Looking for a unique timepiece that combines superb Swiss craftsmanship with horological brilliance, choose the Jacob and Co. Astronomia Solar Watch. A visual effect of the timepiece keeping every element in constant motion, all beating from an oscillator in the center of the three-axis tourbillon, showing the celestial world and an orbital display of hours and minutes. The brand is known for some of the more striking and bold timepieces on the market as well as some of the most expensive.
Taking a closer look at this extraordinary timepiece, the case design is rather ordinary, in 44.5mm 18k rose gold, filled with sapphire, allowing you to admire the brilliance of the movement inside. At 21mm thick, it looks chunky, but with a three-dimensional movement and a domed sapphire crystal, there’s no other option. This makes the watch very visible on your wrist and for others to notice. There is no visible crown on the watch, and setting the time and winding the movement is done using two folded 18k rose gold “bows” on the back of the case. What really stands out about this timepiece, however, is not the back, but the refined and elegant dial.
The exposed movement is open on the dial for everyone to see. The movement itself is made of three separate arms, one leading to the sub-dial showing the time, the second to the flying tourbillon and the third to the earth. Each blue hour and minute hand is designed to be very large and the time is very clear, contrasting with the skeletonized sub-dial in 18k rose gold.
The tourbillon bears the best Jacob & Co. logo on the bridges and rotates on two axes. You might be surprised that this Astronomia Solar Watch is a double axis tourbillon. The movement is rotated horizontally every 60 seconds and vertically every 10 minutes. The globe, crafted in rose gold and blue lacquer, rotates every 60 seconds, around the dial every 10 minutes, and the entire movement rotates clockwise every 10 minutes. The aventurine base is highly decorated to resemble the night sky and reflect the solar system in the timepiece.
The Astronomia Solar Watch by Jacob & Co. is breathtaking, with a large 1.5-carat citrine in the center of the dial, cut to represent the sun, and then set with three other gemstones: amethyst, garnet and smoky quartz to represent the other planets. If that alone wasn’t spectacular enough, the functional design lets these planets rotate with the movement, depicting a miniature solar system on your wrist. Equipped with 444 components, the in-house movement JCAM19 is unique because it is mainly made of titanium. This choice was made because of the large number of rotating parts and a way to lighten the load on the mainspring was found. The tourbillon beating at 4 Hz has a power reserve of 48 hours and is finished with beautiful sandblasted beveled bridges,
The Jacob & Co. Astronomia Solar Watch is a limited edition timepiece that truly puts the world on your wrist.
