Jacob & Co. is back with an updated version of its stunning Astronomia Tourbillon. This time it has a domed sapphire case and a spinning 288-sided diamond representing the moon, which orbits around a hand-painted model of the earth. Most of the 236-component tourbillon movement is placed on a series of four arms that rotate around the entire dial each 20 minutes. With the moon and earth moving in celestial sequence, the timepiece promises an unequaled experience for the wearer.
Jacob & Co. says the Astronomia Tourbillon is 50mm wide and 25mm thick. The case is in 18k rose gold. Power reserve is said to be 48 hours.
Prices will range from $550K for the non-diamond version to north of $1 million for the Tourbillon Baguette version with diamonds (see below). The latter gets you 342 stones and 16 carats. But the bling shouldn't take away from what looks to be an amazing engineering achievement.
As for telling time, who knows. This watch is made for showmanship, not functionality.
