<p>PROBLEM TO BE SOLVED: To provide a switch device and a watch, capable of easily performing unlocking operation and preventing useless rotation of an operation member in a lock state.SOLUTION: The switch device includes: a cylindrical member 13 attached to a through hole 16 of a watch case 1; an operation member 14 having an operation shaft part 24 inserted into the cylindrical member 13 and an operation head part 25; and a lock member 15 fixed in the operation head part 25. An engagement projection part 22 is formed on the cylindrical member 13, and the lock member 15 includes an elastic support part 33 to be elastically deformed in a radial direction with a space S from an inner peripheral surface of the operation head part 25 and a lock part 34 with which the engagement projection part 22 is elastically engaged. Thereby when the operation member 14 is depressed and rotated, the engagement projection part 22 elastically deforms the elastic support part 33 and the engagement projection part 22 can be engaged with the lock part 34. Further, only by rotating the operation member 14 against regulation force of the lock part 34, the lock part 34 can be disengaged from the engagement projection part 22.</p> |
