Annual Accuracy of ±1 Second Eco-Drive

SCROLL

Each individual second:
The crystallised essence of time

This watch promises to do two things: To tell the time with a deviation of less than one second per year.
And to express each and every second with true purity and beauty.

We refined all the elements of the watch in this crystallisation of CITIZEN technology.
The most precise light-powered watch in the world*
with annual accuracy of ±1 second.
When every second is a miracle of purity.

As of May 2021, for an autonomous analogue light-powered quartz watch, according to research by Citizen Watch Co., Ltd.

Fine lines radiating from the centre of the silver dial in a sunburst pattern give the watch character, authority and style. The beautiful mirror finishes and the sense of weightiness express stainless steel’s unique appeal as a material and endow this timepiece with real presence.

18K white gold / Crocodile

CITIZEN’s passion for pioneering the future of the watch comes together with a design that fuses universality and innovation. The case, band and the crown have sharp edges to evoke a crystal motif.

Super Titanium™ (Duratect α)

The combination of a lustrous black dial, a titanium case and a metal band inspired by a crystal motif give this limited-edition model a simultaneous sense of solidity and precision. The watch absorbs light via an array of tiny apertures in the dial, enabling it to keep marking the individual seconds with extreme accuracy.

AQ6020-53X

AQ6020-53X

Super Titanium™ (Duratect α)

A mother-of-pearl dial evokes 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.

The eagle mark:
Symbol of The CITIZEN

The eagle symbolises The CITIZEN’s twin commitments to “looking ahead and pursuing the ideal” and to “becoming an integral part of users’ lives.” The mark is discreetly engraved on the dial and crown of some models.
