Jacob & Co. Astronomia
Jacob Arabo came up with a winner with the original design of his Astronomia watch. The Astronomia tourbillon was a watch to be worn with pride, a watch that stands out on the wrist and a watch that requires – how can I put this – an affirmed personality.
There are so many things that set the Jacob & Co. Astronomia watches apart from the crowd. First of all, there is the case, which by the standards of other watches is not much of a case at all, at least as far as its precious metal content. Because the Astronomia is all about transparency and showing off the inner workings of that triple axis tourbillon to the full. As a result, the precious metal has more of a structural role, for the lugs, case back and a slender bezel to act as a frame for the huge dome of sapphire crystal. The Jacob & Co. Astronomia has no dial in the conventional sense. There is the opposite side of the case back, which carries a variety of finishes from mirror polished to starry skies. You will not find a crown on the side of the Astronomia case, either. The watch is wound and set using two bows on the back. All this is to ensure that there is no distraction from the magic that is happening beneath that sapphire crystal dome.
The key to the attraction of the Jacob & Co. Astronomia tourbillon is the hand-wound movement that beats beneath the sapphire crystal. It is a triple axis gravitational tourbillon that consists of four individual arms rotating about a central axis. In the innumerable watches in the Jacob & Co. Astronomia collection there are two constants on each of these four arms: the triple axis tourbillon movement itself and the hour and minute subdial. The other arms may house a miniature representation of the Earth, precious stones representing the sun, moon or numerous other planets, or even an astronaut.
The tourbillon itself deserves closer inspection, since there are few other such triple axis tourbillon watches on the market. The tourbillon has three axes of rotation (hence the triple axis name): the first is the usual 60 second rotation about its own central axis that governs the minutes, the second is the axis of its arm, around which it rotates every two and a half minutes, and the third is the central axis, about which it rotates every 10 minutes.
The name of the Jacob & Co. Astronomia, of course, is a celestial reference and the four arms and different axes of rotation allow for different interpretations of our cosmos, where the display of the time itself almost takes on a secondary role. At their simplest expression, two of the arms house a magnesium globe at one end and a special Jacob cut diamond at the opposite extreme representing the sun. Others use the diamond and other precious stones to depict other planets in the solar system, in the Jacob & Co. Astronomia solar watches.
These highly complicated mechanical watches would not be true Jacob & Co. watches, however, were it not for the magic touch of the renowned jeweler Jacob & Co. All the different Astronomia tourbillon models are available in a bewildering choice of gem-set versions in which the baguette diamond plays a starring role alongside the famous Jacob cut diamond. The baguette diamonds may be set on the lugs, the entire case band, the entire background of the watch.
But aside from the gold and diamonds, there is another typically Jacob side to the Astronomia in the form of playful models inspired by the world of gambling and animals. We see Jacob & Co. Astronomia tourbillons with the names “Gambler” and “Casino”, both of which feature and roulette wheel as the base (and in the case of the latter watch, it even works), as well as “Dragon”, “Octopus” and “Spider”.
Here are just a few examples of the many watches in the Jacob & Co. Astronomia tourbillon collection.
