Jacob & Co. Supernova Twin Central Tourbillons

The Jacob & Co. Supernova Twin Central Tourbillons watch combines high watchmaking, a world first with two linked central 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 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.

The minute disk is set with 119 White Diamonds (≈ 6.80 ct.) and one ruby (≈ 0.18ct.) to indicate the exact minute. The hour disk is also with 119 White Diamonds (≈ 7.93ct.) and one red ruby (≈ 0.28ct.) to show the hours. The 50mm 18K white gold case features a special domed sapphire crystal with anti-reflective treatment to show off the diamonds and the tourbillon, and the bezel inner ring is also set with gems — 12 Blue Sapphires (≈ 1.49ct.) and 108 White Diamonds (≈ 4.56ct.).
