Notes

The Atmos clock was invented by Neuchâtel engineer Jean- Léon Reutter (1899-1971). In 1928 he succeeded in producing a clock that was wound by atmospheric fluctuations. Reutter?s patent was licensed to a French company until 1935. It was then acquired by Jaeger-LeCoultre. By 1979 there were half a million such clocks; they had become popular and were presented to heads of state during official visits to Switzerland
