Hands-on Jacobs Astronomical Solar
Jacob & Co. solar system watch gets the sun.
Jacob & Co. Astronomia Solar is the latest version of the Astronomia tourbillon. The tourbillon made its debut at Baselworld in 2014 and is one of the most watched watches. The exhibition, and the fact that a company famous for high-end jewelry and watches created such a complicated mechanical device that is visually eye-catching has caused many people to turn their eyes and their tongues tremble. Of course, this is not the first high mechanical complexity of Jacob & Co., but from a design point of view, this is undoubtedly the most amazing, and it does have the collective imagination of the watchmaking world. Many companies have adopted this truly top, minimalist, large or large watch design,
Since the introduction of the first model, the design has continued to evolve. One of the most interesting models is the Astronomia Sky, which includes real-time display of stars and star maps (we conducted hands-on experiments earlier this year), and we are also very happy to have Jacob & Co. founder Jacob Jacobo and watchmaker Luca Soprano, who participated in the watch design studio Studio 7h38 (the movement and watch partner of Jacob & Co.), talked about “Astronomy” in the office with a video.
The latest version of astronomy is astronomy solar. Solar is different from other astronomical watches in many ways. The first thing you may notice is that the center bracket has three arms instead of four. The time is visible on a dial (the dial is mounted on a differential gear system, which ensures that 12:00 is always placed on the top for easy reading of the time), while the tourbillon is located on the second support arm. The earth representing the earth is on the third arm. The center of the carrier is a 1.5 carat citrine with 288 facets.
Like other Astronomia watches, Astronomia Solar is not an astronomical complex function in the usual sense, that is, it does not mean that it accurately reflects the movement of celestial bodies. For example, the miniature earth does not rotate around its axis once every 24 hours. Instead, Jacob & Co. chose to create a visually more dynamic experience, the real purpose is to capture the irrational excitement of watching the night sky, not what you might say, more the simplicity of “spherical music” And rational pleasure. Of course, the astronomical sky has accurate real-time indications of stars, but the fidelity of actual celestial dynamics has always been an exception rather than a rule in astronomical watches.
The earth’s rotation speed is fast enough that no rotation can be seen: it rotates every 60 seconds, and now the vehicle system rotates every 10 minutes, which is twice the previous model of the vehicle system (one rotation takes 20 minutes). . The earth in the astronomical sky makes a vertical axis of rotation once every 24 hours, which is the most accurate astronomical digital watch for astronomy. Like other models, the earth is enamel-titanium alloy and is hand-carved.
The two-axis flying tourbillon rotates around its central axis once per minute; technically, this is a two-axis tourbillon thanks to the ten-minute rotation of the carrier arm.
The base (the background of the carrier system) is Aventurine with stylized representations of all the planets in the solar system (only eight; Jacob & Co. replica insisted on the International Astronomical Union’s controversial decision to downgrade the first nine planets), so sorry, Pluto Fans).
The upper and lower strings of the movement are carried out by two keys on the bottom cover, with recessed hinged labels. Like early astronomical models, the sides of the case are inlaid with sapphire panels.
This is not the smallest astronomer; the original astronomy is 50 mm in diameter and the crystal height is 25 mm. In contrast, the astronomical sky is relatively slim, measuring 44.5mm x 21mm. Obviously, the focus of these watches is not to be a companion for daily travel, but to be fascinating displays. However, many people may find the 44.5mm version to be worn by astronomers, while the 50mm version is not.
The movement diameter of the JCAM19 movement is 16.50mm x 34.55mm, including the height of the carriage arm and its parts (not including the garnet impact that drops to 11.70mm), and the frequency is 28,800 vph, which is higher than any previous astronomer All are high. model. Since the design is more complicated than other astronomical watches (especially the counter-rotating Aventurine background), the number of parts is higher than any other astronomical watch: 447 components (excluding gems).
Like all Jacob & Co.’s high complexity, the basic design theme can have many possible variations. This is as superb as the modern watchmaking industry, but behind the hustle and bustle is hidden a lot of hardcore and serious clockwork-like all replica Astronomia watches, reliable performance and reasonable chronographs are obtained through the movement. Therefore, it rotates on the central axis. Many of the mobile elements are clever tricks.
