The history of this Jaeger-LeCoultre Atmos
The invention of the atmospheric clock dates back to 1928 under the impetus of Neuchâtel engineer Jean-Léon Reutter. The concept pushed back the boundaries of physics by drawing its energy from the minute variations in temperature of the ambient air. A fluctuation of just 1 degree Celsius is enough to arm the mechanism and give this extraordinary creation 48 hours of autonomy. Reference Q5111202 continues this fascinating heritage. Nicknamed the Presidents' Clock, as it has been the official state gift of the Swiss Confederation since the 1950s, it embodies the pinnacle of Swiss mechanical engineering.
Case, calibre and bracelet of this Atmos
This feat takes its place within a majestic gilded solid brass cabinet measuring 225 mm high by 200 mm wide and 155 mm deep. 5 large panels of transparent mineral glass frame the levitating movement. The dial is distinguished by a white lacquered ring adorned with black Roman numerals flanked by pear-shaped blued steel hands. The centre reveals the mechanism and a rotating disc indicating the months. The lower part houses an elegant moon-phase display. As a table clock, it has no bracelet and rests on a tiered base fitted with micrometer screws and a spirit level for absolute flatness. The heart of the piece is the Manufacture Calibre 562, comprising 231 parts and 15 jewels. Its heavy annular balance oscillates at the slow frequency of 120 vibrations per hour and guarantees a theoretical power reserve of 7200 hours.
