CITIZEN PROMASTER UNITE with BLUE limited edition model
inspired by the beautiful oceans that unite our world

CITIZEN Watch is launching a limited-edition CITIZEN PROMASTER UNITE with BLUE model (7,000 pieces worldwide) in June 2023 featuring a structural colour dial*1, inspired by the beautiful oceans that unite our world.

* Final price, launch date, and number of pieces may be subject to change.


The limited-edition UNITE with BLUE model is a light-powered Eco-Drive*2 watch with a captivating dial featuring countless shades of blue inspired by the beautiful oceans that unite our world.

The dial uses 100% recycled polycarbonate materials. The structural colour ink on the surface of the dial, created by FUJIFILM Corporation, produces an incredible variety of glittering colours inspired by the beauty of the ocean. The pigment-free ink uses light reflecting off the surface of the microstructures in the ink to create a range of hues and tones. The watch is powered by light, a form of clean energy, and the unique dial utilises light to create beautiful colours, perfectly complementing the Eco-Drive technology inside.

The two-tone bezel is reminiscent of a sparkling emerald green ocean, coordinating beautifully with the colours on the dial. The strap is made from biomass-based polyurethane which includes plant-based materials.
