Crystallised Essence of Time

The most precise light-powered watch in the world* with annual accuracy of +/- 1 second. The crystallisation of CITIZEN’s technology, craftsmanship and philosophy of watchmaking, all refined into the Caliber 0100.

*As of February 2019, for an autonomous analogue quartz watch, according to research by Citizen Watch Co., Ltd


Technology of Caliber 0100

The second hand of a watch counts out 31,536,000 seconds every year. A watch with accuracy of +/- 1 second per year must mark those millions of seconds with annual deviation within just one second. To mark the seconds with such perfect purity, all the watch’s individual components need to be made with greater precision.



This limited edition has a mother-of-pearl dial evoking the limitless scope of time in the natural world. The contrast between the mother of pearl pattern formed over many years and the second hand marking each precise second is a visual metaphor for the way time passes into eternity, moment by moment. It also makes this watch uniquely beautiful.
