Abstract (en)

[origin: WO0004424A1] The invention concerns a timepiece comprising a mainspring with constant couple, having a balance spring and a balance wheel, the balance wheel (7) oscillation being maintained through an escapement mobile element (2) by moving a fixation point of the balance spring (6) when the oscillator passes through the oscillator impulse point, bringing about a circular motion of said balance spring (6) fixation point about the oscillator, thereby driving in rotation in time the mainspring-escapement assembly (2, 6, 7).
