It was just about three years ago that Jacob & Co. unveiled its first Astronomia watch — with a view of the sky on the wrist. Since then, the brand has evolved the Astronomia line time and again with sophisticated versions — but it is the newest model- being released at BaselWorld 2017 that steals the limelight. The Jacob & Co. Astronomia Solar watch is a vision of the solar system in ultimate, constantly rotating, beauty.
Main Features of the Jacob & Co. Astronomia Solar Watch
Brace yourselves, because this is a bit technical, but well worth the read. The newest Jacob & Co. Astronomia Solar watch, powered by a new movement, was two years in the making. It depicts eight planets on the dial: a three-dimensional hand-engraved globe that represents Earth, as well as Mercury, Venus, Mars,Jupiter, Saturn, Neptune and Uranus. There is also a 1.5-carat 288-faceted Jacob-Cut(R) citrine that depicts the sun.
What makes these planets vastly more interesting is the fact that they are constantly rotating, much like our solar system. We will bring you more on that momentarily. But first, back to what the watch offers in addition to the depiction of the solar system. The watch depicts: Hours and minutes on a subsidiary dial (sapphire); 60 seconds flying tourbillon bi-axial; 60 seconds rotating Earth and a bi-directional movement.
The Movement of the Jacob & Co. Astronomia Solar Watch
The 439-part bi-directional movement rotates clockwise to complete a full 360 degree revolution in just 10 minutes, while its alluring aventurine base rotates counter-clockwise 360 degrees in 10 minutes — ensuring the planets’ continual orbit. The Jacob & Co.caliber JCAM19 is equipped with 3 arms:
- The first arm holds the hour & minute dial made of sapphire, it rotates counter-clockwiseto ensure that 12 o’clock is always in the correct position, regardless of where the subdial is, thanks to a patented differential system.
- The second arm holds a two axes (10 min/60seconds) gravitational flying tourbillon decorated with a Jacob & Co. logo on its cage.
- The third arm holds an hand-engraved globe of the Earth rotating around its own axis in 60 seconds and completing one full revolution of the dial in 10 minutes. The bi-directional movement rotates clockwise to complete a full 360 degree revolution in just ten minutes, the aventurine base rotates in the opposite direction at exactly the same speed, creating an accelerated, stylized view of the solar system.The hand-engraved globe is part of an assembly that also houses the subsidiary hour and minute dial, as well as the one-minute flying tourbillon. The 44.5mm case size is a bit smaller than other Astronomia watches, but is the perfect presentation case for the caliber and its revolving mastery. The hand-wound calibre JCAM19 beats at a frequency of 4Hz (28,800 vibrations per hour), which is faster than any of the other Astronomia models.
