Abstract

PURPOSE:To make possible time correction with simple operations by providing two switching mechanisms which are controlled according to pulling and rotating of a winding crown. CONSTITUTION:A setting lever 18 is oscillated by pulling of a winding crown 11 to be contacted with or separated from contact pins 19, 20, and the protruding part (a) is contacted with or separated from switch contact springs 21, 22 by the rotation of the winding crown 11. Then, if the setting lever 18 is set neutral by pulling one step the winding crown 11, the AND circuits 38, 30 of a correction target select gate group 37 go ON and the date and day are selected as the correction target, whereby the display of the hour, minute and second is ereased from a display device 13 and winding crown direction indicating parts 15, 16 are lighted. When the winding crown 11 is rotated to the right or left, the protruding part 17a contacts the switch contact spring 21 or 22 and the AND circuit 43 or 44 goes ON, by which the date or day is corrected.
