24k Jeager-LeCoutre Atmos 540 Clock

The Jaeger-LeCoultre Atmos 540 table clock is a remarkable timepiece that defies conventional winding methods. Here are the technical details of this fascinating clock: Perpetual Motion: The Atmos clock operates without batteries, electricity, or manual winding. Since its inception in 1928, it has been powered solely by variations in ambient temperature. Its ingenious mechanism draws inspiration from Leonardo da Vinci’s concept of perpetual motion, although it doesn’t achieve true perpetual motion due to the laws of physics. Temperature-Driven Power: Inside a hermetically sealed capsule, a gaseous mixture expands when the temperature rises and contracts when it falls. Connected to the clock’s movement, this capsule acts like an accordion bellows, constantly winding the clock. A temperature fluctuation of just one degree Celsius between 15°C and 30°C provides approximately two days of operating autonomy. Slow Oscillation: The Atmos balance wheel oscillates at an incredibly slow rate—only twice per minute. To put this in perspective: - It beats 60 times less quickly than a traditional clock. - It’s 240 times slower than a wristwatch movement. - It’s a staggering 1,966,000 times slower than a quartz watch movement. - The energy transfer is so delicate that 60 million Atmos clocks combined would consume no more energy than a weak 15-watt electric light bulb. Longevity: The Atmos clock’s components are precise and dependable, resulting in virtually no wear. Theoretically, it can last up to 600 years! However, due to air pollution, regular checks and servicing are recommended. Its longevity makes it a true marvel of craftsmanship and technical performance. Design: The Atmos clock radiates serenity and pure design. Its glass cabinet showcases the intricate gear-trains, inviting you to explore its inner workings. The balance between technical excellence and elegant aesthetics defines this extraordinary timepiece.
