The aesthetics of subtraction
A beauty that strips things away to express the very essence of the watch. Thinness beyond imagination. A wrist feel that defies gravity and stress.
The joy of becoming one with your watch the moment you put it on.
Driven by a movement just 1.00 mm thick, it is the world’s thinnest light-powered watch.*Eco-Drive One is a work of art that only CITIZEN could create.Because we are a manufacture d’horlogerie, performing every stage of manufacturing, from the making of individual parts through to final assembly.
Wholly satisfying but light too.
Masculine and Feminine and all the roles
and labels that tie people down.
We want to be free. Free from them all.
There's only one thing we want.
Elegance. In its purest form.
TECHNOLOGY & TECHNIQUE
TECHNOLOGY & TECHNIQUE
Pioneered by CITIZEN in 1976, Eco-Drive is the technology at the heart of Eco-Drive One. Light passing through the dial is converted into electrical energy by a solar cell. This electrical energy then charges the power cell and is sent to the motor to drive the hands. Eco-Drive can now charge in dim light as well as sunlight, eliminating the need to replace batteries. Running time has also increased to over six months on a single full charge. Eco-Drive continues to evolve, redefining the limits of the possible.
The assembly process
When the 85 components are ready, they are passed on to CITIZEN’s skilled master craftsmen for hand-assembly. Our craftsmen had to invent entirely new assembly techniques to achieve the record-setting thinness of the watch. With a 1.00mm thick movement and a 2.98 mm case, Eco-Drive One is the world’s thinnest light-powered watch. We succeeded in making it because CITIZEN is a manufacture d’horlogerie, doing everything from making the individual parts to performing final assembly in-house.
The materials for the 2.98mm case
Using materials that combine thinness and strength. The thinner a watch gets, the more beautiful it becomes. The only problem is whether it will be strong enough. With Eco-Drive One, we use new materials that combine both thinness and strength.
