A gear train mechanism stop device is used in a timepiece having clock signal producing IC, a stepping motor for generating a given rotational movement in response to a clock signal produced from the IC, at least hour and minute hands, and a gear train mechanism for transmitting the rotational movement from the motor to hands so as to make the hands move in a given movement, which is selectively engaged with a specified gear in the gear train mechanism so as to stop rotation of the specified gear. The device comprises an engaging member movable between an engaged position at which the member is engaged with the specified gear in the gear train mechanism in the axial direction of the specified gear so as to stop rotation of the specified gear, and a disengaged position at which the member is disengaged from the specified gear and allows the specified gear to rotate so as to allow rotational movement transmission from the motor to the hands, and an operation member for selectively moving the engaging member between the engaged and disengaged positions, wherein the specified gear is made of a synthetic resin.
