PROBLEM TO BE SOLVED: To provide a switch device and a timepiece capable of securing a good pushing operability, while increasing a rotational torque.SOLUTION: A switch device 3 includes: a guide member 31; an operation member 32; a torque O ring 34. The guide member 31 is fixed to a through-hole 15 of a case 1, and one end part is protruded to the outside of the case 1. The operation member 32 includes; an operation shaft part 32a inserted into the guide member 31; and an operation head part 32b exposed to the outside of the guide member 31 with one end part inserted therein. The operation member 32 is arranged for the guide member 31 in a manner capable of performing the rotational operation and the pushing operation. The torque O ring 34 press-contacts to the inner peripheral surface of the operation head part 32b and the outer peripheral surface of the guide member 31. The guide member 31 includes a first groove 31f formed along the peripheral direction in the outer peripheral surface and holding the torque O ring 34; and a second groove 31g formed so as to cross the first groove 31f in the outer peripheral surface and deeper than the first groove 31f.SELECTED DRAWING: Figure 2 |
