OVERVIEW
UNIQUENESS: THE PERPETUAL CLOCK SHAPED BY MÉTIERS RARES™
DESIGN
TIME, TURNED TO ART
The Atmos Régulateur Enamel Colibris unites mechanical precision with decorative mastery. Set within a transparent glass cabinet, its Calibre 582 regulator movement is framed by two Grand Feu enamel panels. Hummingbirds and blossoms unfold in a continuous composition even across the solid silver dial, creating an immersive panorama.
REGULATOR DISPLAY ROOTED IN PRECISION
The Atmos Régulateur Enamel Colibris adopts the regulator layout traditionally used in scientific reference clocks. By separating hours and minutes, it establishes a clear reading hierarchy that enhances precision and legibility. With the minute indication placed at the centre of attention, the display reflects a longstanding horological pursuit of exact time measurement.
IMMERSIVE ARTISTIC PANORAMA
Set within a transparent cabinet, the composition unfolds in a seamless flow from one enamel panel, across the silver dial, to the other side. Hummingbirds and blossoms surround the mechanism in a continuous landscape. Grand Feu enamel and subtle paillonné details enrich the scene, uniting artistic craftsmanship with perpetual motion.
CRAFTSMANSHIP
230 HOURS OF MÉTIERS RARES™
The Atmos Régulateur Enamel Colibris showcases the exceptional craftsmanship cultivated within the Maison’s Métiers Rares™ atelier. Grand Feu enamel lends depth and luminosity to the composition, while gold leaf paillonné details introduce subtle points of light that animate the surface. Together, these time-honoured techniques elevate the clock into a true work of art, where decorative mastery enhances the precision of the mechanism it frames.
A SCENE IN FIFTEEN ENAMEL LAYERS
The enamel panels of the Atmos Régulateur Enamel Colibris measure 196 mm by 105.2 mm, presenting significant technical challenges. Executed on a steel base for greater resistance, the surface undergoes 45 successive firings at temperatures exceeding 800°C. A counter-enamel layer is first applied to stabilise tension, followed by dry enamelling to achieve uniform depth of colour. Each firing demands perfect cooling and flattening, as any imperfection would compromise the entire composition.
AN ILLUMINATION OF TIME IN GOLD
The hour and minute markers are created using the paillonné technique, which involves cutting fragments of 24K (999/1000) gold leaf and positioning them with absolute precision before sealing them beneath layers of translucent enamel. Each element must be fired repeatedly to fuse seamlessly with the surface. This meticulous process requires exceptional control, ensuring that the gold retains its brilliance while remaining fully integrated within the enamel structure.
CALIBRE
THE CLOCK LIVING ON AIR
The Atmos mechanism is powered by tiny variations in ambient temperature, using no winding and no external energy source. A hermetically sealed gas capsule expands and contracts, transmitting this motion to wind the mainspring with extreme efficiency. A change of just 1°C can provide about 48 hours of running time. Its consumption is so low that 60 million Atmos clocks would use the same energy as a single 15-watt light bulb.
PERPETUAL REGULATOR MOVEMENT CALIBRE 582
The Jaeger-LeCoultre Calibre 582 is entirely conceived and produced in the Atmos atelier. Its regulator display separates hours and minutes for exceptional legibility, a layout historically used in precision reference clocks. The architecture is organised in concentric rings, with a suspended 24-hour disc stabilised by three open-worked guide rollers in a pyramid layout. The moon phase indication completes the display and remains accurate to one day in 3,821 years.
