Working: The Atmos clock contains a drum with an U-shaped tube containing mercury and a gas. Due to temperature changes a thermic develops in the drum and causes the axle with the U-shaped tube to oscillate to and fro. Because of the continuous changes in temperature there is a continuous oscillation which causes the movement to roll permanently, we have a Pendule Perpétuelle. The invention was the work of the French engineer Jean Leon Reutter. The clock is original and in a perfect working condition. Very exclusive in this Art Deco design.
