A wristwatch comprising:

• a wrist watch case;
• a rotating operation member which has a through-hole formed therein in an axial direction;
• a guide pipe member which is attached to a side wall portion of the wristwatch case so as to pass through an interior of the wristwatch to an exterior, wherein at least a portion of the guide pipe member is arranged within the through-hole of the rotating operation member;
• a pressing operation member which is inserted into the guide pipe member, and which is movable within the guide pipe member and within the through-hole of the rotating operation member, wherein the pressing operation member is press-operable from one opening of the through-hole, and the pressing operation member is provided so as to rotate integrally with the rotating operation member, when the rotating operation member rotates;
• a first coil spring which is arranged within the through-hole of the rotating operation member and biases the pressing operation member outwardly in the axial direction;
• a second coil spring which is arranged within the through-hole of the rotating operation member and biases the rotating operation member outwardly in the axial direction;
• and
• a locking section which locks the rotating operation member in a locked state in which the rotating operation member is inoperable to perform a function associated therewith,
• wherein when the locking section locks the rotating operation member in the locked state, the pressing operation member is operable to perform a function associated therewith, and when the locking section unlocks the rotating operation member so that the rotating operation member is in an unlocked state, the pressing operation member is inoperable to perform the function associated therewith.
