[Deeper, quieter, bluer. "UNITE with BLUE"] This Eco-Drive radio-controlled watch from the Citizen Collection captures the expression of water gently swaying in the deep ocean. "UNITE with BLUE" is a popular cross-brand project launched in 2023. Deeper, quieter, bluer. The structural color dial, which shows various expressions with the reflection of light, expresses a new blue based on the concept, "When it's blue, it's one world." This is a limited edition model. [CITIZEN COLLECTION] The Citizen Collection combines a design that's perfect for business settings with the functionality you'd expect from a wristwatch. This limited edition model is an adaptation of the popular Eco-Drive radio-controlled chronograph, evoking the expression of water gently rippling in the deep ocean. A white faceplate ring is added between the black bezel and deep blue dial to create a three-dimensional effect.
