The oscillating weight includes a drive ring and a heavy sector. The drive ring includes an annular transmission portion which has a coaxial toothing and a second annular portion concentric to the annular transmission portion, the heavy sector being fixed to the second annular portion. The drive ring further includes a plurality of connecting elements which are elastically deformable and which connect the annular transmission portion to the second annular portion.

A transmission horological mechanism is disclosed, which includes: a transmission wheel including a driving plate, intended to pivot about a first axis of rotation in response to the movements of a driving wheel; and a link organ having a flexible portion and bearing a unidirectional transmission organ arranged to cooperate with an output wheel intended to drive a driven wheel when the driving wheel is displaced in a first direction of displacement. The link organ includes: a base secured to the driving plate and arranged to exhibit a rotational movement about the first fixed axis of rotation, in response to the movements of the driving wheel; and a first arm extending from the base and bearing the unidirectional transmission organ at its distal end, the flexible portion being arranged on the first arm.

An oscillating mass (1) for a self-winding timepiece including a carrier bow (2) including a first transmission part (20) provided with coaxial toothing (21) to drive the winding of the timepiece and a second supporting part (22), and including a heavy sector (3) or attached to the second supporting part of the carrier bow (2). The heavy sector (3) is attached to the carrier bow at several points via blom studs (4) with an uneven surface to form a reservoir for holding glue.
