L.Leroy Elyor Tourbillon

L.Leroy enters a new era of renewal and, at Geneva Watch Week 2026, unveiled its latest tourbillon watch: Elyor. A timepiece that pays tribute to the Maison’s centuries of excellence.

When artistry, aesthetics, engineering, and innovation come together in watchmaking, creations that go beyond the mere measurement of time are born. In this spirit, Maison L. Leroy presents the new tourbillon Elyor, a tribute to the purest tradition of Haute Horlogerie.

The appellation “Elyor” derives from the anagram of Leroy. During the Reign of Terror of the French Revolution (1793-1794), Leroy - whose surname sounded too regal - signed his creations with the anagram “Elyor” to escape harassment from revolutionaries inflicted on suppliers to the king and court.

The latest addition to the classic Osmior collection, Elyor encapsulates the brand’s refined, centuries-old heritage, which has always been synonymous with precision, elegance, cutting-edge technology, and artisanal know-how.

Dating back to 1785, when Basile Charles Leroy founded his watchmaking workshop in the Galerie de Pierre at the Palais Royal, L.Leroy boasts an illustrious and noteworthy heritage. Appointed Watchmaker to the Empire during the reign of Napoleon I and to Her Majesty Queen Victoria of England, L.Leroy left an indelible mark on the domain of Haute Horlogerie and French chronometry, winning an impressive 384 gold medals in chronometry competitions. For over two hundred years, the Maison has created countless masterpieces, with the Leroy 01 being a remarkable highlight. This exceptional timepiece not only won first prize at the Paris Universal Exhibition in 1900 but also held the title of the most complicated watch in the world until 1989. Renowned figures such as Proust, Matisse, Napoleon, Queen Victoria, Chopin, and Roosevelt — to name just a few — all owned L. Leroy timepieces.

On the 240th anniversary of its founding, L.Leroy reaffirms its identity as the guardian of an extraordinary heritage and an active player in contemporary watchmaking. Embodying a distinguished legacy of technical achievements, prestige, and passion, the Elyor tourbillon stands as a testament to the continuity of an extraordinary heritage that has spanned the centuries with elegance and mastery.

A masterpiece of time, three distinct personalities

The Elyor is a true masterpiece of time, designed for those who appreciate the allure of technical sophistication encased in a classically refined aesthetics.

This latest version is manufactured in a small number of units and is offered in three different versions. It features a tambour-shaped case, traditionally reserved by the brand for its classically styled timepieces, and measures 42 mm in diameter with a thickness of just 11.88 mm, including the domed sapphire crystal glass.

Its graceful lines, harmonious proportions, immaculate finishing, and use of noble materials such as 18k 5N red gold and platinum, along with the more contemporary grade 5 titanium, reflect L.Leroy's meticulous attention to detail.

Each configuration carefully highlights chromatic contrasts, aesthetic balance and the sophisticated elegance that defines the new Elyor range. The multi-layered dial, which comes in three different shades, identifies each piece in this newborn line. The satin-finished hour track on the titanium model features an evergreen silver hue and L.Leroy’s signature applied Arabic numerals. The precious platinum version is paired with a light, sky-blue dial, obtained through ALD treatment, and applied Arabic numerals, evoking the clarity of a cloudless day. Finally, the 5N gold case is combined with an anthracite dial with golden accents.

The centre of the dial boasts a refined “Clous de Paris” motif. A distinctive mark of luxury watchmaking in centuries past, it continues to be a highly prized technique today, mainly used on watches with a classic feel. Its decorative texture, made up of a network of small pyramids that stand out from the surface, captures the light, creating nice reflections and making the display look more 3D.

Apart from the beauty of its finishes, the real star of the dial is undoubtedly the eye-catching flying tourbillon positioned at 6 o'clock. Visible through an opening that showcases its complexity and allure, it is adorned with a mirror-polished titanium bridge bearing the intertwined double “L” monogram. This technical yet poetic complication is the answer to the longstanding challenge in watchmaking of counteracting the negative effects of gravity on the regulating organ — that delicate mechanism that marks every beat of time — to achieve optimal timekeeping precision. A glance at the tourbillon cage is enough to be captivated by its rotation. It accomplishes one revolution per minute, and its uninterrupted motion evolves into a mesmerizing spectacle, suspended between mechanics and poetry.

Elyor: three versions, one essence. A timepiece crafted for aficionados and collectors who seek more than mere timekeeping functionality. It is for those who yearn for an objet d'art that evokes emotion and speaks of meticulous craftsmanship, artistic expression, time-honoured tradition, and avant-garde innovation.

A reliable, high-performance mechanism

At the core of the Elyor - indicating central hours, minutes, and seconds - is the L.Leroy L600 automatic calibre, developed exclusively for L.Leroy in Geneva.

Comprising no fewer than 288 components, this high-performance self-winding movement with a flying tourbillon features a variable-inertia balance-wheel operating at 21.600 vibrations per hour (3 Hz). For the first time in the brand’s history, it integrates a micro-rotor, whose high-efficiency winding system delivers a substantial 60-hour power reserve.

This component, which began to make its first appearances around the mid-1950s, allows for a more compact and elegant movement construction. Unlike conventional oscillating weights, the micro-rotor is integrated directly into the movement’s mainplate, significantly reducing overall thickness while preserving — and even enhancing — the visibility of the calibre’s hand-finished decoration, a key element for discerning collectors.

The rotor itself is crafted from Inermet, a tungsten-based alloy. Owing to tungsten’s exceptionally high density, the micro-rotor ensures optimal winding efficiency despite its reduced dimensions.

The flying tourbillon, positioned at 6 o’clock, performs a complete rotation on its axis every 60 seconds, contributing effectively to the compensation of gravitational effects on the regulating organ. This mechanism—among the most complex to manufacture in the field of micromechanics - is entrusted exclusively to highly skilled watchmakers capable of assembling and regulating it within extremely tight tolerances.

The tourbillon cage comprises 78 components, meticulously assembled to optimize both kinetic stability and chronometric efficiency. The mechanism is topped by a grade 5 titanium upper bridge, mirror-polished to Haute Horlogerie standards. This bridge has been specially shaped to echo the Maison's logo, combining aesthetics and functionality within a unique mechanical architecture.

In the realm of high-end watchmaking, the mechanical movement is conceived not only as the functional heart of the watch, but also as an expression of decorative expertise and brand identity.

The high level of artisanal savoir-faire is reflected in the quality and array of finishes — such as the perlage on the main plate, the refined frosted decoration on the rhodium-plated bridges with hand-polished and bevelled edges, the mirror-polished screw heads, the gilded micro-rotor bearing a raised logo and enriched with a geometric arrangement of satin-finished elements forming sandblasted recesses. This ensures that engineering mastery and beauty are perfectly combined in a coherent and harmonious whole.

This refined artistry is revealed through the sapphire crystal porthole on the case back, secured by a ring crafted from the same materials as the case. This ring has a particularly complex structure, with frosted segments and polished profiles and engravings in relief that constitute the passport of each creation.

This latest timepiece in the Osmior collection fastens to the wrist with an elegant black large-scale alligator leather strap, lined with small-scale alligator leather. It is secured by a deployant clasp crafted in the same metal as the case, personalized with the brand’s distinctive double “L” logo embraced within a circle — a detail that lends the design its exclusive and original character.

The Elyor, with its tourbillon complication, embodies a legacy that spans centuries, where the spirit of L.Leroy continues to beat at the heart of every timepiece brought to life. The result of a harmonious fusion between centuries-old expertise and contemporary ingenuity, this watch elevates the art of timekeeping. A tribute to the passage of time and to the eternal value of every precious moment.
