Jaeger-LeCoultre has unveiled three limited-edition timepieces that bring together haute horlogerie, celestial mechanics, complex chiming complications and high-jewelry craftsmanship.
The new releases comprise the Master Hybris Artistica Calibre 945, the Duometre Grande Complication à Grande Sonnerie and a new iteration of the 101 Secrets. Each takes a different approach to the manufacturer’s technical and artistic expertise, with production ranging from a five-piece edition to a unique single-piece creation.
Master Hybris Artistica Calibre 945
Leading the trio is the Master Hybris Artistica Calibre 945, limited to five pieces and presented as an artistic interpretation of celestial timekeeping.
Its 45mm case is crafted in 18K white gold and houses a multi-level domed dial depicting the night sky above the Vallée de Joux. The dial is executed in hand-crafted grisaille enamel, a technique dating to the 16th century that uses Blanc de Limoges white enamel to create three-dimensional chiaroscuro effects against a midnight-blue background.
A Northern Hemisphere sky chart tracks the real-time positions of the constellations, accompanied by the 73-component flying Cosmotourbillon. The mechanism travels counter-clockwise around the dial once every sidereal day, completing its cycle in 23 hours, 56 minutes and 4 seconds.
The celestial display is complemented by an integrated minute repeater. The mechanism uses patented Cathedral crystal gongs and Trébuchet hammers to produce its chime, adding an acoustic dimension to the astronomical presentation.
Duometre Grande Complication
The second creation, the Duometre Grande Complication à Grande Sonnerie, is produced as a single-piece edition and features an updated interpretation of Calibre 182.
The movement comprises 1,300 individual components and incorporates 15 complications. Its 45mm case combines 18K pink gold and titanium, housing a Westminster-style Grande and Petite Sonnerie that reproduces the four-note melody of Big Ben through four gongs and four hammers.
The watch employs Jaeger-LeCoultre’s dual-barrel Duometre architecture, separating the power used for timekeeping from that required by the chiming mechanism. A flying tourbillon accompanies a retrograde perpetual calendar designed to automatically account for leap years until 2100.
Acoustic performance is further enhanced by elongated metallic-glass gongs and a titanium inner case. The newly designed openworked blue-grey lacquered dial exposes the strike sequence governors beneath, making part of the chiming mechanism visible.
101 Secrets Returns in High Jewelry Form
Completing the trio is a new iteration of the 101 Secrets, limited to three pieces and crafted in 18K pink gold.
The double-rivière bracelet is set with 124 pink sapphires arranged in 10 sizes and seven shades, progressing from vivid cyclamen to pale blush. A contrasting border of grain-set white diamonds surrounds the gemstone arrangement.
The setting process requires 163 hours of work at the Métiers Rares™ atelier. Beneath the gem-encrusted links sits a white mother-of-pearl dial, concealed until a hidden button at 6 o’clock is activated, causing the watch face to open like a book.
At the centre of the creation is the hand-wound Calibre 101. Originally invented in 1929, the movement consists of 98 parts and weighs just one gram. It remains the world’s smallest rectangular mechanical movement in existence.
Together, the three watches demonstrate distinct facets of Jaeger-LeCoultre’s watchmaking approach, moving from astronomical displays and complex chiming mechanisms to high-jewelry craftsmanship. Their limited production further positions each creation as a highly exclusive expression of the manufacturer’s technical and artistic capabilities.
