A push-button structure for a timepiece having a case and a circuit board, comprising:

• a pressure conductive rubber which is rendered electrically conductive when applied with pressure;
• a holder attached to an upper surface of said circuit board and holding said pressure conductive rubber in a fixed place;
• a spring member attached to an upper surface of said holder and including a connection portion and a plurality of tongue portions interconnected by the connection portion, each of said tongue portions having a bridge-shaped central portion which is raised from said holder, and said spring member further including a substantially centrally located arcuated notch and a bifurcation extending therefrom;
• and
• a push-button slidably disposed in said case and having its end engaging said notch, the end of said push-button being located directly above said pressure conductive rubber to press said rubber when said push-button is depressed.
