In recent years, the quartz watch has been gaining popularity and increasing its market share, because of the remarkable improvement in the styling and performance, that is, the realization of thinner stylig, higher precision, higher reliability and longer life. Especially, the improvement in the styling is worthy of attention;many watch movements of less than 2mm in thickness are realized and thin watches using the thin movements are favorably received by the publ ic. To the improvement in styling, the contribution has been made by the reduction in thickness of watch components such as quartz oscillator, IC, LC panel, battery, etc. Among these components, the reduction in thickness of the battery which occupies the largest space in the watch is most important. As such, we have developed highly reliable ultra-thin AgO batteries which are approximately lmm in thickness. In this paper, we will describe various measures taken in the design stage and some improvements made in the production stage to realize the ultra-thjn batteries.
