Chopard 13A386-1109 L’Heure du Diamant 30.5mm White Gold Black Onyx Diamond Watch

Chopard L’Heure du Diamant 13A386-1109 — Black Onyx and Diamonds in Perfect Harmony

The Drama of Darkness. The Brilliance of Diamonds.

The Chopard L’Heure du Diamant 13A386-1109 is a study in magnificent contrasts. The deep black onyx dial — one of the most dramatically beautiful surfaces in fine watchmaking — provides a stage upon which 4.64 carats of brilliant-cut diamonds perform at their absolute best. In Chopard’s 18K ethical white gold, this 30.5mm jewellery watch represents the Maison at its most theatrically elegant.

The Black Onyx Dial — Darkness as Luxury

Onyx is one of the most prized dial materials in high jewellery watchmaking. Its deep, lustrous black surface absorbs and refracts light simultaneously, creating a depth that no lacquer or enamel can replicate. Against this midnight canvas, the brilliant-cut diamond indexes achieve a brilliance that is extraordinary — each stone catching light and scattering it across the dial with every movement of the wrist. The contrast is both dramatic and refined, a balance only Chopard’s master gem-setters can achieve with such precision.

4.64 Carats of Brilliant-Cut Diamonds

Every diamond in the L’Heure du Diamant collection is individually selected for colour, clarity, and cut. Chopard’s in-house gem-setters work by hand to set each stone in the prong technique — the most demanding and most rewarding of all setting methods, allowing the maximum amount of light to enter and exit each diamond. The total of 4.64 carats transforms the bezel and case into a continuous cascade of brilliance.

18K Ethical White Gold — Responsible Excellence

The 30.5mm case, crown, and pin buckle are crafted entirely from Chopard’s 18K ethical white gold — 100% responsibly sourced since 2018 as part of the Maison’s Journey to Sustainable Luxury. The black alligator strap completes the composition with the deep, matte texture that only fine leather can provide, creating a watch that is extraordinary from every angle.

The Automatic Movement

Inside the 9.30mm-thin case, Chopard’s automatic movement — featuring 27 jewels — delivers Swiss precision in complete silence. Water resistant to 30 metres, sapphire crystal front glass, and the same quality standards applied across Chopard’s entire fine watchmaking range.
