A push button capable of improving shock resistance and a timepiece equipped therewith are provided. This push button includes an operation member having a shaft section inserted into a through hole of a case and a head section provided on the outer end of the shaft section, and an elastic member which presses the head section toward the outside of the case or is elastically deformed, and this elastic member includes a buffer section that buffers a pressure externally applied to the head section which is greater than a predetermined pressure. Accordingly, when a pressure greater than the predetermined pressure is applied to the head section, the head section comes in contact with the buffer section while elastically deforming the elastic member so as to buffer the pressure. By this structure, shock resistance is improved.

The arbor further includes an entry ramp arranged to push back radially the first resilient arm and the second resilient arm, to allow the plate to be placed on the arbor.

An elastic retaining member is for attaching a horological component to a support element. The retaining includes an opening into which the support element is capable of being inserted. The retaining member also includes rigid arms and elastic arms defined between the connection zones of the retaining member. The arms contribute to procuring elastic gripping of the support element in the opening, each rigid arm being provided with a single convex contact zone of the retaining member capable of engaging with a corresponding convex contact portion of the support element.
