THE MYSTERY TOURBILLON 44MM

Amethyst

The Mystery Tourbillon 44MM is a horological statement of exceptional sophistication. Its highly elaborate movement is covered in and surrounded by a dizzying number of gems. It sums up the very nature of Jacob & Co., which is the combination of high jewelry, high watchmaking and relentless innovation. The Mystery Tourbillon 44MM is a double tribute to great achievements of high watchmaking. One is Mystery Clocks. First invented by 19th century watchmaker and illusionist Jean-Eugène Robert-Houdin, they amazed the crowds with their intriguing and apparently impossible mechanisms. Like them, The Mystery Tourbillon 44MM’s display is enigmatic. The other is the tourbillon itself. The Mystery Tourbillon 44MM is a contemporary, never-imagined take on the brand's flagship complication : its carriage spins 360° on three axes, at high speed, and is set with 3 different types of diamonds, including a 288-facet, Jacob-cut one. The sophistication of the gem-setting Jacob & Co. has applied on The Mystery Tourbillon 44MM is beyond measure. The 44-mm case and dial elements are drenched with over 545 gems of hexagon and baguette cut.

From a creative concept to design inspiration. To the first stroke of a pencil through hundreds of iterations. A timepiece like no other comes to life. The Mystery Tourbillon 44MM combines unheard-of levels of watchmaking and gem-setting sophistication, resulting in a mind-blowing creation.

Five years after releasing The Mystery Tourbillon in a diameter of 50 mm, Jacob & Co. decided to take on another challenge : to deliver the magic and puzzle of this incredible high jewelry, high complication watch in a smaller, more wearable format. To achieve that goal, to fit into a 44 mm-wide gold case, the original twin, flying, back-to-back, triple-axis tourbillon has evolved in both architecture and ornamentation. The most striking mechanical aspect of The Mystery Tourbillon 44MM is its tourbillon. It doesn't have an upper bridge, therefore it's a flying tourbillon. It's right in the middle of the watch, therefore it's a central tourbillon. Its carriage rotates on three different sets of gears, therefore it's a triple-axis tourbillon. The Mystery Tourbillon 44MM is a central, flying, triple-axis tourbillon. What's more, and for the first time, the tourbillon carriage is covered by a decorative structure set with a 288-facet, Jacob-cut diamond and 9 hexagon-cut white diamonds. This structure, shaped like a flower, spins along with the carriage. This tourbillon alternates between a flower and a technical design.

THE ROTATING RINGS

The mysterious part of The Mystery Tourbillon 44MM is that it doesn't have hands. Instead, hours and minutes are displayed on two concentric rings, lavishly set with overlapping gems. They tell time with a pair of pointers, made from a gem of different colors than the others.

THE CENTRAL, TRIPLE-AXIS FLYING TOURBILLON

There is no other tourbillon like The Mystery Tourbillon 44MM. It sits in a deep pit in the middle of the watch. It rotates on three axes and without an upper bridge. The rotation speeds for the axes are respectively 1, 2 and 2 minutes, which is incredibly fast for such a sophisticated construction.

PEAK GEM-SETTING

The 44-mm gold case of The Mystery Tourbillon 44MM is entirely set with gems. The invisible setting technique leaves no apparent gold and unites all the precious stones seamlessly. The caseband uses the hexagon cut, one of the rarest there is. The tourbillon carriage is set with a 0.4 ct Jacob-cut, 288-facet diamond, surrounded by 9 hexagon-cut diamonds. As for the ones sitting under the sapphire crystal, they're a rare variant of the baguette-cut, with arrow-like tips. They create a three-dimensional effect like shards of ice in a melting iceberg.

The Mystery Tourbillon 44MM manifests the best crafts and design ingenuity of Jacob & Co. It is a statement of absolute lavishness and exclusivity. Uniting the utmost level of both watchmaking and gem-setting makes it a timepiece that is, literally, without compare.
