The Mystery Rose Gold And Diamond

a gold and silver watch


Mystery watches, timepieces where the time indications seem to be floating over the dial, are part of the grand history of watchmaking, going back more than 100 years. It should come as no surprise high watchmaking and diamond jewelry house Jacob & Co. has brought the mystery back with a contemporary high watchmaking and high jewelry twist.

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

Powering this incredible timepiece are two of Jacob & Co.'s iconic triple-axis tourbillons, placed back-to-back. The first axis makes a full revolution in 60 seconds, while the second and third axes make a full revolution in two minutes. The power reserve for this high watchmaking movement is 60 hours.


The two mystery disks turn to indicate the time, rotating around the twin triple axis tourbillons, linked by a single differential, set into the center of the watch. This 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. has placed its two incredible triple axis tourbillon movements in the center of the watch, where they turn on three axes: the first axis in 60 seconds, and the second and third axes in two minutes.
