PROBLEM TO BE SOLVED: To provide a switch mechanism that enables switching operation using a rotary bezel while ensuring airtightness in a case, with a simple structure, and provide a timepiece.SOLUTION: A switch mechanism 10 includes: a rotary bezel 7 in which a projection part 71 is formed on the inside surface, and which is provided in a rotatable manner; a support member 81; and a vibration body 8 which has a piezoelectric element 82 pasted to the support member 81, and includes a contact terminal 83 electrically connected to a circuit board 5 on the base end side, and of which a free end side contacts with the inside surface of the rotary bezel 7, and at least the free end side can be elastically deformed. The switch mechanism makes the piezoelectric element 82 output according to the rotation of the rotary bezel 7, and performs switching operation on the basis of the output. |
