Jaeger-LeCoultre has released the Atmos Infinite “Halo”, a contemporary reinterpretation of the maison’s legendary perpetual clock. First introduced in 1928, the Atmos runs almost indefinitely, powered not by winding or batteries, but by subtle changes in air temperature. The new Atmos Infinite takes this near-magical horological feat and cloaks it in a strikingly modern aesthetic.

The cylindrical glass cabinet provides an unobstructed 360-degree view of the intricate Calibre 570, its balance wheel, membrane, and chain seemingly suspended in motion. A white lacquered dial, composed of two concentric circles with polished baton indexes, enhances depth while maintaining crisp readability. Complemented by fine watchmaking finishes that catch and reflect light, the Atmos Infinite becomes both a timekeeper and a kinetic sculpture.

Jaeger-LeCoultre’s innovation goes beyond beauty. The clock’s hermetically sealed, gas-filled capsule allows it to harvest energy from the slightest fluctuation in room temperature. A one-degree shift is sufficient to wind the mainspring, providing a two-day power reserve and enabling a nearly perpetual running time of 7,200 hours. Water and power connections are unnecessary—nature itself sustains it

The limited-edition Jaeger-LeCoultre Atmos Infinite “Halo,” priced at $20,000, is available in just 100 pieces worldwide. It is a collector’s dream that bridges art, science, and heritage, reinterpreting the Art Deco glass-box aesthetic for the modern age. Elegant, sustainable, and endlessly fascinating, the Atmos Infinite proves that the pursuit of horological innovation is far from over.
