Jaeger-LeCoultre used Milan Design Week 2026 to unveil five exceptional clocks, placing the Atmos and the Memovox Travel Clock at the centre of a broader conversation about perpetual time, design and decorative craft.
Staged at Villa Mozart from 21 to 26 April, The Perpetual Timekeeper exhibition brought together 53 archive timekeeping objects and 32 Atmos clocks spanning nine decades.
Villa Mozart framed the Atmos as an object of design
The exhibition was organised across six chapters and gave equal weight to mechanics, material experimentation and the long-running collaboration between Jaeger-LeCoultre and Australian industrial designer Marc Newson.
Newson’s furniture appeared alongside three of the five new timekeepers, underlining how far the Manufacture is willing to push the clock beyond its traditional cabinet form.
The five debuts were the Atmos Designer Calibre 568 by Marc Newson, the Atmos Hybris Artistica Tellurium by Marc Newson, the Memovox Travel Clock by Marc Newson, the Atmos Régulateur Enamel Colibris and the Atmos Régulateur Wood.
Marc Newson’s Atmos Designer Calibre 568 turns crystal into architecture
The Atmos Designer Calibre 568 is built around a Baccarat crystal cabinet that took nearly four years to develop, with a rounded square profile that suggests a slowly melting block of ice.
The hand-formed crystal is as thin as 13 mm in places, yet it holds a complex astronomical display with a remarkable sense of lightness.
The dial is reduced to black-tinted sapphire crystal with white Arabic numerals, a minute track, a French month ring, sunrise and sunset indications, an Equation of Time display and a moon phase accurate to one day in 4,087 years.
Its most intriguing technical detail is location-specific calibration, with three versions produced for latitudes of 30, 40 and 50 degrees so the astronomical indications correspond meaningfully to where the clock is used.
Production is planned at 50 pieces per year across the three variants, with references Q516511J, Q516512J and Q516513J.
The Atmos Hybris Artistica Tellurium builds a universe in glass
The Atmos Hybris Artistica Tellurium is the most theatrical of the new releases, placing Calibre 590 inside a glass sphere engraved with the 64 constellations visible in the Northern Hemisphere.
Its surface is set with 539 cabochon-cut sapphires totalling 32 carats, creating the impression that the principal stars are suspended directly in the glass.
Inside, a translucent blue sapphire disc carries zodiac symbols, while a polished 18K pink gold sunburst indicates the current sign.
The Earth rotates once every 24 hours, the Moon completes its orbit in a synodic month of 29 days, 12 hours, 44 minutes and 2 seconds, and the moon phase will deviate by only one day after 5,770 years.
The piece also includes a laser-engraved lunar plate, meteorite inlay on the Earth-Moon ring, a hand-painted miniature Earth and a blue calf-leather plinth crafted by Serapian with the Milanese workshop’s Mosaico weaving technique.
Measuring 270 x 285 mm, the Atmos Hybris Artistica Tellurium is limited to three pieces under reference Q5765310.
The Memovox Travel Clock gives the alarm clock serious mechanics
The Memovox Travel Clock is the most portable and functionally direct of the Milan launches, but it is far from simple.
Its 69 mm titanium case is 18 mm thick and uses a spherical form with an integrated folding stand for bedside or desk use.
Inside is the new manually wound Calibre 256, an in-house movement with two large barrels for timekeeping, a third barrel dedicated to the alarm and a 12-day power reserve.
That reserve is shown through 12 narrow apertures around the numerals, with orange indicators turning blue as each day passes through a patented system using two intertwined helicoidal rings.
The alarm continues the Memovox line that began in 1950, while Newson’s travel concept extends to a tan open-pore cowhide kit made by Schedoni, including a pouch, three-watch travel pack, magnifying glass, strap tools, screwdriver and display stand.
The Memovox Travel Clock will be produced in 100 numbered pieces per year as reference Q614T020.
Grand Feu hummingbirds and the return of rare decorative crafts
The Atmos Régulateur Enamel Colibris is a showcase for Jaeger-LeCoultre’s Métiers Rares atelier, with miniature-painted Grand Feu enamel panels depicting hummingbirds among cherry blossoms and hydrangeas on a deep green ground.
The dial and two large side panels required 45 separate firings at 800°C or higher, with 15 enamel layers on each surface.
Gold-leaf paillonné markers add another traditional technique, while the full enamelling work took 230 hours to complete.
Calibre 582 gives the clock a regulator-style layout with separated hours and minutes, a 24-hour indication, month display and a perpetual moon phase accurate to one day in 3,821 years.
The glass cabinet measures 468 mm x 183 mm x 255 mm, with the movement suspended between the enamelled panels and finished with PVD-coated base elements and rhodium-plated details.
The Atmos Régulateur Enamel Colibris is limited to three pieces as reference Q5604305, while the Atmos Régulateur Wood completes the five-clock presentation with a further emphasis on the decorative possibilities of the Atmos format.
Pricing has not been announced for these creations, which is unsurprising given the scale of handwork, limited production and bespoke technical content involved.
For collectors, the Milan launches show Jaeger-LeCoultre treating the clock not as a historical side category, but as one of its most fertile territories for experimental mechanics, astronomical displays and contemporary design.
