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 black spinel and the dial is set with hexagonal, "overlapping" black spinel. The sophisticated and ground-breaking Mystery was more than one year in development.
