During this time, I came across washi paper, which has been used since ancient times to bring in light, such as shoji screens, paper lanterns, and paper lanterns.

Among them, Tosa washi, one of the three major types of washi, is used for the dial.

The unprecedented ``Eco-Drive'' was born here, where you can enjoy the texture and expression of washi paper that changes when exposed to ``light.''

Rather than printing directly on washi paper, we use a double structure with a transparent top plate.

This structure not only makes it possible to print clearly, attach metal typesetting, and express the Rising Light pattern that covers the entire surface, but also improves strength. This is where an innovative structure was born that brings out the charm of Tosa Washi to the fullest.

No need for regular battery replacement

Photovoltaic power generation ``Eco-Drive'' is Citizen's original technology that converts sunlight and small amounts of indoor light into electricity to keep the clock running.

Once fully charged, it will continue to operate for a long time even in the absence of light, so there is no need to regularly replace the batteries.

Scratch-resistant, lightweight, and rust-resistant

``Super Titanium'' is a material made using unique titanium processing technology and surface hardening technology (Duratect).

It is 40% lighter than stainless steel and has a surface hardness 5 times more.

Reduces reflection and makes the dial easier to read

Clarity Coating is a glass coating technology that allows approximately 99% of light to pass through, reducing reflections and making the dial easier to read.

Even in sunny places such as parks and beaches, you can read the time clearly as if there was no glass.
