A New Diamond Language from JACOB & CO.

Founded in New York and long established as a reference point for extreme high jewellery watchmaking, JACOB & CO. has built its identity on an ambition to move beyond existing conventions. The Billionaire collection has consistently represented the pinnacle of that vision — a platform where gem-setting and watchmaking meet without compromise. With the Billionaire Double Tourbillon Angel Cut, the House introduces not just a new watch, but an entirely new diamond cut developed and patented in-house.

The Angel Cut was conceived to bring a fresh expression of light to a rectangular stone. Through distinctive geometry and precisely engineered facets, it alters the way light behaves across the diamond’s surface, producing a brilliance described as continuous, balanced, and alive. That this cut was developed entirely within the House — rather than sourced from an external cutter — underlines the level of vertical integration JACOB & CO. now operates at. For collectors in the GCC, where extraordinary high jewellery timepieces command serious attention, this proprietary innovation carries genuine weight.

The Architecture of the Case and Dial

The 54 x 41 mm case is crafted in white gold and set with 98 Angel Cut diamonds totalling 51.13 carats. Rather than treating the dial as a separate surface, JACOB & CO. extended the same architectural logic inward, combining additional Angel Cut stones with baguette-cut diamonds to create an uninterrupted field of light from bezel to movement. In total, the watch carries 298 diamonds totalling nearly 79 carats — a figure that reflects both the ambition of the design and the precision required to execute it at this scale.

The pairing of the Angel Cut’s rectangular format with baguette-cut stones is a deliberate compositional choice. The two geometries share a linear character, which means the transition between them reads as a coherent whole rather than a contrast. The result is a dial architecture where every surface contributes to the same optical effect, rather than competing for attention. For a collector accustomed to exceptional high jewellery watches, this cohesion is as technically demanding as it is visually distinctive.

The JCAM50 Caliber and Its Twin Tourbillons

Beneath the diamond surface, the JCAM50 hand-wound caliber provides the mechanical foundation. Built from 460 components, the movement features two flying tourbillons placed at 12 and 6 o’clock — a symmetrical arrangement that mirrors the balanced geometry of the setting above it. The flying tourbillon configuration, in which the tourbillon cage appears to float without a top bridge, is among the most demanding constructions in fine watchmaking, and deploying two within a single movement speaks to the caliber’s engineering ambition.

The positioning of the twin regulators at opposing poles of the dial creates a visual axis that reinforces the watch’s architectural symmetry. This relationship between movement layout and gem-setting layout is not incidental — it defines the watch as a unified object rather than a case housing a separate movement. That level of design integration places the Billionaire Double Tourbillon Angel Cut in conversation with the broader standards of haute horlogerie, regardless of the brand’s unconventional identity within the industry.

Why It Matters

Limited to 18 pieces, the Billionaire Double Tourbillon Angel Cut is a document of what JACOB & CO. is capable of when gem-setting innovation and mechanical watchmaking are developed in parallel rather than in sequence. For GCC collectors who regard exceptional timepieces as both an artistic and technical statement, a proprietary diamond cut paired with a 460-component twin-tourbillon movement is a combination that demands serious consideration.
