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 optimise time reading, each of their indications were split into three 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 counter clockwise 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. 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.
Astronomia Tourbillon blends constant motion and extreme precision, achieved by exclusive, hand-wound Caliber JCAM10.
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.
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.
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 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.
