The Chopard L’Heure du Diamant Round reference 10A178-5101 brings the warmth of rose gold to the collection’s most intimate scale. At 26 mm, the 18-carat rose gold case is set with 22 prong-set brilliant-cut diamonds across the bezel and lugs — approximately 2.20 carats — with a natural mother-of-pearl dial and a single briolette diamond crown. The integrated rose gold bracelet in a bricked-link design completes a watch conceived as much as a jewel as a timepiece.
Design & Craftsmanship
The rose gold tone of reference 10A178-5101 gives the diamonds a warmer, more intimate glow compared to its white gold counterpart. The bricked bracelet flows seamlessly from the case, making the watch feel like a single sculpted object.
Movement
A manually wound movement with approximately 30 hours of power reserve. Water resistant to 30 metres.
