A Focused Look

• The Billionaire Double Tourbillon Angel Cut features a 54 x 40 white gold case fully set with black diamonds.
• A total of 296 Angel-cut black diamonds are distributed across the case, dial, and clasp, totalling 77.86 carats.
• The dial is invisibly set with 168 Angel-cut black diamonds (10.2 ct.); the clasp carries a further 30 (16.36 ct.).
• The Angel Cut is a proprietary, patented geometry developed by JACOB & CO to maximise light return even in the darkest stones.
• The movement is a hand-wound, skeleton double tourbillon, fully visible through the open-worked architecture.

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 is 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 build a timepiece defined by depth, contrast, and controlled 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 works within those constraints, coaxing contrast and surface animation from stones that would otherwise read as 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, which conceals all metal prongs beneath the stone surface, produces an unbroken field of black articulated only by the 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. The open-worked dial keeps the movement in full view, a counterpoint to the dense black diamond setting that surrounds it. The mechanical interior and the jewelled exterior are conceived as a single composition: a horological instrument and a wearable sculpture occupying the same object.

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. 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, one that signals a clear directional shift. By deploying the Angel Cut in black diamond form, the house extends a proprietary innovation into new aesthetic territory, territory that speaks directly to collectors who value rarity, exclusivity, and the convergence of haute horlogerie and high jewellery. In 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.
