N0 196. A fine Art Deco Atmos clock, chrome  No 6981, by Jean Leon Reutter, circa 1930.

The case-transparency through the five faceted glass sides and skeletonised dial, Arabic numerals to indicate the hours. Visible red jewels. On the back the signature : Brevets J.L. Reutter. No 6981.
Working: The Atmos clock contains a drum with a U-shaped tube containing mercury and a gas. Due to temperature changes a thermique/ thermal current 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 and atmospheric pressure there is a continuous oscillation which causes the movement to roll permanently, we have a Pendule Perpétuelle. Original chrome case, dial and movement and in a perfect condition. The invention is the work of the French engineer Jean Leon Reutter. Very exclusive in this Art Deco design.
