The JCAM10 is Jacob & Co.'s signature Astronomia caliber, featuring a revolutionary three-dimensional architecture with a central vertical axis carrying four rotating satellites. The gravitational triple-axis tourbillon rotates on multiple axes to counteract gravity's effects on timekeeping accuracy. The movement showcases a 1ct spherical Jacob-cut diamond representing the moon and a hand-engraved titanium Earth globe that rotates independently. With 365 components, this caliber exemplifies the brand's mastery of haute horlogerie complications.
