Jaeger-LeCoultre Factory Visit: Where the Heart is


Jaeger-LeCoultre Factory Visit: Where the Heart is


What Jaeger-LeCoultre presented at this year’s SIHH was testament to the technical prowess of the 186-year-old maison. Namely, one of the major highlights uttered on everyone’s lips was the Master Grande Tradition Gyrotourbillon Westminster Pérpetuel (Hybris Mechanica 13). A watch with a name nearly as complex in styling as its movement. At first glance, it’s a breathtaking view of skeletonised inner workings that’s been modernised with touches of blue (with another version in a silver-grained dial). One’s eyes are immediately drawn to the hand-hammered finishing on the date wheel and trebuchet hammers, the blued square-shaped gongs, and not forgetting the cherry on top, the multi-axis tourbillon. It’s a lot to take in, even more so when one flips it over. There’s an almost symmetrical arrangement with the exceptional finishing on the bridges, holding together the myriad components that detail the behemoth of the caliber 184.

Master Grande Tradition Gyrotourbillon Westminster Pérpetuel

The Gyrotourbillon series is one of Jaeger-LeCoultre’s three masterful creations (the other two being the Duomètre and the Grande Sonnerie) that establishes the manufacturer to not just be a producer of skilful complications in pretty watches but to be purveyors of precision as well. Since its debut of the Gyrotourbillon in 2004, the Hybris Mechanica 13 is more than just the fifth iteration of the multi-axis tourbillon. It encapsulates the previous generations of grand complications to ever emerge from its doors at Le Sentier.

For more than a century, Jaeger-LeCoultre has been considered one of the pioneers in the watchmaking industry with notable innovations. Today, standing in Le Sentier with 25,000 square metres of space, the manufacture houses more than 1,200 staff. They were the first in the Vallée de Joux to incorporate all departments in the same building under the management of father and son, Antoine and Elie LeCoultre, and it was on these grounds where more than 1,200 in-house movements were developed.

The original manufacture

As we traversed through the manufacture, the bright midday sun bounced off the opaline white snow and spilled through the clear glass windows, birthing the interior with harsh light and strong shadows. Its modern architecture was undoubtedly beautiful, yet it buried any hint of the brand’s historical beginnings. It was only when we reached the Grande Complication workshop that the spirit of Jaeger-LeCoultre was truly evoked. It is a rarity to meet a watchmaker who has lived through the life and times of the same watch manufacture, over 40 years in fact. Master watchmaker and inventor for Jaeger-LeCoultre, Christian Laurent established the Grande Complications workshop of the manufacture in 1988, even before the Les Manufactures Horlogères SA group was formed. He’s developed some of the brand’s finest complications such as the Reverso Minute Repeater (1994) and the Duomètre Spherotourbillon and most notably, the Gyrotourbillon.

Offering up his greatest hits, Laurent immediately began presenting Jaeger-LeCoultre’s finest high complications to us, including past Gyrotourbillons that led up to this year’s piece. “What we do here is try to evolve every single generation of Gyrotourbillon to improve precision,” says Laurent. “Sometimes even starting from zero and recreating totally something new rather than improving the tiny details.” Among them was the 2015 version of the Master Grande Tradition Grande Complication, that began with the first iteration in 2010 which formed the Master Grand Tradition line. Dominated by a blue sky chart dial speckled with constellations and a month indicator, an orbital flying tourbillon flies daintily overhead. From the case back, one can watch the hammers striking the crystal cathedral gongs of the Westminster Chime minute repeater complication.

With almost five decades of his life dedicated to watchmaking, Laurent shared that the approach to creating complications at Jaeger-LeCoultre has barely changed since 30 years ago. “Until the ’80s, we were mostly focused on perpetual calendars. Then we pursued the Gyrotourbillon, keeping in the mind the same line of ideas we’ve always had. And that, until today, is to combine the culture of precision.” For instance, Jaeger-LeCoultre is one of the few manufacturers which produce and assemble their own pallet fork, which regulates the escape wheel in a Swiss lever escapement. It’s a miniscule piece that mainly constitutes of an anchor, guard pins and levers. To view this piece in its entirety is to look at it under a microscope — it would sit on the edge of a fingertip if you picked it up. Putting it together is a nightmarish challenge. The shape of the anchor is first stamped out, then the guard pins are created (to position the anchor on a balance shaft), and then tiny pieces of rubies are used as the levers (to engage with the escape wheel). A natural resin glue called shellac is used to affix the rubies onto the anchor, and this gluing process is just one of the 22 operations that are carried out to finish the complete fork. But it’s exactly this form of handcrafted execution that has challenged Jaeger-LeCoultre to confront modern times with century-old Metiers d’Art techniques. “I can recognise the aid digital technology has provided to traditional watchmaking,” says Laurent. “Digital tools helped us develop the Gyrotourbillon 5 in under six years; it would have taken 10 otherwise. It also helps in watchmaking schools where learning is more comprehensive, so once these young watchmakers come to us, they’re able to give us what we need and they can start working on high complications a lot sooner.”

One of their newest extensions is the Heritage Gallery that was set up in 2017 and stands in the original place of Antoine LeCoultre’s first workshop in 1833. The archived walls are treasure boxes of Jaeger-LeCoultre’s history, with historical timepieces scattered throughout two floors. There was the vintage Memovox; the brand’s first and smallest 101 calibre; first Reverso Duo from 1994; a replica homage to Amelia Earhart whose historic flight from Mexico City to New York was engraved on a 1935 Reverso; all the Atmos clocks that ever lived, and Antoine LeCoultre’s invention (unpatented) of the lever-winding mechanism from 1847 in a pocket watch complete with an engraving of Elie LeCoultre’s name.

Yet Laurent looks to Jaeger-LeCoultre’s future that will only be made possible with its past. “There are two things that could hold back the development of new movements and complications: the entire evolution of quartz and digital watches, and also being hesitant to move forward while keeping the maison’s heritage and core values intact. Older pieces always have to be refreshed again, but the energy it takes to do simple changes is really where all the master know-how lies.” And with 48 years of watchmaking under his belt, passion was the only constant. “Today, digital watches are more of an aid to our daily lives. Ultimately, the art of traditional watchmaking will never be deterred by that because it will always be more emotional.”
