Join Dong Ho Che Tac as we explore every detail of this exceptional masterpiece and its staggering price.
1. The Origin Story of the World’s Most Expensive Jacob
The origin of the Billionaire Timeless Treasure stems from Jacob Arabo’s long-standing passion for diamonds, especially rare colored stones. From his early days as a jeweler, Arabo prioritized the purity and hue of each gem, shaping his design philosophy.
In 2016, Jacob & Co. launched the original Billionaire watch, featuring a skeletonized design and large white diamonds. Timeless Treasure builds on that spirit but pushes material standards even further. For the first time, natural yellow diamonds become the main design element, requiring a completely reengineered watch structure to ensure consistent color, clarity, and size across all stones.
2. Closer Look at the World’s Most Expensive Jacob & Co Watch
Every aspect of the Billionaire Timeless Treasure—from its case to its movement—demonstrates unparalleled complexity and refinement. Let’s break down the three features that elevate this model to iconic status.
2.1 Nearly 500 Rare, Natural Yellow Diamonds
This timepiece features 482 natural yellow diamonds, all rated from IF to VVS in clarity and categorized as Fancy Yellow or Fancy Intense Yellow—two of the rarest and most valuable diamond grades. Each stone is large enough to be Asscher-cut with 57 perfectly aligned facets, optimizing brilliance.
The original rough diamond weight totaled 880 carats. Only 216.9 carats remained after precision cutting and selection. Of these, 57 baguette-cut stones were specifically crafted for the movement. An additional 76 tsavorite stones surround the dial, adding balance and contrast.
Every step—selection, cutting, certification, and setting—was carried out by hand in Geneva. It took more than three and a half years and a team of seasoned gemologists and artisans to ensure perfect harmony in shape, clarity, and tone.

The JCAM39 operates at 3Hz and offers a 72-hour power reserve—a high-performance metric for handcrafted skeleton watches. A 1-minute tourbillon is located at 6 o’clock, counteracting gravity to improve accuracy. This f
2.3 18K Gold Dial, Hands, Strap, and Clasp
The inner dial ring is made from 18K gold and set with 76 tsavorites in brilliant and emerald cuts (~3.59 ct). The hour and minute hands are Jacob & Co’s proprietary design, skeletonized and deep green in color to blend with the dial’s openness.
The strap and folding clasp are also crafted from solid 18K gold, serving as a base for 378 Asscher-cut yellow diamonds (~159.62 ct). The case holds an additional 46 Asscher-cut diamonds and a rose-cut yellow diamond on the crown, bringing the total gold weight to 297 grams. The entire structure appears seamless—no visible screws—for a unified aesthetic across dial, strap, and clasp.
