KEY FACTS:
1. A story of design: more than nine decades of creativity and craftsmanship told in 4 chapters
2. A tribute to mechanical ingenuity: a revolutionary ‘perpetual motion’ horological concept, where infinitesimal variations in the ambient air temperature provide 48 hours of autonomy
3. An immersive experience: bringing together a collection of 19 different Atmos clocks and supported by archival materials, technical drawings as well as watchmaking demonstrations
During Milan Design Week this April, Jaeger-LeCoultre invites the public to discover ‘Living on Air’, an immersive exhibition that tells the remarkable story of the Atmos clock. Invented in 1928, with a unique mechanism that is driven by tiny changes in air temperature, the Atmos clock is a mechanical marvel and objet d’art in equal measure.
‘Living on Air’ is open to the public free of charge and will run from 8–13 April 2025 at Villa Mozart in the historic centre of Milan. During the exhibition, Jaeger-LeCoultre will unveil a new limited-edition Atmos clock that reflects the contemporary design values of Milan Design Week.
AN EXHIBITION TELLING THE STORY OF THE ATMOS CLOCK IN FOUR CHAPTERS
Founded in the Vallée de Joux in 1833, Jaeger-LeCoultre has been known for more than 100 years as the Watchmaker of Watchmakers™. As the guardian of the Atmos clock’s remarkable technology for more than 90 years, Jaeger-LeCoultre has continually worked on technical improvements and new developments and, since the 1970s, has invited a series of leading designers and masters of the artistic crafts to reinterpret this mechanical prodigy.
Bringing together an unprecedented collection of 19 different Atmos clocks spanning more than nine decades and supported by archival materials and technical drawings, as well as a watchmaker demonstrating how the mechanism works, ‘Living on Air’ tells the story of this extraordinary object in four chapters.
THE GENESIS: The (Seemingly) Impossible Dream traces mankind’s fascination with the idea of perpetual motion machines, with records dating back at least to first-century BC Alexandria, and reveals how, in 1928, Jean-Léon Reutter, a Swiss radiological engineer succeeded in incorporating the principle of perpetual motion into a prototype clock – apparently defying the laws of physics.
On buying an early example of the clock Jacques-David LeCoultre realised that the mechanism required exceptional watchmaking skill to make it viable and invited Reutter to join forces with the LeCoultre & Cie Manufacture to refine it for commercial production.
In the second chapter, THE MECHANISM: Inside the Atmos, visitors will discover how the Atmos clock comes closer to perpetual operation than any other mechanism yet created. The energy that drives the clock is supplied by normal fluctuations in air temperature. In live demonstrations, visitors can see how thermal energy is transformed into mechanical energy to power the movement.
THE DESIGN: Atmos as an Objet d’Art celebrates the decorative crafts that elevate Atmos clocks into works of art, as well as highlighting how Jaeger-LeCoultre’s collaborations with leading contemporary designers have transformed the Atmos. Among the exhibits is a series of models created in collaboration with the renowned designer Marc Newson and exceptional examples of Atmos cabinets created by masters of wood marquetry and straw marquetry.
Because the Atmos system produces only a small amount of energy, its movement must consume as little as possible. In the chapter THE COMPLICATION: Beyond Timekeeping, visitors will discover how Jaeger-LeCoultre’s engineers solved the problem of adding functions to the clock without increasing energy consumption.
They discovered that the ideal complications were those based on the long, slow cycles of the astronomical phenomena that lie at the origin of time measurement – such as the moon phases and seasons. Among the exhibits is the most complicated Atmos yet made, the Atmos Tellurium.
More than nine decades after its invention the Atmos clock remains a unique and emotionally resonant keeper of time – a splendid homage to design and technical virtuosity that captivates with the beauty of its form, the serene movement of its balance wheel and the mystery of its workings.
‘Living on Air’ will run from 8–13 April 2025 at Villa Mozart (First Floor), via Mozart 9, Milan and is open from 11.00 to 19.00 (except on Wednesday 9, from 11.00 to 18.00). Visitors may register online in advance at bit.ly/Atmos-LivingOnAir or on arrival at the exhibition.
HOMO FABER FELLOWSHIP EXHIBITION
Concurrently with ‘Living on Air’, Jaeger-LeCoultre is participating in a second event during the Milan Design Week, as the principal supporting partner of Homo Faber Fellowship. ‘Today’s Masters Meet Tomorrow’s Talents’, presented by the Michelangelo Foundation, is being held at the Casa degli Artisti in Brera. The exhibition features co-created objects designed and handcrafted by 23 duos who were part of the second edition of Homo Faber Fellowship.
