ASTRONOMIA REGULATOR

Blue

Regulators date back to the 19th century manufacturing workshops, where dozens of workers gathered in the same space. They required a single reference time to regulate their work, hence the word Regulator. To optimize time reading, each of their indications were split into 3 distinct locations on the dial. The 43-mm case is fitted with large panes of sapphire. In a world first, the 3D, rotating movement makes one full turn in 60 seconds. It has a separate hours and minutes display. The ring-shaped seconds dial spins counterclockwise in one minute. With Astronomia Regulator, Jacob & Co. offers a ground-breaking take on the Regulator, transforming a watchmaking classic with one of its signature twists.

From a creative concept to design inspiration. To the first stroke of a pencil through hundreds of iterations. A timepiece like no other comes to life. With incredible speed and perfect readability, Astronomia Regulator introduces the Regulator to the 3rd dimension, and the 21st century.

Astronomia Regulator profits from Jacob & Co. experience in rotating, vertical, tourbillon movements, shaped by Astronomia Tourbillon. Its rotation speed was initially set at 20 minutes. In 2023, Jacob & Co. released Astronomia Revolution, whose rotation speed was one full turn per minute. Astronomia Regulator's caliber JCAM56 builds up on the experience of the Astronomia Revolution. It has a rotation speed of 60 seconds and carries three arms. One is a double-axis flying tourbillon. The other two arms are dedicated to the time display. The blue and translucent ring tells the seconds by spinning counter-clockwise in 60 seconds. One minute per 360-degree rotation requires a tremendous amount of energy flowing through a very delicate movement. To regulate that massive flow, Jacob & Co. added a patented constant force device. It provides the watch with a steady source of energy, and helps it be more accurate.

With a height of 13.75 mm, caliber JCAM56 is the slimmest Astronomia-type movement Jacob & Co. has ever designed, an accomplishment given its vertical nature. It features a total of 552 components, revolutionizes the régulateur display and adds "Inspired by the Impossible" horological performance.

ONE-MINUTE ROTATING MOVEMENT

Like all Astronomias, caliber JCAM56 is a vertical, three-dimensional, rotating platform. It is the fastest in all the Astronomia collection. It completes one full spin every 60 seconds. The entire movement can be used as a seconds indicator.

THE REGULATOR DISPLAY

Astronomia Regulator has one separate sub-dial for minutes, and another for the hours. Attached to the platform, they also spin in one minute. If left alone, they would end up upside down. Astronomia Regulator uses a differential system to keep them upright all the time.

THE FLOATING SECONDS RING

From the movement's base, a long golden hand sticks out. It points to a large, domed and translucent ring: the seconds scale. That ring spins counter-clockwise in 60 seconds, offering a clear and unparalleled way to display the seconds.

THE FLYING DOUBLE-AXIS TOURBILLON

The third arm is a flying tourbillon. It makes one rotation on its own axis in one minute. Being a part of the vertical platform, it has a second rotation axis, also in one minute. It is therefore a double-axis flying tourbillon.

Astronomia Regulator is a very elaborate work of horological engineering, whose complexity is made invisible. All that shows is what Jacob & Co. is famous for : exhilaration, unique design, watchmaking performance and exceptional craftsmanship.
