As the spring it set it then starts ticking down - letting the spring contract until the contact points touch once again, forcing them open as far as possible and stretching the spring back out as far as possible. Then lather, rinse, repeat. If the car voltage runs down toward a dead battery it can get to where it doesn't have enough energy to force the points back open again and the points can burn some or fuse together. Clock won't work again until some corrective action is taken.

Here's a video I made with the clock hooked up and running outside of the car. You can see and hear the tic-toc sounds it makes. Quartz movements are essentially silent and the clock second hand will sweep smoothly around instead of the tic-toc movement of the second hand in an original. You can probably see the second hand stops for a split-second every second, unlike quartz clocks.

Also, when the contact points touch it makes a very distinct sound. You can hear it reset and see the contact points on top move back fully open again.
