An irreplaceable feeling of comfort in your arms

One of CITIZEN 's flagship models,

Introducing a ceramic bezel model from the Eco-Drive One series, the world's thinnest light-powered watch.


The movement is only 1 mm thick.

It contains over 80 parts and CITIZEN 's top technology.

It is poured into this case.



It's said that the Eco-Drive One surprises you three times.

1. The beauty of its form.
"Style is about subtraction." By stripping away unnecessary elements, the inherent beauty of the watch is expressed to the fullest extent.
Its understated yet dignified design and refined form are breathtakingly beautiful.


2. Lightness.
The moment you hold it in your hands, you can't help but gasp in surprise at how light it is.
The bezel is made of zirconia ceramic, which is thin and lightweight yet possesses high hardness.
It possesses both a sophisticated design and undeniable strength.


3. Comfort
The band, designed to be thin to match the case and with as many small links as possible,
It's so comfortable you might forget you're even wearing it.
Here you'll find a new level of wearing comfort that no wristwatch has ever offered before.


Hairline finish on the bezel and guilloché engraving on the dial, etc.

The delicate design details, even in the smallest parts, give it a sophisticated image.


The Eco-Drive One embodies everything CITIZEN has to offer as it celebrates the 50th anniversary of Eco-Drive.

We bring that pride and beauty to your wrist.
