A Darkened Vision of Brilliance

JACOB & CO has long operated at the intersection of watchmaking and high jewellery, and the Billionaire Double Tourbillon Angel Cut represents one of the most concentrated expressions of that philosophy. Where earlier Billionaire pieces celebrated light through colourless or coloured stones, this new expression inverts the language entirely — choosing black diamonds to create a timepiece defined by depth, contrast, and a controlled kind of drama. It is a deliberate shift in register, from radiance to intensity.

The watch is constructed on a 54 x 40 white gold case, and every visible surface is dedicated to the Angel Cut. The result is a monolithic object that absorbs the eye rather than reflecting it back. For collectors who favour bold, statement-level pieces — a sensibility that resonates strongly in the GCC market — this is a watch conceived in precisely that spirit. You can explore the full range of JACOB & CO creations on the official JACOB & CO website.

The Angel Cut: Proprietary Geometry, Extraordinary Purpose

The Angel Cut is not a borrowed technique. It is a patented, proprietary diamond geometry developed exclusively by JACOB & CO, engineered to amplify the optical properties of any stone it is applied to — including black diamonds, which present a far greater challenge than their colourless counterparts. Black diamonds do not transmit light; they absorb it. The Angel Cut is designed to work within those constraints, coaxing contrast and surface animation from stones that would otherwise appear flat.

On the Billionaire Double Tourbillon, this geometry is applied at scale. The case alone carries 98 Angel-cut black diamonds weighing 51.2 carats. The dial is invisibly set with a further 168 stones at 10.2 carats, and the clasp contributes 30 more at 16.36 carats. Invisible setting — a technique that conceals all metal prongs beneath the stone surface — amplifies the seamless, all-diamond aesthetic. The cumulative effect is a unified field of black, articulated only by the subtle geometry of each cut facet.

The Double Tourbillon Movement

Beneath the jewelled exterior, the Billionaire Double Tourbillon Angel Cut houses a hand-wound, skeleton movement built around a double tourbillon complication. The skeleton architecture means the movement is visible through the open-worked dial — a counterpoint to the dense black diamond setting that surrounds it. The interplay between the mechanical interior and the jewelled exterior is central to the piece’s identity: it is simultaneously a horological instrument and a wearable sculpture.

The double tourbillon places JACOB & CO firmly within the upper register of complications, alongside houses that have built reputations across decades of technical achievement. For GCC collectors drawn to both mechanical mastery and jewellery-level finishing, the combination is particularly compelling — a single object that satisfies both instincts without compromise. You can view the official presentation in the official JACOB & CO video.

Why It Matters

The Billionaire Double Tourbillon Angel Cut is a significant statement from JACOB & CO — not simply for its technical specification, but for the direction it signals. By deploying the Angel Cut in black diamond form, the house extends a proprietary innovation into a new aesthetic territory, one that speaks directly to collectors who value rarity, exclusivity, and the rare convergence of haute horlogerie and high jewellery. In markets such as Dubai, Riyadh, and Doha, where appetite for exceptional one-of-a-kind timepieces remains among the strongest in the world, a piece of this nature commands serious attention.
