The Jacob & Co. Billionaire Double Tourbillon Angel Cut

A Considered Look

• The Billionaire Double Tourbillon Angel Cut is presented in three distinct expressions: white, yellow, and black diamonds.
• The Angel Cut is a proprietary, patented diamond geometry developed by JACOB & CO and named after Angela Arabov.
• Diamond surfaces cover the entire case and dial across all three versions.
• The movement is a hand-wound, skeletonized double flying tourbillon.
• JACOB & CO positions the three expressions not as variations but as three independent defining statements.

A Vision Cast in Three Dimensions

JACOB & CO has long occupied a singular position in high horology. The New York maison fuses gem-setting at the highest level with mechanical ambition that few watchmakers attempt. The Billionaire Double Tourbillon Angel Cut is one of the most concentrated expressions of that philosophy: a timepiece where the architecture of the stone and the architecture of the movement are conceived as a single, indivisible whole. For collectors across Dubai, Riyadh, and Doha who seek watches that communicate both technical authority and visual drama, this is a piece conceived with precisely that sensibility in mind.

The release arrives as three distinct expressions rather than a single reference with optional dial colours. JACOB & CO is deliberate on this point: these are not variations of one icon but three defining statements, each realised through a different diamond, white, yellow, and black, that transforms how the piece interacts with light, shadow, and its wearer. That conceptual rigour elevates the collection beyond a commercial exercise into something closer to an authored creative position.

The brand’s approach to ultra-luxury gem-set watchmaking has consistently pushed the boundary of what a diamond-covered case can mean mechanically. Rather than treating stones as surface decoration applied over a conventional watch architecture, JACOB & CO integrates the gem-setting into the structural identity of the piece itself. This philosophy finds its fullest expression in the Billionaire Double Tourbillon Angel Cut.

The Angel Cut: Geometry with a Name

At the core of the collection’s identity is the Angel Cut, a proprietary and patented diamond geometry that belongs exclusively to JACOB & CO. Named after Angela Arabov, the cut carries personal provenance that grounds its technical innovation in human meaning. A patented cut in the watch and jewellery world signals not merely an aesthetic choice but a defensible and original contribution to the craft of gem-cutting itself. The Angel Cut’s geometry shapes how each diamond refracts and returns light, giving the three expressions of the Billionaire a visual behaviour that conventional brilliant or baguette cuts cannot replicate.

Across white, yellow, and black diamonds, the Angel Cut produces three entirely different readings of the same object. White diamonds maximise brilliance and contrast against the skeletonized movement beneath. Yellow diamonds introduce warmth and a depth of colour that shifts the piece’s emotional register entirely. Black diamonds, with their light-absorbing opacity, produce a version that reads as a study in form rather than fire; closer to sculpture than jewellery. Together, the three constitute a complete conversation about what a diamond can do when the geometry is purpose-built rather than inherited from tradition.

The Double Flying Tourbillon Within

A continuous, uninterrupted field of Angel Cut stones envelops case and dial alike. A hand-wound, skeletonized double flying tourbillon provides both the motive force and the visual centrepiece of the watch. The skeletonization is not incidental; it is essential to the concept. By removing material from the movement bridges and plates, the tourbillon cages are rendered fully visible through the diamond surface above, producing a layered composition in which mechanical precision and gem-set brilliance occupy the same plane of vision simultaneously.

Two independent tourbillon regulators operating without a conventional top bridge represent a significant investment in both design and fabrication. The hand-wound specification reinforces the artisanal character of the movement: there is no rotor to obscure the view, and the act of winding connects the wearer directly to the energy that drives the complication. That combination places the Billionaire Double Tourbillon Angel Cut in a narrow category of timepieces where gem-setting and mechanical depth are genuinely equal partners. Explore the full range of JACOB & CO creations at the official JACOB & CO website, where all three Angel Cut expressions are presented in detail.

Achieving continuity across a three-dimensional case form, covering curves, edges, and the transition between case flank and dial, without visible interruption requires stone-selection calibrated to within fractions of a millimetre and hand-setting carried out at a pace that prioritises alignment over speed. This level of execution separates a genuinely integrated jewellery watch from one that is simply heavily set, and it reinforces the coherence of the overall vision JACOB & CO has pursued across the collection.

Why It Matters

For GCC collectors and jewellery-watch enthusiasts, the Billionaire Double Tourbillon Angel Cut sets a clear benchmark in the convergence of high gem-setting and serious mechanical watchmaking. The proprietary Angel Cut geometry, the skeletonized double flying tourbillon, and the three-expression presentation make this a reference point in contemporary ultra-luxury horology.
