A movement of a multifunction timepiece includes a first train wheel rotation center, and a second train wheel rotation center. A train wheel for indicating calendar information is arranged to be rotatable relative to one of the first train wheel rotation center, and the second train wheel rotation center. When the first train wheel rotation center is arranged with a train wheel for indicating calendar information, the calendar information can be indicated by a small hand rotated to move by the train wheel, when the second train wheel rotation center is arranged with a fan shape hand operating train wheel for indicating the calendar information, the calendar information can be indicated by a small hand moved in a fan shape operating train wheel.
