This oscillating mass has, on the one hand, a mount (4) which is annular or is in the form of an annular sector and is able to be fixed to the frame (1) and, on the other hand, a central part (7) located mainly or exclusively in one half of the surface delimited by the mount (4). ## Claims ### Claim 1 Automatic winding timepiece movement having an oscillating mass (4, 6, 7) fixed to a frame (1) pivoted on the exterior of the timepiece movement, this frame (1) having toothing (1b) meshing with a kinematic link connecting it to the ratchet of a barrel of the timepiece movement; characterised in that the oscillating mass has, on the one hand, a mount (4) which is annular or is in the form of an annular sector and is able to be fixed to said frame (1) and, on the other hand, a central part (7) located mainly or exclusively in one half of the surface delimited by said mount (4). ### Claim 2 Oscillating mass able to be fixed to a frame (1) pivoted on the exterior of a timepiece movement and having toothing kinematically connected to the ratchet of a barrel of said timepiece movement, characterised in that the oscillating mass has, on the one hand, a mount (4) which is annular or is in the form of an annular sector and is able to be fixed to said frame (1) and, on the other hand, a central part (7) located mainly or exclusively in one half of the surface delimited by said mount (4). ### Claim 3 (depends on 2) Oscillating mass as claimed in claim 2, characterised in that the annular mount (4) also forms an unbalance and comprises a heavier part and a lighter part, the central part (7) being fixed at one or several points to the heavier part of the annular mount (4). ### Claim 4 (depends on 3) Oscillating mass as claimed in claim 3, characterised in that the annular mount has openings (6) distributed over its lighter part. ### Claim 5 (depends on 2) Oscillating mass as claimed in claim 2, characterised in that the central part (7) is made in one piece with the mount (4). ### Claim 6 (depends on 2) Oscillating mass as claimed in claim 2, characterised in that the central part (7) represents a figure. ### Claim 7 (depends on 2) Automatic winding timepiece, in particular a wristwatch, comprising a timepiece movement and hands (10, 11), characterised in that the movement has an automatic winding mechanism, the oscillating mass of which is formed in accordance with claim 2, and in that the central part (7) of the oscillating mass moves on the same side of the movement as the hands (10, 11) but does not thereby interfere therewith. ### Claim 8 (depends on 7) Timepiece as claimed in claim 7, characterised in that the oscillating mass (4, 7) is pivoted on the exterior of the movement via a ball bearing (1, 2). ### Claim 9 (depends on 8) Timepiece as claimed in claim 8, characterised in that the oscillating mass (4, 7) is fixed to the inner frame (1) of the ball bearing whilst the outer frame (2) of this ball bearing is fixed to the periphery of a plate (3) of the movement. ### Claim 10 (depends on 8) Timepiece as claimed in claim 8, characterised in that the inner frame (1a) of the ball bearing has inner toothing driving, via a kinematic link, the ratchet of a barrel of the movement. ### Claim 11 (depends on 7) Timepiece as claimed in claim 7, characterised in that the plane in which the central part (7) of the oscillating mass (4, 7) moves is in parallel with the dial (9) of the timepiece or with the plate (3) of the movement if the timepiece does not comprise a dial, the hands (10, 11) being located between this movement plane of the central part (7) of the oscillating mass and the dial (9) or the plate. ### Claim 12 (depends on 7) Timepiece as claimed in claim 7, characterised in that the plane in which the central part (7) of the oscillating mass (4, 7) moves is in parallel with the dial (9) of the timepiece or with the plate (3) of the movement if the timepiece does not comprise a dial, this movement plane of the central part (7) of the oscillating mass being located between the dial (9) or the plate and the hands (10, 11); and in that the spindle(s) of these hands is(are) located out of the sweeping area of the central part (7) of the oscillating mass. ### Claim 13 (depends on 3) Oscillating mass as claimed in claim 3, characterised in that the central part (7) is made in one piece with the mount (4). ### Claim 14 (depends on 3) Oscillating mass as claimed in claim 3, characterised in that the central part (7) represents a figure. ### Claim 15 (depends on 3) Automatic winding timepiece, in particular a wristwatch, comprising a timepiece movement and hands (10, 11), characterised in that the movement has an automatic winding mechanism, the oscillating mass of which is formed in accordance with claim 3, and in that the central part (7) of the oscillating mass moves on the same side of the movement as the hands (10, 11) but does not thereby interfere therewith. ### Claim 16 (depends on 9) Timepiece as claimed in claim 9, characterised in that the inner frame (1a) of the ball bearing has inner toothing driving, via a kinematic link, the ratchet of a barrel of the movement.
