I serviced this clock back in September, it just came back. It won’t run more than 5 minutes and goes out of beat on it’s own. To determine the problem, I made a small Sharpie mark on the anchor and it’s arbour. Then, looking at it at an angle, I could see that they were not moving together. I tightened it up by moving the sleeve containing the spring to compress it a little more, and that fixed the problem I’m not impressed with this system. Setting it manually is very difficult too. He said that he always stops the pendulum when he winds it once a week. Can using the auto-beat feature weekly overuse it to the point of failure? What do you think? Have you experience this? M.
