There exists, at the highest echelon of watchmaking, a rarefied territory where timekeeping ceases to be the primary narrative and instead becomes a medium, a foundation upon which art, engineering, and extravagance converge. It is here, in this intersection of high jewellery and haute horlogerie, that Jacob & Co. has long established its dominion, dissolving the conventional boundaries that once separated gem setting from mechanical craft. The Jacob & Co Billionaire Double Tourbillon Angel Cut (Ref. BL140.30.BD.AC.ABALA), an 18-piece limited edition novelty is not merely an extension of this philosophy, it is its most articulate expression. At its core lies a fundamental question that has preoccupied gem setters and watchmakers alike for generations: can diamonds do more than decorate a watch? Can they, instead, define it?
The answer arrives in the form of the Angel Cut, a proprietary and patented diamond cut developed entirely in house. Rather than pursuing the familiar excess of additional facets, this innovation takes a more cerebral approach, refining geometry itself to achieve superior optical performance. Comprising 37 precisely engineered facets, the Angel Cut is defined by discipline rather than abundance, each surface calibrated to control the movement of light with remarkable precision.
At its centre rests a lozenge shaped table, enclosed within a stepped rectangular outline with cut corners, a geometry that subtly alters how light behaves within the stone. Instead of the fragmented brilliance associated with traditional cuts, the Angel Cut produces a composed luminosity, a continuous field of light characterised by reduced extinction and softened contrast. It is brilliance without aggression, radiance without chaos.
This measured optical performance is not merely aesthetic indulgence, it is a technical necessity. Within the confined and complex architecture of a gem set watch, light is often restricted, its pathways interrupted by metal, movement, and structure. The Angel Cut addresses this challenge with deliberate engineering, ensuring strong upward light return even in such constrained environments. It is, in essence, a cut designed specifically for horology, where beauty must coexist with precision and structural integrity.
To introduce such a cut, one requires a canvas of equal ambition. The Billionaire Double Tourbillon Angel Cut priced at $3.4 million obliges with emphatic confidence. Its 54mm case, crafted in 18K white gold, is transformed into an uninterrupted expanse of light through the setting of 98 Angel Cut diamonds totalling 51.13 carats. These are not supporting accents but commanding presences, stones of a scale typically reserved for singular jewellery pieces, here orchestrated into a cohesive whole.

The dial continues this architectural narrative, invisibly set with 88 Angel Cut diamonds alongside 80 baguette cut stones, collectively framing the twin tourbillons at 12 o’clock, and 6 o’clock with striking symmetry. In total, the watch carries 298 white diamonds, amounting to approximately 79 carats, a figure that transcends mere specification to become an assertion of intent. Its defining feature is the presence of two flying one minute tourbillons positioned at 12 and 6 o’clock, their mirrored placement reinforcing the watch’s overarching theme of symmetry.
These rotating regulators introduce motion into an otherwise still landscape of diamonds, creating a dynamic interplay between light and time. Every element, from the rhodium plated, blued, skeletonised hour, and minute hour tipped with Super LumiNova to the blue alligator strap secured by a diamond set white gold clasp, adheres to a singular vision. This is not ornamentation layered upon mechanics, but a complete integration of the two disciplines. Yet, beneath this luminous surface lies an equally formidable mechanical composition.
The JCAM50 manual winding calibre, comprising 460 components, powers the watch with a 72-hour reserve. The movement itself is revealed through a sapphire caseback, its skeletonised architecture offering a counterpoint to the density of the gem setting above. Here, transparency replaces brilliance, yet the sense of depth remains, reinforcing the duality that defines the piece. Even the self winding architecture, driven by a white gold micro rotor, operates with a near silent efficiency, ensuring that mechanical function does not disrupt the purity of the visual and tactile experience.
In the Billionaire Double Tourbillon Angel Cut, diamonds are no longer passive embellishments. They are structural, optical, and conceptual components, shaping not only the aesthetic but the very identity of the watch. It is this transformation that elevates the piece beyond extravagance. What emerges is not simply a watch, nor merely a jewel, but a synthesis of both, a meticulously composed statement in which light, geometry, and mechanical ingenuity coexist in absolute harmony, redefining what it means to wear time itself.
