This video will explain how to adjust the time on a Elgin Sigfried Haller Skeleton Anniversary Clock Germany c. 1986. The time adjustment is the same as any other standard 400 day Anniversary clock. The time adjustment is done by rotating the disk at the top of the pendulum either right or left depending on if the clock is slow or fast. The disk at the top of the pendulum has a Plus and a Minus symbol to show which direction to rotate the disk.
