The $18 Million Watch Covered In Diamonds: Inside the Jacob & Co. Billionaire
In the world of luxury timepieces, there are expensive watches, and then there are statements that redefine the concept of wealth. The $18 million Jacob & Co. Billionaire watch falls firmly into the latter category—a timepiece so extravagant that it made headlines not just for its craftsmanship, but for the audacity of its owner and the sheer volume of diamonds it contains.
This is the story of the watch that became a cultural phenomenon.
The Billionaire Watch: A Diamond Masterpiece
The Jacob & Co. Billionaire watch was first unveiled in 2015 at Baselworld, one of the most prestigious watch and jewellery fairs in the world . From the moment it was revealed, it was clear that this was no ordinary timepiece. The tonneau-shaped 18K white-gold case and integrated bracelet were set with an astonishing 260 carats of emerald-cut diamonds, each individual gem weighing approximately 3 carats .
Jacob & Co. described the watch as a unique piece that “truly epitomizes the brand’s passion for breaking boundaries” . The skeletonized dial reveals a manual-wind tourbillon movement—a complex mechanical feature that counteracts the effects of gravity on the watch’s accuracy—while the ballet of light from 260 carats of diamonds illuminates its “exquisitely revealed heartbeat” .
The watch was a one-of-one design, not available to the general public, making it an exclusive treasure for a single buyer . Its original price tag? An eye-watering $18 million .
Floyd Mayweather: The Perfect Owner
In 2018, the Billionaire Watch found its match in Floyd Mayweather, the undefeated boxing champion known as much for his flamboyant lifestyle as his record in the ring . Mayweather purchased the watch from Japanese jeweler Tadashi Fukushima and immediately took to Instagram to show it off .
“This my new timepiece, it’s called ‘The Billionaire Watch,'” Mayweather informed his followers.”If you’ve never heard of it, just search for ‘Billionaire Watch’ online.” That’s $18 million on the price tag” .
The purchase was characteristic of Mayweather, who has a history of flaunting his wealth—despite having faced a $22.2 million IRS tax lien just a year earlier . He has worn the Billionaire Watch courtside, in private jets, and in selfies, treating it like a daily driver despite its museum-tier value . In doing so, he redefined what “everyday luxury” could mean and blurred the line between high jewellery and horology .
The Jewelry That Outshines the Watch
What makes the Billionaire Watch truly remarkable is that the diamonds are not merely an accent—they are the watch. The case and bracelet are custom-crafted in 18K white gold, and the 239 emerald-cut diamonds are all D color, IF clarity—the highest possible grades for diamond quality . Every individual stone weighs 3 carats, making the watch not just a timepiece but a wearable diamond collection .
The jewellery trade has taken note. Inspired by Mayweather’s purchase, jewellers in New York’s Diamond District now offer custom “bustdown” watches and iced-out replica builds using lab-grown emerald cuts, starting at around $20,000 for collectors chasing a similar aesthetic . The original, however, remains untouchable—a one-of-one masterpiece that has become part of horological history .
How Does It Compare to the World’s Most Expensive Watch?
While the $18 million Billionaire is extraordinary, it is not the most expensive watch ever created. That title belongs to the Graff Diamonds Hallucination, valued at $55 million . Unveiled in 2014, the Hallucination features 110 carats of rare, multi-coloured diamonds—including pink, blue, green, orange, and yellow—set into a platinum bracelet . It took a team of 30 specialists, including designers, gemologists, and craftsmen, over four and a half years to create .
However, the Hallucination remains in the possession of Graff founder Laurence Graff and is not for sale . In contrast, the Billionaire Watch was actually purchased and worn, making it perhaps the most valuable watch ever to be publicly flaunted.
The Legacy of teh Billionaire
The Jacob & Co. Billionaire Watch stands as a testament to the extremes of luxury culture. It represents the convergence of horological craftsmanship and high jewellery, wrapped in a package that is as much a statement of wealth as it is a functional timepiece.
For Mayweather, it was the ultimate flex. For Jacob & Co., it was a defining moment that cemented the brand’s reputation for audacious, boundary-breaking design. And for the rest of us, it remains a fascinating glimpse into a world where a watch can cost more than a mansion—and be worn to a basketball game.
