Jacob & Co. unveils the Billionaire Double Tourbillon, an extraordinary luxury watch featuring 749 diamonds.

The Billionaire Double Tourbillon is a limited edition of 18 pieces in white gold set with 144.7 carats of emerald-cut white diamonds. A total of 749 diamonds are set in an invisible setting (a method of setting diamonds without visible prongs) that covers the dial, case, bracelet and clasp of this special model.

Jacob & Co. "Billionaire Double Tourbillon"

The Billionaire Double Tourbillon marks a number of firsts for the Billionaire collection. It's the first to feature a full dial paved with 168 baguette-cut diamonds in a "brickwall" pattern. It's also the first to offer both a detachable bracelet entirely set with emerald-cut diamonds and a blue alligator leather strap with a diamond-set buckle. It's also the first to feature a movement other than a skeleton tourbillon.

The Caliber JCAM50 is a double flying tourbillon movement with an exceptionally high level of finish, and its skeletonized design is clearly visible from the back. The Billionaire II, featuring 424 diamonds totaling 161 carats, features a tourbillon movement set with 57 emerald-cut diamonds. These two tourbillons combine chronometer information via a differential system and transmit it to the central hand, providing the Billionaire Double Tourbillon with extremely precise timekeeping. The Caliber JCAM50 offers a power reserve of approximately 72 hours.

Double Tourbillon Movement

　The Art Deco bridges, built on a geometric skeleton structure, echo the brickwall dial pattern. The movement contains a pair of barrels, each closely connected to a tourbillon. The two mechanisms are connected beneath the movement's filigree structure to form a flying tourbillon.

Alternating setting pattern known as "brick wall"

The white gold dial of the Billionaire Double Tourbillon is paved with 168 emerald-cut diamonds, arranged in an alternating "brickwall" pattern, and features two large circular openings to accommodate the tourbillon cage.

Curved case

　The Billionaire Double Tourbillon comes in a 54 x 40 mm white gold case that blends seamlessly with the diamond-set bracelet, creating a seemingly continuous beginning and end—one of the Billionaire's key features.

　The case has been specially treated to feature the largest jewels in the entire construction: 76 diamonds (total weight 38.08 carats) and a 1-carat rose-cut crown. The thickness of the watch has been reduced to just 11 mm.

Detachable bracelet and strap

　The Billionaire collection features special elements designed for fit and comfort. The timepiece is crafted entirely from white gold, and the structure required to house the 749 diamonds weighs a massive 355 grams. The Billionaire Double Tourbillon's curved case and sapphire crystals on both sides create a high-jewelry finish with elegant lines and a beautiful silhouette.

　For the first time, Jacob & Co. has designed a detachable bracelet. With the proper tools and care, the diamond and gold elements can be removed from the case. The Billionaire II Double Tourbillon is delivered on an alternative strap made of blue alligator leather with a diamond-set folding clasp. The Billionaire Double Tourbillon offers two personalities and two styles of luxury.
