The remontoir d'égalité gravity escapement mechanism

While developing a clock and researching methods to achieve a stable, constant‑force drive—similar to the solutions used in high‑precision mechanical timepieces—I designed this model and decided to share it. The mechanism follows the principles of a traditional remontoire, a device widely used in high‑grade clocks from the 17th century onward. A remontoire is essentially an intermediate power‑buffering system. Instead of allowing the escapement to be driven directly by the main spring or weight—both of which deliver uneven torque as they unwind—the remontoire periodically rewinds a small secondary spring or lifts a small weight. This secondary element then provides a short, consistent burst of force to the escapement.
