Abstract
An oscillating weight for an automatic watch is arranged to carry a bearing defining an axis of rotation (A—A) and is intended to be mounted on the frame of the watch. The mass member of the weight has a center of gravity (G) shifted with respect to the axis of rotation. In this weight, this mass member includes two parts that can be moved one (10, 18) in relation to the other (24), and arranged such that their relative movement causes a radial movement of the center of gravity (G) of the mass member. The mass member also has a securing device (13, 14, 16b) cooperating with the first and second parts, capable of occupying a first state in which the parts can be moved with reference to each other, and a second state in which the parts are rigidly secured to each other.

An oscillating weight for an automatic watch, arranged to carry a bearing defining an axis of rotation and intended to be mounted on a frame of the watch, including a mass member having a center of gravity shifted with respect to the axis of rotation, said member comprising:
- two parts that can be moved one in relation to the other, and arranged such that their relative movement causes a radial movement of the center of gravity of the mass member, and
- a securing device cooperating with the first and second parts, capable of occupying a first state in which said parts can be moved with reference to each other, and a second state in which said parts are rigidly secured to each other.
An oscillating weight for an automatic watch, the weight comprising a mass element with a bearing portion defining an axis of rotation and a remaining mass portion defining an outer radial extent, the mass element having a center of gravity shifted radially outwardly with respect to the axis of rotation, the mass element comprising:
- a first part;
- a second part movable relative to the first part and arranged such that the relative movement causes a radial movement of the center of gravity of the mass element, and
- a securing device cooperating with the first part and second part, said securing device occupying a first state in which said second part can be moved with reference to said first part and a second state in which said second part is rigidly secured to said first part.
