Mystery dials, timepieces where the indicators seem to be floating over the dial, are part of the grand history of watchmaking, going back about 200 years when it was first invented by a clockmaker who was also a practicing magician. Jacob & Co. has brought the mystery back with an innovative, contemporary high watchmaking and high jewelry twist.

The Mystery Tourbillon Arlequino combines high watchmaking; a world first with two linked central, back-to-back triple axis tourbillons; and high jewelry, as the case is invisibly set with baguette multicolored sapphires and the dial is set with hexagonal, multicolored sapphires and diamonds. The sophisticated and ground-breaking Mystery was more than one year in development.

Two triple-axis tourbillons positioned side-by-side in the center of the dial
present an inspiring mechanical and visual effect while powering the dial
and maintaining its accuracy. Most tourbillons are either set at the 12 or 6
o'clock position. Jacob & Co. is the first watchmaker to place two
triple-axis tourbillons in the center of the watch. The twin
complications turn simultaneously at 60 seconds for the first axis, and
two minutes for the second and third axis.

In hindsight it seems logical that the mystery dial was invented by a watchmaker who was also a practicing magician. The 200-year-old complication in which the watch hands appear to float inside the dial while keeping accurate time appears magical. Jacob & Co.'s interpretation of the mystery dial involves colored gems that cover two discs, one for the minute and one for the hour. A diamond on each gem-covered disc is used to indicate the time - secretly, mysteriously.

The case of the Mystery Tourbillon is invisibly set with baguette hexagonal diamonds and the dial is set with hexagonal, overlapping diamonds. The 50 mm white gold case and lugs and inner ring are invisibly set with 312 multicolored sapphires and diamonds (21.6 total carats). The minutes disc is invisibly set with 119 multicolored sapphires and one white diamond, which indicates the exact minute (9.5 total carats). The hours disc is invisibly set with 143 multicolored
sapphires and one white diamond, which indicates the hours (8.18 total carats).

The 50mm, 18K white gold case and lugs are completely paved with multicolored
sapphires, rubies and diamonds. There is no crown. Instead, the watch is set
and wound by two bows that lift out of the case back. The front and back of the
case are protected by anti-reflective sapphire crystals. Even with the
abundance of the gems the watch is water resistant to 30 meters.
