The Master Ultra Thin Heritage: Jaeger-LeCoultre’s Vision of Ultra-Slim Elegance

Born from more than a century of expertise in crafting ultra-thin calibres, the Master Ultra Thin collection embodies the very essence of Jaeger-LeCoultre’s horological elegance. As early as the 1900s, the Manufacture distinguished itself in this field, culminating in 1907 with the creation of the legendary calibre 145, nicknamed “Knife,” which was then the thinnest movement in the world. This technical achievement left a lasting mark on the identity of the Maison and inspired the creation, in 1993, of the Master Ultra Thin line as we know it today.

In this tradition, every model of the collection is designed to express discreet sophistication: pure lines, perfectly balanced proportions, remarkable thinness, and an aesthetic that remains timeless through the decades. Jaeger-LeCoultre distills into it all the elements that define its signature: precision, sobriety, mechanical excellence, and visual harmony.

This new limited edition, featuring an unprecedented grained copper dial, reaffirms this philosophy while adding a subtle contemporary touch. A luminous and warm interpretation that beautifully revisits one of La Grande Maison’s most elegant classics.

A Grained Copper Dial with Striking Depth

At the heart of this new limited edition lies a completely new grained copper dial, a true aesthetic signature of the piece. Jaeger-LeCoultre offers here a contemporary take on the salmon tone so beloved by collectors, enhanced by a matte and subtly textured finish that transforms with every shift of light. Depending on the angle, the surface moves between a soft, powdery hue—almost a rosy ivory—and a deeper, more vibrant copper, offering a truly unique visual presence on the wrist.

This textured surface deliberately breaks away from the traditional finishes of the collection—silver, blue, or black sunray dials—to introduce a tactile and modern dimension, rarely seen in the realm of ultra-thin dress watches.

The elongated trapezoid hour markers, perfectly polished, stand out clearly against this warm background. The Dauphine hands follow the Maison’s signature dual-faceted construction—one satin-brushed, the other polished—creating subtle and constant light play. Together, they form a highly legible dial, where each element seems carefully sculpted to capture the light with precision.

Finally, the minute track punctuated with small black dots adds a discreet graphic touch, while the overall composition retains an almost minimalist harmony. Rarely has a copper tone found such balance within a stainless steel case—an elegant combination mastered by only a few great maisons, and one Jaeger-LeCoultre elevates here with undeniable finesse.

A Stainless Steel Case with Ideal Proportions

The Master Ultra Thin Date remains faithful to the timeless aesthetic that defines the collection. Its polished stainless steel case, pure and refined, offers a remarkable balance between thinness, modernity, and classic elegance. With a perfectly judged 39 mm diameter, the watch stands as a universal dress piece, suitable for all wrists while maintaining a refined and discreet presence.

The slim profile of just 7.9 mm testifies to Jaeger-LeCoultre’s historical expertise in the field of ultra-thin watchmaking. This remarkable thinness allows the watch to slip easily under a shirt cuff while reinforcing the natural elegance expected from a perfectly executed dress watch.

The subtly curved lugs—one of the line’s hallmarks—hug the wrist with great comfort. Paired with a new brown alligator strap, warm and richly toned, the watch gains in sophistication and chromatic harmony: this elegant brown echoes the copper nuances of the dial while contrasting gently with the polished steel. Equipped with a stainless steel folding clasp and an interchangeable system, the strap enhances both versatility and everyday comfort.

The fully polished case captures the light with finesse, creating a delicate contrast with the matte, grained copper dial. This interplay—cool steel against warm copper, polished surfaces against textured grain—gives the watch a character that is both modern and timeless.

This harmonious construction, free of excess or stylistic complication, reminds us that at Jaeger-LeCoultre, aesthetics always serve sobriety and precision. A watch thoughtfully designed, where every line naturally finds its place.

A Discreet and Perfectly Integrated Date Function

Faithful to the philosophy of the collection, the Master Ultra Thin Date favors a clean and functional approach to the calendar complication. No artifice or visual clutter: the date display rests in a rectangular aperture positioned at 6 o’clock, a signature choice of Jaeger-LeCoultre’s most balanced creations.

The crisp opening preserves the softness of the grained dial while introducing a contemporary touch through a contrasting white date disc. This intentional contrast enhances legibility without disrupting the watch’s harmony and visually echoes the black dots of the minute track. The discreet frame around the aperture contributes to the dial’s elegance while reinforcing the perceived precision of the display.

Its low positioning contributes to the vertical symmetry so characteristic of the Master Ultra Thin line—an aesthetic signature that balances the dial and ensures immediate clarity. Simple in appearance, this date display actually reflects Jaeger-LeCoultre’s mastery in integrating essential functions without compromising purity.

A Showcase of Exceptional Watchmaking Under Sapphire

At the heart of the Master Ultra Thin Date beats the Jaeger-LeCoultre calibre 899, an ultra-thin automatic movement entirely designed and assembled within the Manufacture in the Vallée de Joux.
Visible through the transparent sapphire caseback, it reveals all the beauty of the Maison’s artisanal craftsmanship: beveled bridges, blued screws, Côtes de Genève, and a finely decorated mainplate.

This ultra-thin calibre—born from decades of expertise—offers a 70-hour power reserve and ensures outstanding precision while maintaining an exceptionally slim profile.

Before leaving the Manufacture, each watch undergoes Jaeger-LeCoultre’s 1,000-hour internal control, a unique protocol in the industry that certifies the reliability, resistance, and chronometric stability of every creation.

Through this visible mechanism, the Master Ultra Thin Date expresses everything that makes Jaeger-LeCoultre unique: technical mastery, an acute sense of detail, and effortless elegance.
A watch designed to stand the test of time—in every sense.

An Iconic Configuration, Future Collector?

With this new Master Ultra Thin Date, Jaeger-LeCoultre presents a rare and highly desirable interpretation of the contemporary dress watch. Its grained copper dial—between modern salmon and vintage warmth—belongs to an aesthetic tradition cherished by great maisons, yet used sparingly. Paired with a stainless steel case, this iconic combination instantly recalls the most sought-after classic watches, those whose chromatic balance naturally endures through the ages.

Released as a limited edition of just 800 pieces, each model carries the exclusivity of a “One of 800” creation, strengthening its appeal among enthusiasts and collectors seeking configurations that are both rare, refined, and immediately recognizable. Sobriety, finesse, horological tradition, and subtle modernity: this Master Ultra Thin Date brings together everything that defines Jaeger-LeCoultre’s strength—offering a version that may well become one of the most coveted in the line.
