The Mystery Tourbillon Black Spinel by Jacob & Co features a unique accomplishment in watchmaking, the only timepiece with two linked, central, back-to-back triple axis tourbillons - intertwined in a high jewelry accomplishment of the highest magnitude.
The 50-mm, 18K black gold case is invisibly set with baguette, hexagonal black spinels and the dial is set with hexagonal, "overlapping" black spinels. The sophisticated and ground-breaking Mystery is unique in a great many ways.
Powering this incredible timepiece are two Jacob & Co.'s iconic triple-axis tourbillons. They're placed back-to-back, forming but one single rotating ensemble. The pair rotates on a first axis making a full revolution in 60 second. It makes a full revolution on both the second and third axes in two minutes. Theirs is a unique positioning, as most tourbillons are either set at the twelve or six o'clock position.
This is the first time that Jacob & Co., or any other watchmaker for that matter, has placed two tourbillons in the center of the watch, and they're triple axis ones to boot.
The power reserve for this high watchmaking, complex and demanding movement is an astounding 60 hours
