Billionaire Timeless Treasure is an unprecedented achievement in the history of high jewelry watchmaking. Never before has there been a timepiece so lavishly set, with so many high quality and large yellow diamonds. Never before has the gathering of such gemstones been as long, patient and resolute in its quest for quality and color consistence. Never before have said stones been cut at such a high level of complexity as the Asscher cut in such large quantities for a single piece. Three and a half years in the making, this Billionaire timepiece of 425 Asscher-cut, Fancy Yellow and Fancy Intense Yellow diamonds is an undertaking of Olympus-like proportions, and a divine result.
Impossibly plentiful
The joint effort required by the manufacturing of Billionaire Timeless Treasure has gathered ten staff to search, sort and cut the gems. Fifteen more to craft the yellow gold lattice structure, set it and encase the movement. Under the expert and uncompromising eye of Seraina Wicht, head of gemology watch production at Jacob & Co., 880 carats of the rarest and most opulent rough yellow diamonds, some of them reaching 2.50 ct, have contributed to this masterpiece.
Impossibly rare
Yellow diamonds are nothing like white diamonds. A 10,000 to 1 occurrence, they're infinitely more expensive. Especially so in the past twelve months. Especially at the size Billionaire Timeless Treasure requires. To reach the final 216.89 carats, Jacob & Co. started with 880 carats of rough diamonds. Not a single gem was rejected because of price. Only because its color and clarity wouldn't make the cut.
Impossibly demanding
Crafting Billionaire Timeless Treasure was not only a game of patience, but also a game of skills and color. In the overall scheme of this new type of Billionaire, each gem has a designated place. The larger ones are meant for the case, which comprises 46 of them for a total of 55.15 ct. The first rows of the 159 ct-bracelet also demand hefty gems, with their individual size diminishing in perfectly regular increments as they near the clasp. But the gems are not placed according to their original size. Only color matters here. So several large stones have been cut with massive waste of matter.
Impossibly colorful
Since it was impossible to maintain color intensity with yellow diamonds of those dimensions, Jacob & Co. used one of its favorite gems, one that has now become a signature of the brand's highest-end creations : tsavorite. This rare green garnet provides Billionaire Timeless Treasure with extra life, extra relief and unrivaled gem composition. 76 of them have been selected, emerald-cut and kite-cut, to surround calibre JCAM39. The skeleton movement Jacob & Co. uses in all its Billionaires is regulated by a tourbillon so thin, so fine it might go unnoticed at first sight. The nature of all Billionaires is to combine the demands of high jewelry with those of high watchmaking. Which is why the extremely fine skeleton is enhanced with 57 baguette-cut yellow diamonds.
Signature craft
The immaculate appearance and design of the Billionaires also lies in the special setting technique Jacob & Co. has been using, its signature way to attach the gems onto an underlying gold lattice : the very rare and demanding invisible setting. As of February 2023, a total of 21 Billionaire timepieces had been crafted and all of them sold either directly to their owners or to the most high-end watch retailers on the planet, with the exception of one. And then Billionaire Timeless Treasure was introduced, setting a new bar for Jacob & Co., although one the brand will undoubtedly strive to exceed.
