Citizen Watch: Photon Eco-Drive Blue BJ6560-53W

Citizen Photon Eco-Drive Blue: light at the heart of the dial

The Citizen Photon Eco-Drive Blue, reference BJ6560-53W, celebrates 50 years of Eco-Drive technology in a limited edition of 5,000 pieces worldwide. Its black dial reveals blue reflections through several openwork metal layers. A structural color film, placed beneath these cutouts, allows the shades to vary according to the light and the angle of view. A yellow second hand highlights this composition, which is inspired by the properties of light.

The Photon features an octagonal case with rounded corners, measuring 39.6 mm in diameter and 9.85 mm in thickness. Both the case and the bracelet are crafted from Super Titanium and finished with Duratect titanium carbide, which increases surface scratch resistance while maintaining a silver hue. The complete watch weighs 82 g. A double-domed sapphire crystal with an anti-reflective coating protects the dial, which features luminescent hands and indices.

The Citizen E036 caliber is a quartz movement powered by light, whether natural or artificial. After a full charge, it has a power reserve of approximately 365 days. Its accuracy is rated at ±15 seconds per month. The three-hand display prioritizes hours, minutes, and seconds, with no date window. An insufficient charge warning reminds the user to expose the watch to light.

The silver Super Titanium bracelet extends the lines of the case. It fastens with a push-button safety deployment clasp. Water-resistant to 5 bar, or 50 m, this Photon features a case back engraved with the Eco-Drive anniversary logo and an individual serial number. It is delivered in a special presentation box featuring the openwork motif of the dial and includes a 3-year international Citizen warranty from PAUSE.

Why choose this watch?

The Photon Blue features a dial whose relief and nuances evolve with the light. The contrast between the silver tone of the titanium, the blue reflections, and the yellow second hand gives it a distinct identity without cluttering the display. Its 39.6 mm dimensions and 82 g weight allow one to enjoy this construction in a compact format.

The technical appeal lies in the combination of hardened Super Titanium, anti-reflective sapphire, and an Eco-Drive movement offering about one year of power reserve after a full charge. The individual numbering and the anniversary box complete an edition that illustrates fifty years of development in light-powered watchmaking.

About the Citizen brand

Citizen is a Japanese watchmaking house founded in 1918. It develops its own technologies and movements, with a particular focus on light-powered energy. In 1976, it launched its first analog watch using this energy, which was the origin of the technology known today as Eco-Drive.

The Photon celebrates this heritage by making the passage of light a visible element of its design. Its multi-layer dial and E036 caliber extend this innovative approach. Discover other models in our Citizen watch collection.
