Abstract (en)
[origin: WO2020234665A1] The watch movement with automatic windup comprises an oscillating weight (7) and a barrel (3) which are arranged concentrically. The oscillating weight is arranged so as to wind up the barrel, which is positioned at the centre of the movement. The barrel drum (13) is mounted on the frame of the movement so as to be rotatable in a single direction of rotation, the single direction causing the barrel (3) to be wound up. The oscillating weight and the barrel drum are also arranged so as to be rigidly connected to one another when the oscillating weight (7) rotates in the single direction of rotation.
