L'Heure du Diamant in Ethical 18-Carat White Gold

L’Heure du Diamant

Precious time, perfectly set

For several decades, the jewellery watches in the L'Heure du Diamant collection have symbolised the dual nature of Chopard's exceptional expertise: contemporary high-precision watchmaking and artistic jewellery design. The collection is now enhanced by a new 26 mm-diameter model in ethical 18-carat white gold, with a textured mother-of-pearl dial surrounded by diamonds featuring Chopard’s signature crown-setting technique. Its bark-type bracelet stems from goldsmithing work mastered exclusively by the Manufacture. It is powered by the Chopard 10.01-C mechanical manual-winding movement, one of the most compact sizes and thicknesses on the market. Stirring strong emotions, this talisman is a testament to technique, form and material uniting in perfect alchemy.

A jewel that tells the time: the dual nature of Chopard's expertise

Combining watchmaking expertise with Haute Joaillerie excellence, dainty diamond-set watches lie at the heart of the history and identity of the Scheufele family, who have served as guardians of Chopard's development for generations. The L'Heure du Diamant collection epitomises this duality, masterfully mingling contemporary vision and vintage allure; hard materials and soft shapes; exquisite aesthetics and precision.

At the crossroads of these skills, L'Heure du Diamant is a collection inspired by jewellery timepieces fashioned by the creative freedom infusing Chopard’s workshops during the 1960s and 1970s. Today, these timepieces have become veritable collector items, coveted by only the most stylish. Combined with colourful ornamental stone dials, these watchmaking jewels are the result of over a century of technical and aesthetic supremacy, as Caroline and Karl-Friedrich Scheufele's grandfather was already dubbed the ‘Master of the jewel-watch’ in the early 20^th century. This historical heritage was acknowledged in 2013, when the Grand Prix d’Horlogerie de Genève awarded its “Jewellery Watch Prize” to a L'Heure du Diamant timepiece in rose gold entirely paved with diamonds.

Imbued with harmony and symmetry, L'Heure du Diamant models come in a variety of round, oval, cushion, octagonal or heart-shaped cases, making the collection a veritable beacon of creativity. In 2025, Chopard has chosen the treasures of its L'Heure du Diamant collection to adorn its Maison Ambassador Bella Hadid in a new campaign, widely acclaimed across watch, jewellery and fashion circles.

Noble aesthetics: a majestic dial encircled by a diamond crown

The distinctive characteristic of L'Heure du Diamant timepieces is a bezel entirely set with generously sized diamonds, gracefully framing a dial sculpted from the rich colours and poetic symbolism of ornamental stones. While the collection regularly draws upon the charms of opal, onyx, malachite and turquoise, this new round 26 mm-diameter model features a dial in rare textured mother-of-pearl – an exquisitely feminine, pure and iridescent material gathered from the heart of seashells. It is encircled by more than two carats of brilliant-cut diamonds, whose radiance is enhanced by a gem-setting technique unique to Chopard: the crown setting, which exalts the beauty of each stone by allowing light to flood through with exceptional brilliance. Designed with V-shaped prongs, this process, originally devised by Karl Scheufele supports the arrangement of the diamonds like invisible lacework. Thus released from the constraints of opaque metal, the mineral purity of diamonds can shine through fully, as the timeless grace of L'Heure du Diamant jewellery embodies fragments of eternity.

The bark-type bracelet: a goldsmith's masterpiece

Crafted in ethical 18-carat white gold, this L'Heure du Diamant timepiece is paired with a bark-type bracelet featuring an ergonomic, silky texture achieved by unique expertise. In reference to the plant-life theme, extremely fine veining gives the bracelet a lifelike appearance, as it endows the gold with an incomparably supple, light touch. This bracelet gently nestled against the skin does not cling to fabrics, instead following the wearer's every move thanks to the entirely hand-crafted goldsmithing technique perfected by the Scheufele family in the 1960s. 

A high-precision mechanism: the Chopard 10.01-C movement

Beating at the heart of the watch, the Chopard 10.01-C mechanical manual-winding movement driving the hours and minutes has a 45-hour power reserve. Measuring just 15.70 millimetres in diameter and 2.90 millimetres in thickness, this in-house calibre introduced in 2024 is one of the smallest and thinnest in the world, making it suitable for dainty jewellery watches. It was entirely developed and produced within the Maison’s workshops in Fleurier, Switzerland, revealing the technical genius and constant quest for innovation cultivated by Chopard.
