Abstract (en)
[origin: WO2010081500A1] This is a horological movement of the type with automatic winding and comprising a frame (4, 24, 42) carrying a drive member, connected kinematically to a mechanical oscillator (9, 10) to maintain its oscillations, notably by means of an escape wheel (8), and an automatic winding mechanism comprising an oscillating mass (1) designed to supply the drive member with energy. In accordance with the features of the invention, the mechanical oscillator and the escape wheel are pivoted on the oscillating mass. The movement preferably also comprises differential gearing (14) which has a first input (17) connected kinematically to the drive member, a second input (18) connected kinematically to the oscillating mass (1), and an output (19) connected kinematically to the escape wheel (8) in order both to transmit energy to the latter from the drive member and to compensate for the movements of the oscillating mass relative to the frame (4, 24, 42).
