Mechanical Model

This model features a CITIZEN-made mechanical movement. The first watch CITIZEN produced in 1924 was a mechanical pocket watch. This new model builds on our mechanical watch heritage and long-standing commitment to accuracy and aesthetics.

Eco-Drive with Annual Accuracy of ±1 Second

This model features the Caliber 0100, an Eco-Drive movement which is accurate to within a world-beating* 1 second per year. Without any reliance on time signals from radio towers or GPS satellites, it tells the accurate time with deviation of less than 1 second per year, based only on its own autonomous mechanism.

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

Eco-Drive with Annual Accuracy of ±5 Seconds

This model features an Eco-Drive movement which is accurate to within ±5 seconds per year. The summation of all CITIZEN’s technologies. It tells the accurate time and keeps on running powered only by light, without the need for regular battery replacement.
