PURPOSE:To make it possible to change appearance designs selectively by changing time display members and cases and also by using common movement. CONSTITUTION:Switch bodies 1 and 2 are provided with contacts 1a and 1b, and 2a and 2b integrally at positions shifted in movement by a phase of 90 deg. and external operating members contained in cases of different kinds are operated to let respective contacts interlock by selective engaging. Further, switch bodies 1 and 2, battery 3 and crystal vibrator 4 are plane-arranged without overlapping on the same section. For example, using a laterally-longer case, cell 11A and common movement allows contacts 1a and 2a to function corresponding to operating members 6 and 7, and using a longitudinally- longer case, cell 11B and the common movement make contacts 1b and 2b function corresponding to operating members 6' and 7'. |
