Overview
Two tourbillons joined back to back
The Jacob & Co. Mystery Tourbillon, reference SN800.40.BD.UC.A, in an 18-carat rose gold case, 50 mm across and 25 mm high. Its 18-carat rose gold hour and minute rings are each set with 119 yellow sapphires and 1 white diamond, on a blue alligator leather strap with an 18-carat rose gold folding clasp. This version is a pièce unique.
The case carries 192 hexagon-cut white diamonds. Yellow sapphires also set the inner ring and the clasp, the 12 hour markers are white diamonds, and the two hands are set with white diamonds.
Jacob & Co. describes the watch as a double tribute. One half is to mystery clocks, which it credits to the 19th-century watchmaker Jean-Eugène Robert-Houdin. The other is to the tourbillon. Hours and minutes are shown on two concentric rings rather than on a conventional dial.
Hand-wound calibre JCAM32 has 430 components and a 50-hour power reserve. Its two tourbillons are coupled back to back, with a differential linking them, and sit in a deep pit at the centre of the watch. The tourbillon is flying, held on a single anchoring point, and turns on three axes with no upper bridge, in 60, 120 and 120 seconds.
