Nice model nickel case, transparency through the four glasses. Clock with Art Deco Arabic numerals on silvered dial. On the back signed ‘Brevet J.L. Reutter, S.G.D.G.’ and numbered 3103. Absolute pristine condition.
Working: The Atmos clock contains a drum with a U-shaped tube containing mercury and a gas. Due to temperature changes a thermics 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 Léon Reutter. The clock is in a perfect condition.
Very exclusive Art Deco model.
