Switching conversion means for converting the display position from the switching conversion means to the display position of the pointer in the displayed display range, target position storage means for storing the display position from the switching conversion means as the movement target position of the pointer, and storing the current display position of the pointer. If the direction is determined by comparing the display position storage means with the target position and the display position stored in the target position storage means and the display position storage means, and there is no match. A comparison / coincidence detection means for outputting a direction signal and a step signal to the display position storage means until they coincide with each other, and a driving signal relating to the hands in response to the direction signal and the step signal from the comparison / coincidence detection means. And a motor for driving the hands in response to the drive signal. Mode switching data is also converted to a display position by the switching converter and output. As a result, one of the hands may display the mode, and the other hand may display the data of the selected additional function.

The switching conversion means in the multifunction display timepiece of the present invention normally outputs the display positions of the hour hand and the minute hand based on the current time data in the time display mode. When the display mode changeover switch is operated, the changeover means converts the display position into a display position in a set display range based on data from the additional function means according to the operation, and outputs the display position. I do. The display data is displayed by comparing the data of the target position storage means for storing the display position with the data from the display position storage means for storing the current display position, discriminating the direction, and driving the hands until they match. It can be displayed in response to the mode switch. Further, by converting the display mode data into the display position and outputting the data by the switching conversion means, the data of the additional function selected by each of the hour hand and the minute hand and the mode of the display data can be displayed. Further, since the switching conversion means converts the input data to the display position, an arbitrary display range can be set, and a display device in which a large number of additional function data are divided into a predetermined display range can be provided. Further, the comparison / coincidence detecting means determines the direction when the display position data changes, and outputs a signal for driving the hands until the display position data coincides with the display position, so that the comparison / coincidence detection means can reciprocate within the divided display range. When the mode changes, the display moves to the set display category.
