Abstract

A construction of an electronic wrist-watch has a greatly reduced overall thickness constituted by the super-position of the case back 1, at least two time indicating discs 4, 5 and the crystal 8. The remaining elements such as the motor 9, oscillator 14, battery 13 and gear train 10 are placed outside the periphery of the discs. The discs carry respective minute and hour hand marks 6, 7 (the minutes disc 5 being transparent) and are pivoted on a stud 3 on the case back 1. To reduce as far as possible the watch thickness while at the same time maintaining rigidity of the discs, they are supported at their peripheries, which are toothed and driven by the gearing, by rollers 18, 33. <IMAGE>
