What is the power source of the Astronomia Four-Axis Tourbillon?



The power resource and core configuration from the Astronomia Four-Axis Tourbillon tend to be as follows:



1 . Basic Power: Manual-winding mainspring
Movement: JCAM54 in-house manual-winding movement
Energy Core: A single, extra-large diameter mainspring barrel located at the end of the movement, providing fundamental power to the entire vertical 3d rotating platform.

Power Reserve: 36 hours (maintained even below high-speed four-axis rotation)
Rate of recurrence: 21, 600 vph (3Hz)

2 . Power Distribution: High-frequency constant force device (patented)

Due to the extremely high speed in the four-axis tourbillon (up to fifteen seconds/revolution) and the heavy masse, the mainspring output torque fluctuates greatly and are not able to directly drive the escapement. Therefore , a patented high-frequency constant force device is actually incorporated:

Function: As a "power buffer, " it very first stores energy and then produces it to the escapement system with a constant torque, making sure accurate timekeeping under excessive rotation (1440°/hour accuracy). Area: Integrated within the tourbillon crate, adjacent to the escapement.

three. Winding Method
No conventional crown: Manual winding as well as time setting via **two reversible 18K rose gold "bow-shaped winders" on the case back**.
