Abstract (en)
[origin: CN113009803A] A moire-effect winding assembly 1, 10 for an automatic timepiece movement includes an oscillating winding mass 3, 13 which is movable relative to the movement 2. The winding mass 3, 13 is to be mounted to rotate on an axis 25 of the movement 2. Part of the winding mass 3, 13 forms a heavy part allowing the mass to oscillate in response to the movement of the timepiece and to the force of gravity. The assembly also includes an element 4, 14 that is stationary relative to the movement 2. The stationary element 4, 14 is arranged under the winding mass 3, 13. The winding mass 3, 13 at least partly displaces above the stationary element 4, 14. The stationary element 4, 14 includes a first relief pattern and the winding mass 3, 13 includes a plurality of through openings 28 defining a second pattern, so as to create a dynamic moire effect when the winding mass 3, 13 displaces above the stationary element 4, 14.
