An extremely rare, probably unique Atmos (patent JL Reutter), the case forming a pyramid. Cabinet hard stone, at front cut chrome metal. Nicely aged white dial, signed Perpetual Atmos clock, Arabic numerals and blued steel skeleton hands. Movement: Calibre Perpetual Swiss mechanical mercury.
This clock was the property of a director of Jaeger, whom it had been given by his grandfather who actually was working for Jean Leon Reutter.
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 Léon Reutter. The clock is in a perfect condition.
