The design is inspired by a canon, a kind of classical music with a rich, multi-layered timbre created by repeating one melody starting at different times.

The case—with bezel and case in three different colours and an intriguing spiral shape—presents a series of beautiful curves like overlapping melodies.

The 2.0 mm diamond at one end of the spiral emits a timeless gleam, while the small empty space between the case and the diamond gives a light, airy quality to the whole design.

Technology to turn light into energy Eco-Drive is a CITIZEN core technology that generates energy even from dim light and stores the surplus on a power cell. It is environment friendly and keeps running for over six months on a single full charge even in the dark, eliminating the need to replace batteries.
Just as plants convert light into energy through the process of photosynthesis, so Eco-Drive drives the hands of our watches. That is one of the key concepts behind the Ambiluna collection.
