Abstract
The oscillating weight includes a primary oscillating weight (10) secured to a drive arbor (6) and at least one secondary oscillating weight (20), which is mobile relative to the primary weight to cause the initial impulse. The secondary weight (20) is formed by a part assembled to the primary weight (10) from the exterior, while being able to have a travel between two stop members (12a, 12b) of a guide means (14, 18) located on the periphery of the primary weight (10).
