The following three lots represent fine examples of Jaeger-LeCoultre's celebrated "Atmos" clocks, originally invented by Jean-Léon Reutter (1899-1971), an engineer from Neuchâtel. His system of a clock wound by atmospheric fluctuations was patended in 1928.
The patent was purchased by Jaeger-LeCoultre in 1935 and since then, the company has been producing these highly popular timepieces in different styles.
