JG3056-2

This clock two-pin disc clock, the whole appearance is like an ancient water wheel, walking part of no spring, with the ball gravity as the power source, the ball every minute out of the water wheel, and through the water tank into the left bucket, and then through the mechanical transmission of the wooden shell into the top of the water wheel, so that the clock can run again and again, the ball movement every three days once string.

The clock is a rare artifact from the 17th century in the United States.
