Reading Time: 6 minutes

There are moments in watchmaking when a Maison stops speaking about time and starts speaking with it. Jaeger-LeCoultre did exactly that in April 2026 in Milan, unveiling five exceptional new clocks that push the boundaries of both technical mastery and artistic expression.

The Perpetual Timekeeper Exhibition

From 21 to 26 April 2026, Jaeger-LeCoultre opened the doors of Villa Mozart in the historic centre of Milan to present The Perpetual Timekeeper, an immersive, free-to-attend exhibition organised around six chapters and spread across a curated selection of 53 archive timekeeping objects and 32 Atmos clocks spanning nine decades. The exhibition celebrated a long-standing creative partnership with Australian industrial designer Marc Newson, who first collaborated with the Manufacture in 2008, and whose signature furniture pieces featured alongside the horological unveilings. Five new clocks anchored the show: three Newson designs and two Atmos pieces dedicated to the Maison’s most treasured decorative crafts.

Atmos Designer Calibre 568 by Marc Newson

Newson strips the dial of Calibre 568 down to its purest expression. Arabic numerals print in white on a black-tinted sapphire crystal disc, encircled by a minute track and an inner ring marking the months in French. Beyond that ring, a concentric sapphire crystal disc carries the sunrise and sunset indications, each marked by a small arrow at the disc edge, whilst the Equation of Time appears as an ellipse surrounding the hand arbour, shifting to display the correct +/- minutes on a scale behind it. At 6 o’clock, a smoothly finished disc handles the moon phase, with a deviation of only one day every 4,087 years.

Calibre 568 oscillates twice per 60 seconds and carries displays for hours, minutes, month, sunrise/sunset, Equation of Time, and moon phase. The latitude-specific calibration is the headline technical achievement: Jaeger-LeCoultre produces each of the three versions of this clock to correspond to latitudes 30°, 40°, and 50° respectively, making the astronomical indications genuinely site-specific. The attachment of the movement to the cabinet uses four symmetrically placed points rather than the traditional three, adding both structural precision and visual balance when viewed from the rear.

Newson turned to Baccarat, the French crystal manufacturer founded in 1764, for the cabinet. The mouth-blown, hand-crafted result is a single solid piece of crystal reduced to just 13 mm thick in places, its square form with rounded corners evoking a slowly melting ice cube. The development took nearly four years of research. After blowing, the red-hot crystal is contoured into shape using a two-sided mould to control cooling and preserve tolerances. Production reaches 50 pieces per year in three latitude variants (references Q516511J, Q516512J, Q516513J). Pricing has not been officially disclosed.

Atmos Hybris Artistica Tellurium by Marc Newson

Here, the boundary between dial and case dissolves entirely. Newson designed a perfect sphere of glass engraved with a map of the 64 constellations visible in the Northern Hemisphere, set with 539 cabochon-cut sapphires totalling 32 carats that represent the principal stars. Achieving the illusion of “invisible setting”, with gemstones inset directly into the external surface of the glass, required extensive research and numerous iterations to perfect the technique. The clock rests on a laser-engraved plate reproducing the surface of the Moon, supported by a circular, ribbed base of dark-blue anodised aluminium that echoes the anodised blue of the dial.

Inside, Calibre 590 delivers its astronomical theatre on a translucent blue sapphire crystal disc laser-engraved with zodiac symbols. At the centre, a burst of sunrays in polished 18K pink gold represents the Sun, the longest ray pointing to the current zodiac sign. Earth and Moon rotate in three dimensions; Earth turns on its axis every 24 hours while the Moon orbits in a synodic month of 29 days, 12 hours, 44 minutes and 2 seconds.

Calibre 590 is the most complex Atmos movement ever built. It unites a tellurium with month, season and zodiacal calendar indications, plus a moon phase that deviates by only one day every 5,770 years. The finish choices reflect Newson’s preference for contemporary aesthetics: galvanised aluminium on the hours-and-minutes ring, brushed surfaces on the movement plates and balance wheel. The three-dimensional Earth is hand-painted in miniature by Jaeger-LeCoultre‘s Métiers Rares™ atelier; the Moon surface uses laser engraving; and meteorite, a material literally fallen from space, is inlaid on the Earth-Moon ring.

The plinth is blue calf leather, part of a modular case designed by Newson and handcrafted by Serapian, the Milanese leather workshop, using their signature Mosaico hand-weaving pattern developed by the Italian firm in 1947. This breathtaking piece measures 270 x 285 mm and comes as a limited edition of just three pieces (reference Q5765310). Pricing has not been officially announced.

Memovox Travel Clock by Marc Newson

The dial of the Memovox Travel Clock builds on Newson’s signature visual language of circles within circles. Arabic numerals dominate the centre, surrounded by a mobile central disc carrying the Memovox’s emblematic triangular alarm pointer, with minutes marked on a fixed outer ring. The power reserve display is the star technical element on the dial: 12 narrow apertures form a broken circle around the numerals, each representing one day of reserve. When fully wound, all 12 indicators glow orange; as each day passes, the corresponding indicator turns blue using a patented mechanism comprising two intertwined helicoidal rings, one mobile in orange and one fixed in blue. Hands and alarm triangle use SuperLuminova® for low-light legibility.

Calibre 256 is an entirely new, in-house, manually wound movement. Two large barrels power the timekeeping function, delivering an exceptional 12-day power reserve, and a third barrel operates the alarm exclusively. The movement integrates the Memovox alarm complication, a lineage stretching back to 1950, with its distinctive school-bell tone. A peripheral winding crown concealed beneath the bezel allows time-setting, winding, and alarm-setting, with function selection via an integrated selector button. The caseback carries a central alarm power reserve indicator and engraved year and series details.

Titanium forms the 69 mm diameter, 18 mm thick spherical case, combining lightness with structural resilience. A folding stand integrates into the caseback for desk or bedside use. Newson’s collaboration extended to Schedoni, the historic Modena leather workshop, who crafted a complete travel kit from tan-coloured, natural open-pore cowhide with contrasting beige hand-stitching: a travel pouch, a travel pack accommodating three wristwatches, a magnifying glass, strap removal tool, screwdriver, and a dedicated display stand. Production is limited to 100 numbered pieces per year (reference Q614T020). Pricing has not been officially disclosed.

Atmos Régulateur Enamel Colibris

This clock demands attention with its Grand Feu miniature-painted panels depicting hummingbirds hovering among cherry blossoms and hydrangeas against a deep-green background. The dial and two panels required 45 separate Grand Feu enamel firings in total: 15 layers for the dial and 15 layers for each panel, each firing at 800°C or above carrying the constant risk of cracking, bubbling or contamination that could destroy all preceding work. The large panel surfaces, each measuring 196 mm x 105.2 mm, use the “dry enamelling” technique, sifting powdered pigment onto steel bases. Steel was chosen specifically for its resistance to repeated high-temperature firings. The hour and minute markers use gold-leaf paillonné technique, where tiny fragments of gold leaf are cut to precise shapes, placed in position, then sealed under layers of translucent enamel. The entire decorative enamelling required 230 hours to complete.

Calibre 582, a mechanical perpetual movement, delivers regulator-type separated displays of hours and minutes, a 24-hour indication, month display, and a perpetual moon phase accurate to one day in 3,821 years. The movement architecture organises its layered concentric displays around three open-worked guide rollers arranged in a pyramid formation, with arc-shaped bridges supporting a suspended 24-hour ring. The inner glass cabinet measures 468 mm x 183 mm x 255 mm overall, with the movement suspended within and the enamelled panels flanking it on both sides. The base and feet receive PVD coating with rhodium-plated details (reference Q5604305). This piece is a limited edition of three. Pricing has not been officially confirmed.

Atmos Régulateur Wood Marqueterie

Where Enamel Colibris favours lush naturalism, Wood Marqueterie opts for geometric rigour. The decorative panels feature a trompe l’oeil pattern of apparently infinite depth, created from 52 slices of predominantly walnut veneer, each no thicker than 0.6 mm, hand-cut with micron precision and individually hand-tinted in shades of blue ranging from light grey-blue through sky blue to deep ocean blue. The process took 50 hours in total. Metal ribs on the rhodium-plated base material define the pattern’s geometry after the channels were hollowed out to receive the wood. Once inlaid, the surfaces were varnished and polished to a contemporary finish with strong Art Deco resonance. The dial continues this language: the large minutes register is blue-lacquered with rhodium-plated applied indexes, the hours register reverses the palette with an opaline background and blue-lacquered indexes, and the moon phase display sets a polished moon against a blue-lacquered sky, with cloud details worked in azurage for a finely textured finish.

Calibre 582 powers this piece identically to its Enamel Colibris sibling: regulator display, 24-hour indication, month display, and perpetual moon phase accurate to one day in 3,821 years. The overall cabinet dimensions match at 468 mm x 183 mm x 255 mm, with a rhodium-plated base and feet carrying brushed and satin-polished finishes (reference Q5556304). Production extends to a slightly larger limited edition of five pieces. Pricing has not been officially confirmed.

Jaeger-LeCoultre at Milan Design Week 2026

A Perpetual Statement

Five clocks, five different dialects of the same creative language, and a single conviction that sits at the heart of everything Jaeger-LeCoultre does: that time, in the right hands, becomes art. The Perpetual Timekeeper at Villa Mozart was not an exercise in nostalgia; it was a forward-looking declaration about the enduring relevance of mechanical ingenuity, hand craftsmanship, and bold design thinking. Newson said it best himself: working with Jaeger-LeCoultre “remains a dream.” After seeing these five pieces, it is very hard to disagree.
