Notes

The ?Atmos du Millénaire Atlantis? This mechanical clock is a technical masterpiece that will run until the year 3000 without rewinding. According to Jaeger Le Coultre only 50 will be produced annually. Through the concept of a quasi-perpetual movement, the clock runs on subtle changes in barometric pressure and temperature, a fluctuation of only one degree is sufficient for two days? operation. The Atmos clock was invented by Neuchâtel engineer Jean-Léon Reutter (1899-1971). From his youth, he was preoccupied by the idea of industrially producing a clock that could be wound by atmospheric fluctuations, and in 1928 he succeeded. Reutter?s patent was first licensed to a French company who exploited it until 1935. Subsequently, it was purchased by Jaeger LeCoultre. After difficult early years, by 1979 there were half a million such clocks which quickly became popular and prestigious gifts for the important heads of states during their visits to Switzerland.
