Eco-Drive RING

Pursuit of New Value

To highlight the value of CITIZEN’s core technology, the light-powered Eco-Drive, a total of eight concept models were unveiled between 2009 and 2012. The models were selected through an in-house competition. The only rule was that they had to be 'powered by light.' With no other restrictions, designers were free to propose new products from a completely blank slate. The models were announced on a grand scale at BASELWORLD, the world’s largest watch fair held in Switzerland, drawing significant attention. Furthermore, the initiative did not end with the unveiling of the concept models; efforts were made to mass-produce them with their original designs as much as possible. Four of the announced models were produced in limited quantities, and their technology and design codes had a major influence on subsequent models.

Radiant Icon of a Near‑Future

This watch was created as a symbol of the "fusion of technology and beauty," inspired by modern architecture. Its striking design and unprecedented light-harvesting system come together to create a piece of art that expresses the concept of the near future through a watch. The structural combination of sapphire glass on the case side and the metal pillars of the central case is truly reminiscent of modern architecture. It balances the functionality of protecting the movement with the visible beauty of sparkling glass. Rather than a simple three-hand watch, it also features a new expression of the moon phase, symbolizing the relationship between light and shadow that this watch represents. The index design, with its playful focus on the side view, contributes to a flawless overall design. Placing what was once in front to the side—while it sounds simple, positioning the solar cell on the side was a challenge no one had ever attempted before. Thanks to the engineers' efforts, innovative technology and a novel form have come together. This product was introduced to the world with the catchphrase "The Monster That Absorbs Light." This design, which has pioneered the future, absorbs light and radiates it brilliantly, becoming a crystallization of hard work. The attention to each part and the overall balance are beautifully embodied as a single symbol.
