Entrepreneur Karim Haddad spotted wearing a Jacob & Co

Dubai entrepreneur Karim Haddad was recently photographed wearing what is almost certainly the most structurally audacious wristwatch in current production: a piece unique Jacob & Co Bugatti Chiron Tourbillon, reference BU210.80.AM.UA.BBRUA, housed in a 44.4 mm case machined entirely from blue sapphire crystal. The sighting, set against the backdrop of Dubai's hypercar culture, feels entirely appropriate.

The Jacob & Co Bugatti Chiron Tourbillon is built around the manufacture calibre JCAM37, a hand-wound movement conceived as a horological homage to Bugatti's 8.0-litre W16 engine. Sixteen miniature cylinders are arranged in the characteristic W formation and actually animate via the mainspring's power, their pistons rising and falling in sequence — a kinetic display that serves no timekeeping function but communicates the brief with absolute clarity. A flying tourbillon regulates the movement, while power reserve sits at approximately 60 hours. The watch displays hours and minutes on two lateral subdials, deliberately subordinate to the engine spectacle at centre stage.

What elevates the BU210.80.AM.UA.BBRUA beyond the standard Chiron Tourbillon references — which already use titanium, rose gold, or carbon — is the sapphire case itself. Milling a structurally sound 44.4 mm case from corundum demands tolerances and tooling that few workshops in the world can execute. Sapphire is nine on the Mohs hardness scale, second only to diamond, making it catastrophically brittle under the wrong cutting conditions. The blue tint echoes the signature Bugatti Atlantic Blue finish, and in this piece unique configuration, it was produced as a bespoke commission rather than a catalogue offering.

Jacob & Co's collaboration with Bugatti formalised an existing relationship between two brands that share an unapologetically maximalist philosophy. Every confirmed Bugatti Chiron owner is eligible to commission a matching Chiron Tourbillon, with personalisation options tied directly to their car's specification — colour, trim, even VIN references have been incorporated into past pieces. Karim Haddad, a prominent figure in Dubai's entrepreneurial circles, fits squarely within that ownership profile.

At a retail price of $1,500,000, the Jacob & Co Bugatti Chiron Tourbillon in blue sapphire occupies a stratum where grey-market comparisons become largely academic. Piece unique commissions of this nature rarely trade publicly; when they do, provenance and spectacle command a significant premium over the already extraordinary list price.
