PURPOSE:To obviate the occurrence of watch deviations even if changing over of the watch and timer is performed by so arranging the changeover positions of a changeover switch that the watch and timer are adjoining and the outer side of either of these becomes watch adjustment. CONSTITUTION:A counter C performs specified counting operations and forms output signals as its operations are controlled by a fast feed switch SW1, slow feed switch SW2, backward feed switch SW3 and changeover switch SW4. If it is assumed that the backward feed operation be performed, then the switches S1, S2 close and the reversible counter U/D makes reverse counting and therefore subtraction outputs are applied to a 1/10 counter C2, 1/6 counter C4, 1/24 counter C5 and the displays of display devices M and H are subsequently reversed. |
