A watch member according to the present invention comprises: a layer (I) formed from a composition (I) that contains a polyrotaxane (A) containing a macrocycle having an activated hydrogen group, and an isocyanate compound (B); and a layer (II) containing a carbodiimide compound and a polyurethane, a polycarbonate, or a polyester. Alternatively, a watch member according to the present invention is obtained by laminating together a precursor layer (I') comprising a composition (I) that contains a polyrotaxane (A) containing a macrocycle having an activated hydrogen group, and an isocyanate compound (B); and a layer (II) containing a carbodiimide compound and a polyurethane, a polycarbonate, or a polyester, and then heating the laminated precursor layer (I') and the layer (II). |
