You’re looking at Jacob & Co.’s new Astronomia Sky, a watch of singularly dazzling artistry.
The watch is an update and creative expansion on the brand’s Astronomia watch, which was itself staggeringly beautiful.
In comparison with its predecessors – Astronomia Tourbillon Baguette Watch (2015) and the Astronomia Tourbillon (2014), the Astronomia Sky is based on the gravitational and triple axis tourbillon movement of the Astronomia, but its functions and interpretation are very different.
It’s a completely never-before-seen display of time: a sidereal display; in other words, the watch shows the stars that are above you at that precise moment via an oval sky indicator rotating above the blue titanium celestial vault.
There is also the indication of the 24-hour Day and Night represented by the earth at the top of the movement and the indication of the second.
The moon is created using a 288-facet spherical diamond that reflects incoming light in a multitude of directions throughout its 60-second rotation around an independent axis.
The handprinted titanium Earth sphere also rotates every 60 seconds.
The tourbillon orbits the dial, alongside the other objects, every twenty minutes and a fourth arm offers the hours and minutes display.
This masterpiece provides two distinctive units of time: sidereal time and legal time (or solar time).
The watch is priced at $690,000 which is about N300 million.
