Where Engineering and Gem-Setting Converge

JACOB & CO has built its reputation on timepieces that refuse to separate mechanical ambition from jewellery artistry. Founded in New York and now with a strong following across the GCC — where collectors in Dubai, Riyadh, and Doha have long gravitated toward its most theatrical creations — the brand consistently pushes both horological and lapidary craft to their outer limits. The Mystery Tourbillon is a clear expression of that philosophy, presenting a complication of genuine technical depth within a setting of extraordinary gemstone work.

The watch houses a twin, central, flying, triple-axis tourbillon — a regulating mechanism that rotates simultaneously across three distinct axes. This configuration demands exceptional precision in both design and finishing, as the slightest imbalance across any of the rotation planes will affect timekeeping. Presenting such a mechanism as a visible centrepiece, rather than concealing it beneath a dial, reflects a deliberate choice to make the movement itself the primary spectacle.

The Spectacle of 550 Baguette-Cut Sapphires

The case and dial of the Mystery Tourbillon are invisibly set with 550 baguette-cut multicoloured sapphires, totalling 45 carats. Invisible setting — a technique in which no metal prongs or bezel edges are visible between stones — is among the most labour-intensive processes in high jewellery. Achieving it with baguette-cut sapphires across a curved case requires each stone to be individually calibrated and fitted into a concealed rail system, a task that can account for hundreds of hours of a single craftsperson’s work. The result is an unbroken field of colour that shifts with every movement of the wrist, with no interruption between stones.

The multicoloured sapphire palette adds another layer of visual complexity. Rather than a single-colour gradation, the arrangement creates a play of light across a spectrum, so that each angle of observation reveals a different chromatic composition. This quality makes the piece particularly well-suited to the strong natural light and interior lighting conditions common across Gulf environments, where the sapphires’ optical properties are most fully animated.

Mysterious Time Display

The hour and minute indication is described as mysterious — a display in which the hands appear to float without any visible connection to a central arbor or conventional movement architecture. Two diamond markers serve as the sole reference points for reading the time. This approach prioritises visual continuity with the gem-setting, ensuring the timekeeping function integrates seamlessly with the overall aesthetic rather than interrupting it.

Scarcity as a Design Statement

The Mystery Tourbillon exists as two unique pieces. At this level of production, the watch crosses from limited edition into the territory of bespoke high jewellery — each example effectively a singular object rather than a numbered variant of a larger series. The 50mm case is offered in white or rose gold, allowing each of the two pieces to carry a distinct character while sharing the same architectural and mechanical DNA. For collectors who approach watchmaking as a convergence of wearable sculpture and horological achievement, this scarcity is itself a meaningful specification.

The full details of the Mystery Tourbillon are presented on the JACOB & CO official website, where the brand’s broader high jewellery and haute horlogerie offerings can be explored alongside this piece.

Why It Matters

For GCC collectors who value both mechanical integrity and gem-set artistry, the Mystery Tourbillon represents a rare convergence of the two disciplines at the highest level. With only two pieces in existence, it stands as one of the most exclusive timepieces JACOB & CO has produced — a reference point for the direction the brand continues to pursue at the intersection of movement engineering and jewellery craft.
