The Mystery Tourbillon by Jacob & Co for Jewelry Watch
Mystery watches, timepieces where the hands 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 new Mystery Tourbillon presents a world first -- two linked central triple axis tourbillons placed back to back in the center of the dial -- in a gem-set package. 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 and turning 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 red ruby 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.).
Features simplified: Two triple-axis tourbillons in the center of the dial; mystery time display; minute and hour disks set with hexagonal diamonds
