Design and Craftsmanship

The sculptural case measures 54 x 40 mm with a height of just 11 mm and is crafted entirely from 18K rose gold. An anti-reflective sapphire crystal and sapphire crystal caseback provide clear views of the intricate skeletonized movement.

The case is set with 76 emerald-cut natural, no-heat multicolored sapphires and accented by a white rose-cut diamond. The inner ring introduces 76 emerald-cut natural, no-heat rubies, adding a rich red contrast to the rainbow gemstone composition.

Gem-setting continues directly onto the movement bridges, while the 18K rose gold bracelet is decorated with 504 emerald-cut natural, no-heat multicolored sapphires. This extensive use of precious stones transforms the entire watch into a continuous piece of haute joaillerie.

Movement and Performance

At the heart of the Billionaire III Rainbow is the hand-wound Jacob & Co. JCAM39 skeleton caliber. Composed of 167 components, the openworked architecture exposes the movement's mechanical construction and allows the tourbillon to become a central part of the design.

The movement operates at 21,600 vibrations per hour (3 Hz) and delivers approximately 72 hours of power reserve. Its principal complication is a one-minute tourbillon, combining traditional haute horlogerie with the extravagant jewelry craftsmanship of the Billionaire collection.
