An early Reutter gilt brass Atmos, no 321, 5 glasses, France circa 1930.
On these pictures the case has not been cleaned yet, but it is now in pristine condition.
Gilt brass case, transparency through the five glasses. Clock with an enameled dial, Roman numerals. On the back numbered 321.
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.
