may be off a bit.

Most chronographs reset via a reset cam that rides with the minute timer gear. The resetting disengages the gear, the whole thing swings back and the cam stops against a “stop”. The minute counter hand is aligned with the cam. So it always resets to the same spot.

During timing, the minute timer gear is engaged. A minute goes by, gears rotate, stop, wait for another minute. If you can imagine most of those teeth being fine, but one or two being worn or missing, when the time gets far enough to engage those teeth, the gear would jump a couple degrees pasted where it should until the next good teeth engage.

I’m stuck at home. I need some brain teaser to occupy my time. Thank you.




I think your description matches mine. Off to horological Acadia go!!👨‍🔧
