Overview
A solar system turning on a vertical platform
The Jacob & Co. Astronomia Solar Zodiac, reference AS910.30.BD.BD.A, in an 18-carat white gold case, 44 mm across and 21 mm high. It has a blue Zodiac dial and 382 baguette diamonds (≈12 ct) set on the base and lugs, on a blue alligator strap with an 18-carat white gold clasp. This version is limited to 18 pieces.
The case and case back are 18-carat white gold.
Jacob Arabo introduced the Astronomia concept in 2014, turning his interest in space into a watch. Here a vertical platform rises from the dial and makes a full turn every 10 minutes. Satellite arms carry the tourbillon, the time dial and the planets.
The hour and minute dial hangs at the end of one arm. As the platform turns, a differential system spins the dial the opposite way at the same speed, so the Zodiac signs stay upright and readable. Hand-wound calibre JCAM19 has 447 components and a 48-hour power reserve. Its flying tourbillon hangs from another arm and turns in 60 seconds; carried by the platform, it gains a second axis with a 10-minute period. An Earth globe turns in 60 seconds.
