Jacob & Co: The New York Jeweller Pushing the Boundaries of Fine Jewellery and Watchmaking

In the world of ultra-luxury jewellery and watchmaking, Jacob & Co occupies a position of singular technical audacity. The New York house — founded by Jacob Arabo in 1986 and built into one of the most technically extraordinary and most visually spectacular luxury brands in the world — produces jewellery and watches of such extraordinary complexity and such unapologetic magnificence that they exist in a category of their own: objects of such ambition and such craft intensity that they challenge the very definition of what a watch or a piece of jewellery can be.

In 2026, as the appetite for the most extreme expressions of luxury craft continues to grow among the world’s most successful collectors, Jacob & Co’s position at the frontier of what is technically possible in fine jewellery and haute horlogerie has never been more clearly established.

The Jacob & Co Philosophy

Jacob Arabo founded his jewellery atelier on Fifth Avenue in New York in 1986 with a creative philosophy that has guided every decision the house has made since: that the finest jewellery and the finest watches should be the most extraordinary objects that human craft can produce — that the limits of technical possibility should be not merely approached but exceeded, and that the visual magnificence of the result should reflect the extraordinary effort that created it.

This philosophy — which prioritises technical ambition and visual impact over the restraint and the understatement that characterise many of the great traditional jewellery and watchmaking houses — has attracted a clientele of extraordinary cultural visibility and extraordinary financial means, from hip hop’s most successful artists to Middle Eastern royalty and the global business elite who value the most spectacular expressions of luxury craft.

The Astronomia

The Jacob & Co Astronomia is the most technically extraordinary watch in the world. The three-dimensional tourbillon movement — which rotates on multiple axes, displays the time through orbital hands and incorporates a miniature representation of the solar system in its architecture — is a feat of watchmaking complexity so extreme that it challenges the fundamental concept of what a watch is and what it can do.

The Astronomia’s architecture — which eliminates the conventional watch dial entirely in favour of a three-dimensional display of extraordinary visual drama — creates a wristwatch of such spectacular character that it functions simultaneously as a precision timepiece and as a wearable sculpture. The versions produced in diamonds, in coloured gemstones and in the extraordinary materials that Jacob & Co’s creative team develops for special commissions represent some of the most extraordinary wearable objects ever created.

The Billionaire Watch

The Jacob & Co Billionaire — a watch encrusted with hundreds of carats of emerald-cut diamonds in a setting of extraordinary complexity — represents the house at its most spectacularly magnificent. The watch’s combination of a technically accomplished movement with an exterior of such diamond density that the mechanism beneath is virtually invisible from casual observation creates an object of such visual impact that it has become a cultural reference point for the extreme end of luxury.

The Billionaire series — which has been produced in multiple variations including the Billionaire Timeless Treasure, with diamonds of extraordinary quality and extraordinary size — commands prices that place them among the most expensive watches ever created and a collector following of unusual intensity and unusual financial commitment.

The Fine Jewellery

Jacob & Co’s fine jewellery — which applies the house’s philosophy of extraordinary technical ambition and extraordinary visual impact to earrings, necklaces, bracelets and rings of exceptional gemstone quality — provides the most direct expression of Jacob Arabo’s founding vision. The diamond pieces, the coloured gemstone collections and the extraordinary one-of-a-kind commissions that the house produces for its most important clients represent fine jewellery at its most technically accomplished and its most visually magnificent.

The house’s relationships with the world’s finest diamond and coloured gemstone dealers — developed across nearly four decades of production — give Jacob & Co access to stones of exceptional quality and exceptional rarity that the most ambitious pieces require.

The Celebrity Connection

Jacob & Co’s relationship with the entertainment industry — which began with Jay-Z’s adoption of the brand in the early 2000s and has extended to virtually every significant figure in hip hop, R&B and the broader entertainment world — has been both a commercial driver and a cultural statement of extraordinary power. The brand’s visibility on the wrists and necks of the world’s most photographed performers has created a cultural currency that transcends the luxury jewellery market and connects the house to a global audience of aspiration and admiration.

The Bugatti Collaboration

Jacob & Co’s collaboration with Bugatti — which produced the Bugatti Chiron Tourbillon watch, a mechanical masterpiece that incorporates a working replica of the Chiron’s W16 engine in its movement — represents the most extraordinary single watchmaking achievement in the house’s history and one of the most extraordinary objects in the history of luxury. The watch’s miniature engine, which replicates the reciprocating motion of the Chiron’s pistons through a mechanism of extraordinary complexity, creates a timepiece of such technical ambition that it has been recognised as a landmark in both watchmaking and automotive history.

The Verdict

Jacob & Co in 2026 is the ultra-luxury brand for the collector who wants the most technically audacious and the most visually spectacular objects that human craft can produce. Its combination of the Astronomia’s watchmaking revolution, the Billionaire’s diamond magnificence and the Bugatti collaboration’s engineering achievement makes it one of the most extraordinary and most uncompromising propositions in the global ultra-luxury market.
