PROBLEM TO BE SOLVED: To provide an display plate for a watch, which is easily formed and regulates the rotation of a base without affecting a substrate. SOLUTION: An attachment part 10a of the base 10 consists of a column with a rectangular cross section, the corner part of which consists of curved surfaces. A pore 16a provided in the substrate 16 is formed so that it regulates the rotation of the base according to the attachment part 10a. Thereby, when the attachment part 10a of the base 10 is fitted into the pore 16a of the substrate 16, the rotation is regulated since the external surface of the attachment part 10a and the inner surface of the pore 16a abut on each other in the rotation direction. Since the corner part is formed as a curved surface, the forces at the time of engagement are prevented from concentrating onto the corner part of the pore 16a of the substrate 16 and causing damage.
