Jacob & Co. Unveils Proprietary Angel Cut Diamond Architecture in the Billionaire Double Tourbillon Masterpiece

In a defining moment that bridges technical gemology with haute horlogerie, Jacob & Co. has introduced the Angel Cut—a proprietary diamond cutting technique developed entirely in-house and protected by patent. This innovation arrives as the distinguished manufacture celebrates its 40th anniversary, marking four decades of uncompromising vision in the realm of high jewelry watchmaking.

A Diamond Cut Born From Legacy and Precision

The Angel Cut represents more than technical achievement. Named in tribute to Angela, the wife of founder Jacob Arabo, the cut is defined by a precise configuration of 37 facets—a numerical homage to their 37 years of marriage. This structural composition was refined over a two-year period, addressing one of gemology's enduring challenges: maximizing light return and optical performance in rectangular diamonds while minimizing material loss during the cutting process.

Traditional brilliant cuts, while renowned for their fire and brilliance, often require significant sacrifice of rough material. The Angel Cut departs from this convention through the integration of a distinctive lozenge-shaped table and a stepped rectangular outline, creating a controlled interplay of light that reduces extinction zones and produces a continuous, dimensional glow across the diamond's surface. The result is a gemstone architecture that unites visual drama with technical efficiency.

The Billionaire Double Tourbillon Angel Cut: A Wearable Constellation

The inaugural platform for this patented diamond innovation is the Billionaire Double Tourbillon Angel Cut, a timepiece that transforms the wrist into a luminous statement of contemporary luxury. Crafted from 18K white gold, the substantial case measures 54mm x 41mm, creating a commanding presence framed by an uninterrupted cascade of light.

The case architecture is illuminated by 98 Angel Cut diamonds totaling approximately 51.13 carats, each stone precisely oriented to maximize the proprietary facet structure's optical advantages. This exterior brilliance extends seamlessly to the dial, where an additional 88 Angel Cut diamonds are invisibly set into the 18K white gold surface, creating a pavé field that appears to float above the mechanical elements beneath.

Framing the twin tourbillon apertures are 80 baguette-cut white diamonds, their linear geometry offering a contrasting rhythm to the dimensional sparkle of the Angel Cut stones. In total, the timepiece incorporates nearly 300 white diamonds with a combined weight of approximately 79 carats—a concentration of gemological artistry rarely encountered in horological design.

Mechanical Symmetry Beneath a Pavé Sky

Beyond its gemological envelope, the Billionaire Double Tourbillon Angel Cut houses the exclusive hand-wound JCAM50 caliber, a 460-component movement engineered to deliver both visual theatre and mechanical precision. Two one-minute flying tourbillons are positioned symmetrically at 12 and 6 o'clock, their rotation visible through apertures carved into the diamond-set dial.

This dual-tourbillon configuration serves both aesthetic and functional purposes. The symmetrical placement creates visual balance within the fully pavéd environment while contributing to the movement's chronometric stability. The 72-hour power reserve ensures extended autonomy, while water resistance to 30 meters provides practical wearability despite the timepiece's ornamental intensity.

The watch is secured to the wrist via a blue alligator leather strap, its rich hue offering a chromatic counterpoint to the white gold and diamond brilliance. The strap integrates a diamond-set 18K white gold deployment buckle, ensuring that every visible element maintains the composition's unwavering commitment to luxury materiality.

An Edition Reserved for the Exceptional Few

Reflecting its position at the apex of Jacob & Co.'s high jewelry and haute horlogerie portfolio, the Billionaire Double Tourbillon Angel Cut is restricted to a worldwide edition of just 18 pieces. This limitation underscores the timepiece's status not merely as a watch, but as a collector's artifact—a convergence of patented gemological innovation, mechanical complexity, and sculptural design.

For four decades, Jacob & Co. has pursued a vision of watchmaking where traditional boundaries between jewelry and horology dissolve. The Angel Cut stands as both culmination and new beginning—a proprietary technology that redefines how light interacts with stone, and how exceptional timepieces can simultaneously honor personal legacy and advance technical possibility.

In an era where true innovation is increasingly rare, the introduction of a patented diamond cut represents a singular achievement, positioning Jacob & Co. at the vanguard of contemporary luxury's most ambitious frontier.
