Overview
A vertical platform that turns in 10 minutes
The Jacob & Co. Astronomia Solar Constellations, reference AS300.40.AP.AK.A, in an 18-carat rose gold case with sapphire side panes, 45.5 mm across and 21 mm high. It has an openworked titanium hour and minute dial, on a blue alligator leather strap with a tang buckle.
The platform base on this version is aventurine, and each of its seven cabochon-cut planets is a named stone, from white granite for Mercury to lapis lazuli for Neptune.
A vertical platform rises from the dial and makes a full turn every 10 minutes. Jacob & Co. says this constant motion drives every function and indication of the movement. The base beneath the platform turns counterclockwise, also in 10 minutes.
Hand-wound calibre JCAM19 has 447 components and a 48-hour power reserve. A flying tourbillon hangs at the end of one satellite arm and turns in one minute. Carried by the platform, it gains a second axis with a 10-minute period. The hour and minute dial sits on another arm. Jacob & Co. describes a patented differential that turns the dial against the platform at the same speed, so it stays upright and readable. A magnesium Earth globe turns in 60 seconds.
