In 1976, Citizen introduced the world's first analogue light-powered watch. The Eco-Drive PHOTON marks that technology's 50th anniversary, and it is limited to 5,000 pieces worldwide.
The dial is the reason this watch exists. Two metal plates with ripple-like slits are layered one over the other, revealing a structural colour film beneath — and that film sits directly over the solar cell. Light entering through the slits produces colours that shift as you move, in a visibly three-dimensional effect that changes in real time. The design references the double-slit experiment, the physics demonstration that revealed light behaves as both wave and particle. On a watch celebrating fifty years of turning light into power, the dial and the power source are literally the same component.
Inside is Caliber E036, which Citizen describes as the next-generation Eco-Drive standard. A complete redesign of the circuit system lets it run for roughly approximately 6 months on a full charge and drive heavier hands despite its thinness, holding ±15 seconds a month. The octagonal 39.6mm case is Super Titanium, just 9.9mm thick, on an integrated titanium bracelet. A yellow seconds hand provides the single point of contrast, and the caseback is engraved with the 50th Anniversary logo and an individual edition number.

Why You'll Love It
- The dial's colour genuinely changes as you move — two slitted metal plates over a structural colour film create shifting hues and real visual depth, not a printed gradient that only looks different in photographs.
- The structural colour film sits directly over the solar cell, so the dial's optical effect and the watch's power source are the same component. For a 50th anniversary Eco-Drive, that's a concept carried all the way through.
- Limited to 5,000 pieces worldwide, with the caseback engraved with both the Eco-Drive 50th Anniversary logo and your watch's individual edition number.
- Caliber E036 is Citizen's new next-generation Eco-Drive standard, making its debut here — a full year of running time from one charge, in a 9.9mm case.
- A complete redesign of the circuit system lets this movement drive heavier hands despite its thinness, which is what allows the substantial handset over such a complex dial.
- Super Titanium is lightweight, highly scratch-resistant and hypoallergenic — and at 9.9mm on an integrated bracelet, this wears exceptionally comfortably.
- The octagonal case and integrated titanium bracelet give it a distinctly modern architecture rather than a conventional round-case-and-lugs construction.

Technical Specifications
The Citizen Eco-Drive PHOTON BJ6560-53W is a 39.6mm limited edition of 5,000 pieces worldwide, marking the 50th anniversary of Eco-Drive. It's powered by Caliber E036 — Citizen's next-generation Eco-Drive standard — with approximately 6 months power reserve and ±15 seconds per month accuracy. The octagonal Super Titanium case measures just 9.9mm thick, with a Sapphire Glass, water resistant to 50 metres. The multi-layered dial uses two slitted metal plates over a structural colour film placed above the solar cell, producing colour that shifts with viewing angle, with a yellow seconds hand. The caseback is engraved with the 50th Anniversary logo and an individual edition number.

Frequently Asked Questions
What makes the dial change colour?
The dial is built in layers. Two metal plates with ripple-like slits sit one over the other, and beneath them is a structural colour film. Structural colour comes from the way light interferes with microscopic surface structures rather than from pigment — the same principle that makes a butterfly's wing or an oil film shift colour. As you move the watch, light passing through the slits produces different colours and a genuine sense of depth.
What is the double-slit experiment?
It's the classic physics demonstration in which light passed through two narrow slits produces an interference pattern, showing that light behaves as both a wave and a particle. Citizen took it as the design concept for a watch marking fifty years of converting light into power — which is also why the collection is called PHOTON, the name for a single quantum of light.
What makes this a limited edition?
Production is capped at 5,000 pieces worldwide. The caseback is engraved with the Eco-Drive 50th Anniversary logo and your watch's individual edition number, and each piece arrives in a special presentation box designed around the dial's slit motif.
How long does the charge really last?
Approximately 6 months Caliber E036 is Citizen's new next-generation Eco-Drive movement, and a full redesign of its circuit system is what delivers that. In normal wear it simply stays charged; the year-long reserve is the margin for extended periods in a drawer.
What is the Quick Start function?
It lets the watch begin running rapidly on first exposure to light, rather than requiring a long initial charging period before it starts keeping time.
What is Super Titanium?
It's substantially lighter than stainless steel, highly scratch-resistant and hypoallergenic, and because titanium conducts heat poorly it doesn't feel cold against the skin.
What is Eco-Drive?
Eco-Drive is Citizen's light-powered movement technology, introduced in 1976 as the world's first analogue light-powered watch. A cell beneath the dial converts any light source — sunlight or artificial — into energy stored in a rechargeable cell, so the watch never needs a battery. This model marks the technology's 50th anniversary.
Can I change the bracelet for a strap?
Because the bracelet is integrated into the case design, this watch is intended to be worn on its own Super Titanium bracelet. Fitting a conventional strap isn't practical without disrupting the design. City Chain can advise in-store if you have specific requirements.
Can I swim with this watch?
The case is rated to 50 metres, which covers handwashing, rain and everyday splashes comfortably. Given this is a limited-edition collector's piece, it's worth treating it accordingly rather than using it for swimming.
Will 39.6mm fit my wrist?
39.6mm sits just under the standard 40mm men's size and suits most wrist sizes well. At 9.9mm thick and in lightweight titanium, it wears remarkably slim and light — and the integrated bracelet keeps it sitting close to the wrist.
Is the bracelet adjustable?
Yes. The bracelet can be resized by adding or removing links. City Chain offers complimentary bracelet sizing at any outlet — bring your warranty book along for the service.
What warranty does this watch come with?
The BJ6560-53W comes with a 3-year warranty when purchased from City Chain Singapore, an authorised Citizen retailer. Keep your warranty card and proof of purchase — both are required when submitting the watch for service at any City Chain outlet.
