Overview
A canvas for miniature craft
The Jacob & Co. Astronomia Art, reference AT100.30.AA.UD.B, in an 18-carat white gold case, 50 mm across and 25 mm high. Its titanium dial has a base of 18-carat gold hand-engraved with running stallions, on a black alligator strap with an 18-carat white gold deployant buckle.
Horses are among the subjects Jacob & Co. names for Astronomia Art. The case and caseback are 18-carat white gold, and the hands are blued.
Astronomia Art takes the Astronomia planetary system and uses it as a canvas for artistic craft. Jacob & Co. says the collection brings its watchmaking, high jewellery and artisan skills together, with decoration that ranges from hand-engraving to painted miniatures.
Hand-wound calibre JCAM18 has 365 components, 42 jewels and a 60-hour power reserve. A vertical platform with four arms makes a full revolution around the central axis in 10 minutes. Its triple-axis tourbillon turns in 60 seconds, 2.5 minutes and 10 minutes. The dial rotates on a patented differential gear system. A Jacob cut diamond and a blue lacquered magnesium globe each turn on themselves in 30 seconds.
