Citizen BJ6569-59X Eco-Drive Photon 50th Anniversary Limited Edition Watch

Citizen Eco-Drive PHOTON 50th Anniversary Limited Edition represents the evolutionary pinnacle of half a century of pioneering innovation in solar technology. Created to celebrate the fiftieth anniversary of the world's first light-powered analog watch, introduced by Citizen in 1976, this extraordinary timepiece pays tribute to the photon with a futuristic aesthetic and exceptionally fine craftsmanship.

At the heart of the watch is the innovative Eco-Drive E036 caliber, capable of converting any light source into stored energy, ensuring 365 days of continuous operation on a full charge, with no need to replace the battery.

The multi-layered dial is inspired by the iconic double-slit physical experiment: two overlapping metal elements with wavy openings reveal a structurally colored surface, creating iridescent reflections and dynamic color shifts as the light and viewing angle change.

The 39.6 mm case with a rounded octagonal geometry and the integrated bracelet are forged from Super Titanium™ with Duratect hardening treatment, ensuring extreme lightness, hypoallergenic comfort, and scratch resistance up to five times greater than steel. Protecting the dial is a prestigious double-curved sapphire crystal with exceptional clarity.

Produced in a strictly limited worldwide edition of 5,000 numbered pieces, each with a custom case back featuring the 50th Anniversary logo, the watch offers guaranteed water resistance and a profile of just 9.9 mm, ideal for formal and sporty everyday wear.
