AN OPEN-WORKED MASTERPIECE COMBINING A FLYING TOURBILLON WITH A MINUTE REPEATER IN AN ULTRA-THIN AUTOMATIC MOVEMENT
KEY FACTS:
Beyond skeletonised movement: artistic open-working and sapphire bridges reveal the beauty of the calibre’s 593 components
Ultra-slim calibre: a high-complication automatic calibre 5mm thick, in a case 8.25 mm high by 41.4 mm in diameter
Complex case construction: a new 60-part case, masterfully adapting the iconic Master Grande Tradition codes – a first exclusive tailoring for Calibre 362
The thinnest automatic minute repeater tourbillon: conceived as a fully integrated movement where the minute repeater forms an intrinsic part of the architecture
Representing a major technical breakthrough and an innovative aesthetics when it was introduced in 2014, Calibre 362 draws upon Jaeger-LeCoultre’s remarkable heritage in two key areas: chiming complications and precision timekeeping. It remains the world's thinnest automatic minute repeater tourbillon.
LIGHTNESS, TRANSPARENCY AND VISUAL CONTRAST
This Hybris Mechanica Edition of Calibre 362 has been designed to showcase the entire movement - its assembly alone requires seven weeks - revealing the delicacy of its 593 components, including the entire operating sequence of the minute repeater mechanism and the captivating dance of the tourbillon.

To reveal and amplify this beauty, skeletonisation – meaning creating openings within the existing bridges of the Calibre – would be the traditional means. However, for Jaeger-LeCoultre, this was not sufficient, as the structural parts of the bridges and plates, which are essential for a movement's function, would still limit the visibility of part of the Calibre.
Sapphire Bridges, an innovative solution: Three bridges, essential for the structural stability of the movement, are meticulously constructed from transparent sapphire crystal rather than metal. This represents a significant accomplishment for the Maison, as creating sapphire bridges directly within the movement presented several technical challenges, notably the precise setting of its all-important 11 ruby jewels. Since direct setting into the sapphire was not feasible, 18K Pink Gold (750/1000) chatons were ingeniously employed – a technical feat that not only resolved the challenge but also enhanced the calibre's aesthetic beauty. To enhance their transparency and visual purity, the sapphire bridges are finished with polishing, anti-reflective coating, and an anti-static treatment.
14 different decorative techniques: The calibre's aesthetic brilliance is underscored by various finishes, including those on the case: sandblasting, perlage, polishing, flat polishing, straight graining, linear brushing, circular brushing, Côtes de Genève, diamond polishing, snailing, sunray brushing, bevelling, and guillochage. The exceptional precision of this hand-finishing is evident across all components, from the hand-bevelling and perlage to the varied brushing and polishing on diverse surfaces. This dedication to detail is exemplified by the 48 inner angles and 60 hand-bevelled components that adorn the movement.
An exceptional dial: The dial is elegantly complemented by an 18K Pink Gold (750/1000) case, distinguished by a variety of surface finishes that enhance the play of light across its contours – an aesthetic approach newly introduced for this calibre. Encircling this intricate display, the dial is pared back to form an open-worked ring of 18K White Gold (750/1000) around the movement’s periphery, revealing the elegantly guilloché in-house 18K Pink Gold (750/1000) winding rotor, a masterpiece crafted within Jaeger-LeCoultre’s Métiers Rares™ ateliers. To create visual contrast, the applied hour markers in 18K Pink Gold (750/1000) and the Jaeger-LeCoultre logo are matched with the hands and the winding rotor.
The art of integration: The complex case, designed and reinterpreted for the ultra-slim Calibre 362, is composed of 60 parts. Developed for the original Calibre 362, an innovative alternative to the conventional slide that activates a minute repeater combines a patented, retractable button at 10 o’clock that activates the function with a second button at 8 o’clock that locks and releases it. These buttons have been redesigned particularly for Hybris Mechanica Calibre 362 to integrate perfectly into its new case.
A MASTERPIECE OF TECHNICAL INVENTIVENESS AND THINNESS
Testament to the Manufacture’s enduring quest to create the ‘perfect’ chime, the minute repeater of Calibre 362, made of 187 components, features a striking mechanism designed from its inception in harmony with the regulating organ and automatic winding system. This design enables both exceptional acoustic performance and extreme thinness. Integrated directly into the calibre’s main structure, the minute repeater features one-piece, square-profile gongs optimised for tonal purity and resonance. These are paired with articulated trebuchet-style hammers that strike the gongs with greater velocity and precision, generating a sound that is at once powerful and refined.

Invented specifically for Calibre 362, the Manufacture’s patented silent time-lapse reduction mechanism further exemplifies this philosophy of integration. By dramatically minimising the pause between the hour and minute chimes – particularly in the absence of a quarter-hour strike – it ensures a fluid, uninterrupted acoustic sequence.
The transparency of the flying tourbillon is enhanced by both the cutaway in the base plate and the absence of cocks or bridges holding it in place, as well as the patented flying balance wheel. To ensure slimness while ensuring the most concentric ‘heartbeat’, and therefore timekeeping accuracy, Jaeger-LeCoultre’s engineers invented and patented the S-shaped hairspring, which is also fully visible thanks to the absence of a tourbillon bridge. The invention of this novel spring shape was necessitated by the particular construction of the tourbillon and the requirement for overall slimness of the calibre.

Three key innovations have made the technical beauty and complexity of Calibre 362 possible within an ultra-thin self-winding movement measuring just 5 mm in height.
The oscillating weight that winds the mainspring is designed as a peripheral rotor, with the dual benefit of adding no thickness to the calibre while also making the beauty of the movement fully visible from both the dial side and the back of the watch. Mounted on 36 specially conceived ceramic ball bearings and activated by the movement of the wearer’s wrist, it moves freely in both directions for optimal winding efficiency.
