In 2021, Jaeger-LeCoultre introduced the Reverso One ‘Precious Flowers’ series with models that united the codes of fine watchmaking, artistic crafts, and high jewellery to bring vivid colours along with an unparalleled level of sophistication to the Reverso One case. In 2025, two new models of exceptional beauty are being introduced: the Reverso One ‘Precious Flowers’ – Green Arums, and the Reverso One ‘Precious Flowers’ – Purple Arums. Exploring the beauty of flowers, both models are presented in pink gold (18k – 750/1000) cases and each will be produced in a limited edition of 10 pieces.

AN INSPIRED COLLECTION UNITING ARTISTIC CRAFTS WITH THE ICONIC REVERSO CASE

First introduced in 1931, the Reverso stood out as a quintessential example of Art Deco design. While initially created for the polo field, it quickly began to appear in feminine form, even before the first anniversary of its launch. A practical and elegant merging of aesthetic and function, its blank metal caseback was left free for the wearer to personalise – initially with an engraved message or lacquered motif. From those beginnings, the Maison has explored and developed the creative opportunities presented by the double-sided case (historical patent CH159982), unleashing the art of decoration.

The introduction of the Reverso One case, with its finer, more elongated proportions, provided an ideal canvas for adornment with rich colours and precious gems. The dial-side of the watch offers only a subtle hint of the resplendent decoration on the back: against a background of delicate mother-of-pearl,  brackets define the four corners of the dial – creating a frame for the numerals, transferred in the signature Reverso One font. The gadroons and lugs are highlighted by the sparkle of grain-set diamonds, and the winding crown is embellished with a reverse-set diamond.

Expressing the poetic and feminine theme of flowers, the Reverso One ‘Precious Flowers’ series has grown progressively to include white lilies, brightly coloured arums, tropical birds-of-paradise and hibiscus flowers. Each model is a unique work of art, brilliantly decorated with different techniques including enamelling, paillonnage, engraving, lacquering, and gem-setting, according to the model.

SHOWCASING THE CRAFTS OF CHAMPLEVÉ ENAMEL AND DIAMOND-SETTING

The 2025 Reverso One ‘Precious Flowers’ interpretations present an explosion of vivid enamel colours and brilliant-cut diamonds. Colourful bouquets of arums are created using the grand feu champlevé enamelling technique, a demanding five-step process that begins with the hollowing-out of the metal surface to leave only the outline of each flower or leaf. The shallow troughs are then filled with powdered glass enamel that must be fired at temperatures up to 800° Centigrade. Up to 10 coats of enamel and firings are necessary, one layer at a time, to achieve the desired tonal nuances, intensity and depth of colour. Requiring at least two years of rigorous training and experience to master this skill, an expert enameller knows almost instinctively the precise moment when the enamel must be removed from the kiln, to avoid flaws such as bubbles or cracks and – because pigments often change during the heating process – to acquire the desired colours.

For designs that incorporate diamonds, gem-setting can begin only after the enamel work is completed. This task is made more difficult because a gem-setter requires soft metal, whereas the pink gold has become hardened by the extreme heat of firing; it also requires an exceptional level of precision since the slightest mistake could compromise countless hours of enamelling work. To set the diamonds on the ‘Precious Flowers’ cases, both grain- and snow-setting techniques are used. Grain-setting frames the dial and highlights the geometry of the cases, while snow-setting transforms the metal areas between the flowers and leaves of the enamelled motif. Using diamonds of different sizes, in arrangements that are determined by the shape of the area to be set, the snow-setting technique creates an almost unbroken surface of light and sparkle that amplifies the fresh colours of the enamel.

To support the advancement of craft skills and sharing of ideas, Jaeger-LeCoultre has created a dedicated atelier within the Manufacture where all Métiers Rares™ (Rare Handcrafts) are performed: gem-setting, engraving and a wide range of different enamelling techniques. It is by working in such close proximity that the various specialised artisans in this atelier are able to have the necessary discussions and exchanges throughout the entire process of transforming unadorned metal surfaces into magnificent pieces of jewellery.

REVERSO ONE ‘PRECIOUS FLOWERS’ GREEN ARUMS

In a lengthy and carefully orchestrated process, three different artistic techniques have been brought together to create the Green Arums model. The Green grand feu champlevé enamelling process alone requires 15 hours of meticulous crafting. Surrounding the flowers and foliage, a total of 409 diamonds (2.59 carats) have been patiently and expertly set using the snow- and grain-setting techniques – a process requiring 45 hours.

Contrasting with the bright green tones of the enamel and adding depth to the motif, black lacquer is applied among the flowers and leaves. In a process demanding absolute precision, fragments of lacquered material are cut into the exact shape and size of the spaces to be filled and are then fixed into place.

REVERSO ONE ‘PRECIOUS FLOWERS’ PURPLE ARUMS

The Purple Arums interpretation offers a stunning cameo of purple, pink and green grand feu champlevé enamel, requiring a total of 30 hours to craft. The floral design wraps seamlessly around the case-sides, from the back to the bezel, covering curves and angles that add to the complexity of the artisans’ work, with snow-set diamonds covering the entire motif. With painstaking precision, a total of 637 diamonds (2.12 carats) are snow- and grain-set, requiring an additional 95 hours of work to complete.

These highly specialised crafts transform the two new Reverso One ‘Precious Flowers’ timepieces into stunning celebrations of nature and femininity. Fixed by shiny alligator straps that complement the enamel colours, these timepieces also highlight La Grande Maison’s technical watchmaking mastery, as they are run by the hand-wound Jaeger-LeCoultre Calibre 846, a movement shaped by the Maison especially for the Reverso.

Attesting to the Manufacture’s horological savoir-faire, artistic craftsmanship and jewellery-making skills, these new Reverso One timepieces pay homage to the women who continue to inspire Jaeger-LeCoultre.

For 2021 the Maison introduces four sparkling new Reverso One models that unite the codes of fine watchmaking, artistic crafts and High Jewellery to bring fresh colour, sophistication and glamour to the collection. The creation of these exquisite timepieces has brought together multiple artistic crafts – enamelling, engraving and gem-setting work – in a remarkable collaboration between highly skilled artisans who are at the peak of their powers.

Inspired by the decorative jewels worn in the 1920s, Jaeger-LeCoultre’s artistic team has created four exceptional models that celebrate the poetry of flowers, with two models in white gold and two in pink gold each showcasing rare handcrafts in different combinations.

The restrained elegance of the dials provides only a subtle hint that these are truly precious timepieces: the glow of white mother-of-pearl is accented by the numerals, and the golden brackets that define the four corners of the dial. It is the flip side of the case that gives full rein to the artistry and diverse skills that reside within the Jaeger-LeCoultre Manufacture, with multiple artisans applying different crafts, collaborating in a carefully orchestrated process over the course of many weeks and months. When working on such complex and collaborative projects, the artisans’ work must follow a strict order: engraving first, then enamelling – which requires multiple coats of enamel pigment to add richness, nuance and visual depth. After each coat is applied, the enamel must be fired to set the colour – an exacting process that takes many days. To complete the piece, the background is decorated with lacquer or mother-of-pearl, or is set with diamonds – according to the model.

Precious Flowers in four interpretations

White Lilies – symbolising purity, devotion and honour in the language of flowers – decorate a white gold case. The blank gold case-back has been relief-engraved – a technique by which the background metal is sculpted away, leaving only the raised outlines of the floral design. Each of the blooms is entirely hand-engraved, replicating the texture of lily petals in fine detail. Contrasting with the cool tones of the white gold, the leaves are enamelled in a rich blue and the stamens in light blue. To create the sky-blue background, tissue-fine wafers of mother-of-pearl are cut to the exact shape then laid in place. Grain-set diamonds embellish the entire case, wrapping seamlessly from front to back, and the winding crown is adorned with a reverse-set diamond.

Pink Arums – a symbol of admiration and appreciation – complement the warm tones of a pink gold case. With a black lacquered background providing dramatic contrast, the blooms are enamelled in graduated shades of pink, while the foliage is fully set with diamonds. The winding crown is adorned with a reverse-set diamond, and grain-set diamonds embellish the entire case, wrapping seamlessly from front to back.

Two fully diamond-set models also feature Arums: Purple Arums (on pink gold) symbolise charm and passion, and Blue Arums (on white gold) symbolise grace and refinement. On these two watches, the flowers and leaves are all enamelled, and the entire background is snow-set with diamonds – an exacting technique that requires approximately one hour to set just five or six stones. Altogether, the gem-setting on these pieces requires a total of 95 hours. The floral design wraps seamlessly around the case-sides, from the back to the bezel, involving curves and angles that add a high degree of complexity to the artisans’ work.

Set in the elongated Reverso One case and complemented by shiny alligator straps in vivid colours, these new timepieces are a joyous expression of feminine elegance. Naturally, given the Maison’s mastery of technical watchmaking, there has been no compromise on the movement, and Reverso One Precious Flowers introduces the hand-wound Jaeger-LeCoultre Calibre 846, a rectangular shaped movement developed especially for the Reverso.

To be made in an edition of just 10 pieces of each model, every one of these miniature works of art is subtly different – their fine detailing and nuanced colour palettes the product of each artisan’s particular gestures, expressing their passion and personality, as well as their remarkable skill.

Conceived as an ode to 21st-Century femininity, these new Reverso One timepieces attest to the horological savoir-faire, artistic craftsmanship and jewellery-making skills of La Grande Maison, while paying homage to the women who inspire Jaeger-LeCoultre every day.
