Inside the case, the clock instrument consists of a large white metal face which measure minutes. Two smaller dials on the inside of the larger minutes dial measure seconds and 24-hours. A pendulum consisting of two glass weights hangs from the clock mechanism that can be filled with liquid to increase their weight. A metal cord is attached to a small weight to a larger weight at the base of case. This mechanism powers the clock.
