J.L. REUTTER | ATMOS PENDULE PERPETUELLE GILT-BRASS TABLE CLOCK WITH GLASS COVER CIRCA 1935

Invented by Jean-Léon Reutter in 1928, the Atmos clock is an exceptional fusion of technical knowledge and utility, it requires no mechanical or electrical intervention to keep time, but instead it uses the slightest changes in atmosphere to power its perpetual motion. The invention continues to be a success story and the clocks are still produced by Jaeger-LeCoultre in the Valée de Joux. 

What makes this particular lot exciting is that it is an early example from the 1930s signed 'Brevets J.L. Reutter - S.G.D.G'.
