Multicolor. The astronomical tourbillon baguette Arlequino‘s color range makes this watches unique. ⠀
The 281 rectangular-cut colored sapphires on the dial provide a colored background for the four satellite structures above. ⠀
A three-axis tourbillon, 288 faceted Jacobs cut diamonds, a time display and a magnesium globe make the dial rotate within 10 minutes, and sapphires of different colors are playing hide and seek.
The four arms of the astronomical tourbillon are equipped with a three-axis tourbillon chronograph mechanism, a blue lacquered magnesium alloy globe and a rose gold earth, which perfectly shows the Planet Earth, which is an exclusive Jacob-Cut® 1 carat diamond. A total of 288 faces, and then display the time. This four-arm assembly can complete the rotation around the center of the watch and the spectacular background in 20 minutes.
Another amazing feature of the astronomical tourbillon is how each pair of opposing arms perfectly calculates each other’s counterweight-a testament to the unparalleled material engineering and watch movement design. By applying equal weight to these opposing arms, when the movement occupies different directions in space, the shaft will be free from stress and increase the tension.
The tourbillon is considered the ultimate complication because it can rotate and rotate to counteract the influence of gravity on the accuracy of the movement. For the astronomy tourbillon baguette Arlequino, Jacob & Co. took the tourbillon one step forward, introducing other axes of tourbillon rotation. For the astronomical tourbillon Arlequino, the tourbillon is three-axis rotation-along two axes: one spins in 60 seconds, the second spins in 1 minute and 15 seconds, and the third spins in an amazing 5 minutes The inside rotates around the dial.
The basic dial is completely invisible, with 281 rectangular-cut multicolor sapphires (≈12.65ctw) set on it, which is the spectacular backdrop of the rotating satellite above. This makes the perfect combination of cutting and inlaying skills and ultra-high-end watchmaking technology, which is unique to Jacobs.
Since its establishment in 1986, Jacob & Co. has been at the forefront of using gemstones and has developed many special cutting and setting techniques. For the astronomy tourbillon, the brand developed 288 faceted Jacob cut diamonds. This special cut can only be done by a few gem cutters, and rough stones usually start with twice the size of a finished diamond. The facets must be very precise, so the diamond must be perfectly symmetrical and rounded. In the astronomical tourbillon, a diamond cut heavier than Jacobs spins automatically in 15 seconds.swiss watches
The globe is made of blue lacquered magnesium with rose gold continents to ensure weight consistency, because all four satellites must have exactly the same weight. The earth rotates in 30 seconds and travels on the dial for 10 minutes.
The case of the astronomical tourbillon has a diameter of 50 mm and a thickness of 25 mm, between the highest point of its specially curved front sapphire crystal and the lowest point of the case. Made of 18K rose gold or 18K white gold, each style is equipped with four sapphire crystal glass windows on the periphery of the case, allowing unobstructed viewing of the magnificent caliber and exquisite gems inlaid inside.
The time display sub-dial of the astronomical tourbillon is driven by an infinitesimal differential system. When it rotates with the four-arm platform of the movement, it always remains horizontal and clear and easy to read. The Roman numerals on the hollow dial are hand-engraved and painted with black varnish, while the hand-made hands are dark blue metallic. watch luxury
