▎ 摘　　要

NOVELTY - A component is made of a composite material comprising an organic matrix reinforced with graphene. The organic matrix is made of a polymer having Young's modulus of 2 GPa or more, preferably 3 GPa. USE - Component e.g. case, circle of casing, middle and bottom portions, bezel, pusher, bracelet link, bracelet, dial, bridge and plate of watch (all claimed). ADVANTAGE - The component has improved yield stress and excellent rigidity and mechanical properties. The composite material has high chemical and thermal performance and resistance to harsh environment.
