“The theme of this year’s Valley of Inventions is our directional creative line,” explains Jérôme Lambert. “It tells us a lot when it comes to organising the reveal and the choice of the watches that come into view. It allows us to underline two things: the origin and the spirit of invention. It’s what we came through, and what we try to make exemplary through the watches presented this year.”
The Craft Behind the Innovation
This reverence for heritage and innovation was palpable throughout the Maison’s immersive booth experience, one of the fair’s most compelling destinations.
Jérôme believes much of that fascination lies in the tangible authenticity of traditional watchmaking.
“It shows the interest for this old-fashioned, real thing,” he says, pointing to the century-old guilloché machines demonstrated on-site, which remain integral working tools within the Manufacture.
“These machines are very rare, and they cost a fortune. It takes years to find one, then years to restore it, and then time again to master it completely. But once you do, you’re creating things that modern machines simply cannot reproduce.”
That philosophy extends to the Maison’s continued investment in Métiers Rares™, where preserving artisanal skill means far more than safeguarding techniques. It is equally about the people capable of reviving and reinventing them.
Forged by harsh winters and isolation, the valley shaped a culture of resilience and ingenuity that gave rise to the Maison in 1833. This spirit of invention – now reflected in more than 430 patents and 82 ateliers – defines the theme for 2026’s The Valley of Inventions, celebrating the birthplace of modern precision watchmaking.
“They train again to use them, and they reinvent the way of doing it,” Jérôme says.
“When you visit the Manufacture and see the 82 ateliers, 108 watchmaking métiers, and 69 signature savoir-faire under one roof, you understand how far these crafts feed one another.”
This spirit of creative exchange is central to Jaeger-LeCoultre’s artistic identity. In the open-plan Rare Crafts atelier, enamellers, engravers, and gem-setters work side by side, inspiring one another in real time.
That interplay between engineering and artistry finds perhaps its boldest expression in this year’s showpiece, the Master Hybris Inventiva Gyrotourbillon À Stratosphère.
The Power of Emotion
For Jérôme, innovation is only meaningful if it sparks an emotional response.
“We are looking for that famous emotion of a first time,” he says. “If what we do with the techniques creates that electricity at the top of your shoulders, then we are right in what we wanted to create.”
It’s a strikingly human way of describing haute horlogerie – less about mechanics for mechanics’ sake, and more about visceral connection.
When asked which of this year’s launches moved him most, his answer came instantly: the Gyrotourbillon.
“When you watch the tourbillon turning on itself, it moves you.”
That emotional lens also informs Jaeger-LeCoultre’s technical advancements, including the enhanced precision guarantees behind the latest Master Control Chronometer pieces.
Jérôme notes that today’s watches face far harsher daily conditions than they did even two decades ago – from airport X-ray scanners to magnetic exposure and extreme travel environments.
For the Maison, innovation in precision is less about responding to collector demand than adapting to the realities of modern life.
Yet perhaps the most revealing insight came when the discussion turned personal.
Asked whether mechanics, artistry, or craftsmanship resonates most deeply with him, Jérôme’s answer was unequivocal.
“I would start with the people behind the craft. Then I would say it’s the history. These watches are testament to 193 years of watch manufacture for Jaeger-LeCoultre. For me, it’s the story.”
In an industry obsessed with specifications, it was a reminder that the most enduring complications are measured as much by the feeling they evoke as by the mechanics they master.
