The ultimate testament to Jacob & Co's unmatched watchmaking and gem-setting experience, know-how and singular position is the Billionaire II. In the world of high jewelry horological masterpieces, the Billionaire has opened a parallel universe on its own where it exists in perfect solitude, unrivaled and untouched. A grand total of 177.11 carats of 325 emerald-cut and baguette-cut diamonds make up the case and bracelet of the Billionaire, encapsulating the Exclusive Jacob & Co JCAM09 skeletonized tourbillon caliber. Haut de gamme haute joaillerie meets cutting-edge haute horlogerie with the Billionaire II in era-defining ways.

The one-minute tourbillon of the Billionaire II is haute horlogerie's response to the high jewelry tour de force that surrounds it. With its black mirror polished upper cage - a finishing technique that requires immense patience and dexterity -, hand-bevelled and hand-polished edges and calculated operation, the tourbillon is the only complication to live up to the breathtaking visual experience of the diamond-set exterior.

The tourbillon encapsulates the balance wheel, hairspring, escape wheel and a number of other crucially important, superbly finished components. Its most careful assembly is followed by a painstaking fine-tuning process, allowing the Billionaire II to keep accurate time throughout its extended, 72-hour power reserve.

The sheer beauty of the tourbillon is complemented by a uniquely skeletonized movement and its magnificent architecture. Its plates have been extensively skeletonized to a point where the delicate movement is securely held in place by a web-like structure of thin bridges, all refined and decorated by hand. This maintains focus on the quality of surface treatments and their haute horlogerie quality of execution: the presence of watchmaking greatness that is to be appreciated, despite their exquisite environment.

Jacob & Co. is one of the few brands that has the legitimacy to create high and fine jewelry, as well as high-end watches.

The diamond and gemstones industry is a closed society, and it is really a relationship business. Sourcing the very best diamonds and gemstones depends on reputation and personal connections, and thankfully Jacob & Co. has solid, decades-long relationships.

As a result, Jacob & Co. has access to the very best sources of diamonds and gemstones from all over the world. Many of the gem-set timepieces, Billionaire, require meticulous care in the choosing of stones for quality, cut, clarity, and matching color. This can take many months or years, depending on the exact colors needed.

Jacob & Co. is also an expert in the setting of these stones, working with the very best gem setters in the industry. The diamonds in the Billionaire are set using the difficult and sophisticated "invisible setting" (meaning none of the supporting metal is visible).

This six-link bracelet is unlike any other ever created: every row in the Billionaire II's exquisite diamond-set bracelet comprises 6 links, all specially joined to allow for the flexibility, fit and feel required. The bracelet tapers from the lugless case all the way towards the diamond-set clasp, maintaining its six-link configuration and attaining the narrowing taper by careful and accurate planning that allows for the use of ever smaller sized diamonds. Gemmological expertise meets gem-setting know-how and world-class engineering.

The case of the Billionaire II measures 54 by 40 millimeters and is 11 millimeters thick between the top of its anti-reflective sapphire crystal and the lowest point of its case. Its case structure is crafted from 18K White Gold with a bezel, as well as lugs and case profiles fully set with emerald-cut diamonds. The case-back is sapphire crystal with an 18K White Gold frame.

The Billionaire II features no dial in the traditional sense: its skeletonized movement structure serves as the spectacular backdrop of its hands, whereas the hour markers are 12 baguette-cut white diamonds, set into the periphery of the flange frame. The hands are partially skeletonized and are treated with ruthenium, a rare transition metal belonging to the platinum group of the periodic table.
