What Sets the Billionaire Ashoka Apart in Other Luxury Diamond Watches

Highly coveted among elite collectors and high jewelry connoisseurs, the Billionaire Ashoka stands apart through its use of exceptionally rare Ashoka-cut diamonds, celebrated for their elongated shape and remarkable brilliance. Combined with Jacob & Co.’s signature skeletonized movement and extravagant gemstone architecture, the watch creates an unmatched display of luxury and exclusivity. Its extraordinary 189-carat diamond composition and Pièce Unique status make it one of the most prestigious Jacob & Co creations ever produced for the ultra-luxury watch market.

Design and Craftsmanship

The watch features a sculpted 53 x 40 mm 18K white gold case set with 38 Ashoka-cut white diamonds totaling approximately 36.86 carats, complemented by a central white rose-cut diamond of approximately 0.35 carats. The integrated bracelet is entirely adorned with 252 Ashoka-cut white diamonds totaling approximately 151.22 carats, creating a breathtaking seamless flow of brilliance across the wrist. The openworked architecture exposes the skeletonized movement beneath the anti-reflective sapphire crystal, while the exclusive blued skeletonized hands provide elegant contrast against the fully diamond-set composition.

Movement and Performance

At the heart of the Billionaire Ashoka lies the Jacob & Co. Skeleton Caliber JCAM23, a hand-wound mechanical movement composed of 167 components. Operating at 21,600 vibrations per hour, the movement delivers approximately 72 hours of power reserve while powering a one-minute tourbillon designed to enhance chronometric precision and visual sophistication. The skeletonized architecture maximizes transparency and allows light to interact beautifully with the surrounding Ashoka-cut diamonds.
