Abstract:
1. A multifunction timepiece comprising: a main plate constituting a base plate of a movement; a hand setting stem for correcting display; a switching mechanism for switching a position of the hand setting stem; a dial for displaying time information; a small hand for displaying the time information or calendar information; wherein the movement is provided with a first train wheel rotational center for a train wheel used in fabricating a multifunction timepiece of a first type having an arrangement of a small hand of a first type, a second train wheel rotational center for a train wheel used in fabricating a multifunction timepiece of a second type having an arrangement of a small hand of a second type, a third train wheel rotational center for a train wheel used in fabricating a multifunction timepiece of a third type having an arrangement of a small hand of a third type, and a fourth train wheel rotational center for a train wheel used in fabricating a multifunction timepiece of a fourth type having an arrangement of a small hand of a fourth type; wherein the first train wheel rotational center is provided with a train wheel guide portion for guiding a train wheel member moving to rotate centering on a position thereof to be able to move to rotate; wherein the second train wheel rotational center is provided with a train wheel guide portion for guiding a train wheel member moving to rotate centering on a position thereof to be able to move to rotate; wherein the third train wheel rotational center is provided with a train wheel guide portion for guiding a train wheel member moving in a fan shape centering on a position thereof to be able to move in the fan shape; wherein the fourth train wheel rotational center is provided with a train wheel guide portion for guiding a train wheel member moving in a fan shape centering on a position thereof to be able to move in the fan shape; wherein the train wheel rotational center of the train wheel member moving to rotate is arranged at a position between a main plate center of the main plate and a main plate outer shape portion of the main plate; wherein the train wheel rotational center of the train wheel member moving in the fan shape is arranged at a position between the main plate center of the main plate and the main plate outer shape portion of the main plate; a train wheel for displaying calendar information is rotatably arranged at the third train wheel rotational center or the fourth train wheel rotational center; when a train wheel for displaying time information is arranged at the first train wheel rotational center, the time information is constituted to be able to be displayed by the small hand moving to rotate by the train wheel, and when a train wheel for displaying the time information is arranged at the second train wheel rotational center, the time information is constituted to be able to be displayed by the small hand moving to rotate by the train wheel; and when the fan shape moving hand train wheel for displaying the calendar information is arranged at the third train wheel rotational center, the calendar information is constituted to be able to be displayed by the small hand moving in the fan shape by the fan shape moving hand train wheel, and when the fan shape moving hand train wheel for displaying the calendar information is arranged at the fourth train wheel rotational center, the calendar information is constituted to be able to be displayed by the small hand moving in the fan shape by the fan shape moving hand train wheel.
