The Astronomia watches from Jacob & Co. are astronomical first
and foremost by their price. And while the mechanical ingenuity
of their design is evident, more than anything they are a
poetic metaphor for the cosmic ballet, an incredaible, spinning
show enclosed beneath the watch’s crystal.

Above the celestial
dial, which accomplishes a full rotation in one sidereal year –
the time it takes the Earth to make one full rotation around the
sun in relation to the fixed stars – four satellites rotate together
in 20 minutes. The three-dimensional representation of the
terrestrial globe in lacquered titanium also rotates on its own
axis, as does that of the moon, represented by a cut diamond.
The third satellite carries the dial with the hours and minutes.
Driving it is a triple-axis gravitational tourbillon that completes
its rotation around the first axis in 60 seconds, around the
second in five minutes and right around the dial in 20 minutes.
