To provide a switch device that prevents the intrusion of foreign objects, ensures shock resistance, and can improve operability, and a watch including the same.SOLUTION: A Switch device comprises: a cylindrical member 20 provided in an open hole 18 of a main unit case 2; an operation member 21 including an axis part 24 inserted into the cylindrical member 20 and a head part 25 provided on an outer end part of the axis part 24 and moving closer in a manner contactable to and separable from an outer surface of the main unit case 2; and a packing member 34 annularly disposed, along an outer periphery of the cylindrical member 20, between the outer surface of the main unit case 2 and the head part 25 and coming into elastic contact with the head part 25. Thus, the head part 25 is enabled to be in elastic contact with the packing member 34 when the head part 25 is pushed to be made contacted with the outer surface of the main unit case 2, which prevents the intrusion of foreign objects between the main unit case 2 and the head part 25 and ensures shock resistance. Furthermore, the operation member 21 can be operated while the head part 25 is pulled out to be separated from the packing member 34, and therefore the operability of the operation member 21 is improved.SELECTED DRAWING: Figure 2 【課題】異物の侵入を防いで、耐衝撃性を確保し、かつ操作性の向上が図れるスイッチ装置およびそれを備えた時計を提供する。【解決手段】本体ケース２の貫通孔１８に設けられた筒状部材２０と、この筒状部材２０に挿入する軸部２４、およびこの軸部２４の外端部に設けられて本体ケース２の外面に接離可能に接近する頭部２５を有する操作部材２１と、本体ケース２の外面と頭部２５との間に筒状部材２０の外周に沿って環状に配置され、頭部２５が接離可能に弾接するパッキン部材３４と、を備えている。従って、頭部２５を押して本体ケース２の外面に接近させた際に、頭部２５をパッキン部材３４に弾接させることができるので、本体ケース２と頭部２５との間における異物の侵入を防いで、耐衝撃性を確保できる。また、頭部２５を引き出してパッキン部材３４から離した状態で、操作部材２１を操作できるので、操作部材２１の操作性の向上が図れる。【選択図】図２
