In 2026, the Jaeger-LeCoultre Reverso One 'Hibiscus Rosa' Q3292325 was unveiled as part of the La Vallée des Merveilles collection. This exquisite timepiece features an 18-carat pink gold case and bracelet adorned with a remarkable total of 1,029 diamonds. Notably, the watch is limited to just 20 pieces, making it a truly exclusive item.

The reversible case, measuring 40 by 20 mm and 9.09 mm in thickness, is embellished with 645 diamonds, while the pink gold bracelet is further decorated with 384 diamonds. Overall, the gems weigh around 8.07 carats and require meticulous craftsmanship, taking approximately 160 hours to set them. The setting techniques include both grain and snow settings, the latter utilizing diamonds of various sizes arranged in a seemingly random manner. The watch also boasts a water resistance of up to 30 meters.

On one side, the dial features white mother-of-pearl, accented by black transferred Floral numerals and pink gold Dauphine hands, while Art Deco-style brackets elegantly outline the time display. A diamond graces the crown, extending the watch's jewelry theme. The reverse showcases a stunning enamel scene of an Akialoa above a red hibiscus, nestled amid tropical foliage in rich red, blue, and green hues. The pistil of the flower is masterfully created with gold leaf techniques and layered translucent enamel. The bird and foliage are rendered in grand feu champlevé enamel, with pink gold sections filled with thin layers of enamel firing at extreme temperatures. Snow-set diamonds frame the backdrop, enhancing the beauty of the enamel art. Powering the watch is the manually wound Jaeger-LeCoultre calibre 846, precisely designed for the Reverso One's case, offering a power reserve of about 50 hours at a frequency of 21,600 vibrations per hour.
