What are the differences between the energy system of the Jacob & Co. Astronomia Four-Axis Tourbillon and its counterpart, the Three-Axis Tourbillon (Astronomia Revolution)?







Below, we'll explain the differences in the power techniques of the Three-Axis Tourbillon (Astronomia Revolution, or simply " Three-Axis" ) and the Four-Axis Tourbillon (or simply " Four-Axis" ), focusing on five crucial aspects: movement, mainspring, continuous force, rotating platform, as well as winding method.



1 . Movement Model and also Basic Structure



Three-Axis (Revolution): Movement JCAM48B, 434 parts, Jacob & Co.



Framework: Three-axis tourbillon (double-axis tourbillon + platform revolution since the third axis).



Four-Axis (Four-Axis): Movement JCAM54, 485 parts.



Structure: True four-axis (three-axis tourbillon + independent fourth-axis rotating support).



Platform reduced from 3 arms to two arms, shedding pounds and energy consumption, sustaining a 36-hour power reserve. second . Mainspring and Power Reserve



Similarities: Manual winding, single mainspring barrel, 36-hour power reserve, 21, 600 vph.



Differences primarily lie in load along with torque management:

2. Three-axis: Drives three axes + three-arm platform, reasonable energy consumption.

1. Four-axis: Drives four axes + two-arm high-speed system (60 seconds/revolution), higher speed, higher instantaneous load, stronger mainspring output torque, requiring much more precise constant force manage.



3. Continuous Force Device (Core Difference)

* Both utilize 1/6-second high-frequency constant pressure (synchronized with the balance steering wheel frequency), but the design and cargo differ:

* Three-axis (JCAM48B)

* Trademarked “whip torque adjustment”: Produces energy every 1/6 2nd, buffering mainspring ripple.

* Function: Protects the actual dual-axis tourbillon escapement, gets used to to three-axis speeds (60 seconds, 15 seconds, 60 seconds).

Quad-axis (JCAM54)



Next-generation high-frequency constant force: Integrated inside the tourbillon frame, allowing for better load capacity and quicker response.



Ideal for quad-axis top speeds: one minute, 18 seconds, 15 secs, and 60 seconds, with the 15-second axis being Astronomia's present highest speed, doubling the needs for constant force balance (Jacob & Co. ).



Officially referred to as the " fastest regular force mechanism in history, " it precisely charges in addition to discharges every 1/6 next, offsetting the significant torque variances caused by the high speed associated with quad-axis operation.



4. Rotation Platform as well as Power Distribution



Tri-axis: Three-arm platform, 60 seconds/revolution; tourbillon at 1 end, the other end that contains a timer, jewel, world, and other counterweights.



Quad-axis: Two-arm platform, 60 seconds/revolution; retains only the particular tourbillon and timer, removing the jewel/globe, reducing weight through approximately 30%, lowering strength consumption, and preventing unexpected power drops at higher quad-axis speeds.



5. Winding and Time Setting Mechanism



Three-axis: Traditional crown turning + time setting (side of the case).



Four-axis: No crown; changed by two 18K rose gold colored bow-shaped winding mechanisms within the case back, 180° revolving operation, suitable for a fully skeletonized design without a side overhead, while also optimizing the ability transmission path.



Differences Overview (Table)



Table | Item | Three-Axis (Astronomia Revolution) | Four-Axis (Four-Axis Tourbillon)



Movement | JCAM48B (434 pieces) | JCAM54 (485 pieces)



Tourbillon | Three-Axis (Dual-Axis + Platform Revolution) | Four-Axis (Three-Axis & Independent Fourth Axis)



Platform | 3 arms, 60 seconds/revolution | Two arms (weight reduction), 60 seconds/revolution



Constant Force | Whip-shaped torque adjustment | Brand new generation high-frequency constant push (faster, stronger)



Speed | 60s, 15s, 60s | 60s, 18s, 15s, 60s (higher speed)



Winding | Side crown | Double bow-shaped winding mechanism upon case back



Core Objectives | Excessive three-axis | Four-Axis and up. Ultimate high-speed stability



In short: The four-axis is a " power-enhanced and architecture-upgraded version" of the three-axis - using the new JCAM54 The movement, weight-reducing systems on both arms, stronger high-frequency constant force, and crownless winding support the fourth axis and higher speeds, while keeping a constant 36-hour power reserve.
