| 发明名称 | Oscillating weight | ||
| 摘要 | The oscillating weight for a self-winding watch mechanism is made by molding a plastic material charged with heavy metal particles. Moreover, the plastic material is also charged with fibers, wherein said fibers form between 1.5% and 7% of the total weight of the charged plastic material, and the density of the charged plastic material is greater than 8. | ||

| 主权项 | 1. An oscillating weight for a self-winding watch mechanism formed by moulding a plastic material charged with heavy metal particles and with fibres, said fibres forming between 1.5% and 7% of the total weight of the thus charged plastic material, and the density of the charged plastic material being at least 8 times the density of water, wherein said fibres are selected from the group consisting of glass fibres and carbon fibres; and said heavy metal is tungsten. | ||
