HARMONY OF STARS AND SOUND
In the heart of the Swiss Jura, the Vallée de Joux embraces a serene and calm atmosphere through its forests and mountains. The sky’s purity reveals its most profound mysteries, making it the ideal place for astrologers to study the astral phenomenon.

MINUTE REPEATER MASTERY
Over the past 150 years, minute repeaters have had a major presence in Jaeger-LeCoultre’s portfolio of complicated timepieces. La Grande Maison’s mastery of chiming watches is confirmed by more than 200 calibres, including some 100 minute repeaters made before the year 1900. Since the mid-1990s, when Jaeger-LeCoultre revived this noble horological legacy, its engineers and designers have worked to redefine the benchmark for acoustic quality, harnessing technology to serve and safeguard horology’s most treasured traditions.

Considered by watchmakers to be the most challenging – and rewarding – of all horological complications to master, a minute repeater is not only a timepiece but also a miniaturised musical instrument. One of the most important elements of a chiming watch is the way in which sound is transmitted from within the watch to be heard by the human ear. The calibre 945 gathers all the accumulated expertise in chiming mechanisms of the Grande Maison, since its foundation in 1833.

One of the most important elements of a chiming watch is the way in which sound is transmitted from within the watch to be heard by the human ear. Capitalising on the superior acoustic qualities of synthetic sapphire crystal, Jaeger-leCoultre’s patented ‘crystal gongs’ (introduced in 2005) are soldered directly to the sapphire crystal, which acts as an amplifier. The square-profile gongs introduced two years later provide a flat striking surface for the hammers, ensuring more consistent and powerful strikes, while the additional material provides a greater vibrational mass and thus a fuller sound.

ASTRONOMICAL WATCHMAKING
The new Master Grande Tradition Grande Complication embodies Jaeger‑LeCoultre’s mastery of astronomical complications in its celestial vault complication. As well as turning on its own axis in 60 seconds, the tourbillon makes a complete, anti-clockwise circuit of the dial in one sidereal day. Slightly shorter than a solar day (on which we base civil timekeeping), a sidereal day is based on Earth’s rotation measured relative to the ‘fixed’ stars.

Civil time is read on the two concentric rings that complete the dial: applied hour indexes on the first ring and minutes on the silvery-white outer ring.

Slightly shorter than a solar day (on which we base civil timekeeping), a sidereal day is based on Earth’s rotation measured relative to the ‘fixed’ stars, which takes precisely 23 h, 56 min and 4.1 seconds. The sidereal day is used by astronomers to follow the apparent movement of the stars across the night sky.

Ensuring the utmost precision of the watch, the Orbital Flying Tourbillon makes a complete, anti-clockwise circuit of the dial in one sidereal day.
INNOVATIVE DESIGN
An exceptional movement merits an exceptional habillage and the new Master Grande Tradition Grande Complication brings fresh artistic expression to this marriage of complications. A multiple-level dial amplifies the beauty of the celestial theme while also showcasing the orbiting tourbillon. The delicate filigree which forms a dome, represents the connection between astronomy and horology. This structure echoes the pattern of the constellations, which highlights the complications of this calibre.

The Master Grande Tradition case is a perfect complement to the artistry of the dial and the sophistication of the movement. Comprising more than 80 parts, its convex bezel is complemented by broad bevels on the lugs; the hollowed-out sides of the lugs add dynamic tension, while the repeater slide is tapered to harmonise beautifully with the curving case sides.

On the deepest level of the dial, a midnight blue or black disc (depending on the model) is decorated with tiny stars. Above it, a delicate filigree forms a dome, its structure echoing the pattern of the constellations marked on the convex celestial disc. The star chart depicts the Northern Hemisphere night sky, as seen from the 46th parallel – the latitude of Jaeger-LeCoultre’s home in the Vallée de Joux.
The new Master Grande Tradition case, introduced in 2019’s two minute repeaters, is a perfect complement to the artistry of the dial and the sophistication of the movement. Different surfaces are micro-blasted, polished and satin-brushed to maximise the play of light and emphasise the details.
