The Caviar collection performs as the ultimate platform to exhibit Jacob & Co's unrivalled gem-setting mastery. Its perfectly round case and traditionally styled lugs create a recognizable atmosphere, the ideal stage from which every detail of this haute joaillerie masterpiece can well and truly stand out. From every angle and down to their finest details, every piece in the Caviar collection serves as a testament to the remarkable engineering, planning, gem-cutting and gem-setting know-how that Jacob & Co uniquely possesses.

The Caviar Tourbillon Arlequino Baguettes is a high jewelry masterpiece, with a case, bezel, crown, dial and movement bridges all fully set with multi-colored sapphires and white diamonds that sparkle in their natural beauty. In its every color configuration, the Caviar shall serve as a most resolute testament to Jacob & Co's dedication to, and expertise in the discipline of ultra-high-end jewelry.

Until the creation of the exclusive JCBM05 caliber, no movement could have hoped to keep pace with the intense brilliance of the Caviar's exterior. Matching the intricate gem-setting with the beautiful complication of a one-minute flying tourbillon, the JCBM05 has bridges specifically designed to be able to accommodate gem setting.

The tourbillon was designed to offset the effect of gravity on a watch movement. The tourbillon used in the Caviar is the flying variety, meaning that it is supported on only one side, which is far more difficult than a traditional tourbillon. The tourbillon has long been considered the king of complications, with its spinning and turning movement. Only the best companies can accomplish this feat of high watchmaking.

The hand-wound caliber, which may be further admired through a sapphire crystal caseback, with its plates adorned with white diamonds, complements its one-minute flying tourbillon with a balance wheel with gold timing screw, anti-shock system and 100-hour power reserve. Composed of 169 parts, the movement drives a two-hand dial display at a frequency of 21,600vph.

Having started out as a jewelry company, Jacob & Co. has been working in the gemstone trade for more than thirty years. As a result, the brand's jewelers know where to find the best gemstones.

With unique pieces like the Caviar Flying Tourbillon Arlequino, getting the right color of the baguette-cut multi-colored sapphires to mix with the white diamonds is incredibly important. It can take up to three years to find the right stones, with exactly the right color.

The sapphire is September's birthstone and blue is the most popular shade of sapphires, and they also come in blue, violet, green, yellow, pink, purple, and intermediate hues - just about all of which are used in the Arlequino.

When it comes to setting, Jacob & Co. works with the very best in the world. The diamonds in this timepiece are invisibly set, side by side, which hides the metalwork underneath. The diamonds are set into the gold from underneath, making the surface smooth and the diamonds appear to be floating on the case. The result is mesmerizing and magical.

One look at the Caviar Flying Tourbillon Arlequino and you know how rare and special it is.

The 47mm 18K white gold dial, case, buckle, and lugs are invisibly set with the highest-quality baguette-cut multi-colored sapphires in varying hues and white baguette-cut diamonds to achieve the Full effect. The flying tourbillon is visible in an aperture at six o'clock, and the white diamond-set rear of the manual winding movement is visible through the exhibition case back.

The Jacob & Co. Caviar Flying Tourbillon Arlequino is a tour de force in both high jewelry and high watchmaking, taking both to an extreme never seen before.
