"LIGHT in BLACK" was born in 2015 as a limited collection themed around "Light and Time," symbolizing CITIZEN's solar-powered technology "Eco-Drive." In 2026, to commemorate the 50th anniversary of Eco-Drive, the "LIGHT in BLACK Eco-Drive 50th Anniversary Edition" will be released, featuring a black and gold color scheme reminiscent of the original "LIGHT in BLACK." The dial design, inspired by the "50th anniversary," combines five different angled patterns that beautifully reflect light.
