The Citizen Attesa AT8384-58E marks 50 years of Eco-Drive with a watch that turns the technology's hardest problem into its centrepiece. Black dials are traditionally difficult for light to penetrate — a genuine obstacle for a light-powered movement. This one showcases advanced dial engineering that absorbs light across even the darkest surfaces, so a deep black dial powers the watch as reliably as a pale one. Limited to 2,200 unnumbered pieces worldwide.
The case is 42mm Super Titanium™ with a grey Duratect DLC coating and Duratect Amber Yellow gold-tone detailing — a striking all-black build lifted by warm gold contrast. Super Titanium is significantly lighter than stainless steel and far harder than untreated titanium, so it wears comfortably all day and resists the scratches that dull a steel case. It's also metal-allergy resistant and rated to JIS Class 1 magnetic resistance.
Inside is Calibre H800 with Atomic Timekeeping — automatically syncing to radio time signals across four regions (Japan, China, the USA and Europe) — plus a chronograph, world time across 26 zones, a perpetual calendar with day and date, 12/24-hour display, and a power reserve indicator. Accurate to ±15 seconds a month even without radio reception. Sapphire crystal with Clarity Coating, water resistant to 100 metres.

Why You'll Love It
- The black dial is a genuine engineering achievement, not just a colour choice — black surfaces are traditionally hard for light to penetrate, and this dial absorbs enough to power the movement reliably. It's a demonstration piece for Eco-Drive's 50th anniversary.
- Limited to 2,200 unnumbered pieces worldwide — a genuinely scarce anniversary release, the smallest edition of the LIGHT in BLACK Eco-Drive anniversary pieces.
- Super Titanium™ is roughly 40% lighter than stainless steel while being considerably harder — so a 42mm chronograph wears comfortably all day rather than weighing on the wrist.
- Duratect DLC surface hardening resists the everyday scratches and scuffs that dull a conventional case finish, keeping the black looking deliberate rather than worn.
- Atomic Timekeeping syncs automatically to radio signals across four regions — Japan, China, the USA and Europe — so the time corrects itself wherever you travel.
- Even outside radio coverage it holds ±15 seconds a month, and a power-save mode extends the reserve to roughly 10 months.
- The complication stack is genuinely complete: chronograph, world time across 26 zones, perpetual calendar with day and date, 12/24-hour display and a power reserve indicator.
- Metal-allergy resistance and JIS Class 1 magnetic resistance make this practical for daily wear in ways most dress chronographs aren't.

Frequently Asked Questions
How can a black dial power an Eco-Drive watch?
That's exactly the point of this piece. Black surfaces are traditionally difficult for light to penetrate, which makes them a challenge for light-powered movements. This watch uses advanced dial engineering that enables light absorption even across very dark surfaces, so it charges reliably — a technical demonstration released to mark 50 years of Eco-Drive.
What makes this a limited edition?
It's produced to a fixed run of 2,200 unnumbered pieces worldwide, released for the 50th anniversary of Eco-Drive. Once that run sells through, this configuration won't be reproduced.
What is Super Titanium™?
Citizen's proprietary titanium, treated with its Duratect surface-hardening process. It's roughly 40% lighter than stainless steel and considerably harder than untreated titanium, so it resists scratches while staying comfortable on the wrist. It's also hypoallergenic, making it suitable for sensitive skin.
What does Duratect DLC mean?
DLC stands for diamond-like carbon — a hard surface coating applied over the Super Titanium case. It gives the watch its deep grey-black finish while adding significant scratch resistance beyond the titanium itself.
What is Atomic Timekeeping?
The watch receives radio time signals broadcast from atomic clocks and corrects itself automatically. This model syncs across four regions — Japan, China, the USA and Europe — so it stays accurate as you travel. Outside coverage it keeps time to approximately ±15 seconds per month.
What is a perpetual calendar?
A perpetual calendar automatically accounts for months of different lengths and leap years, so the date and day displays stay correct without you ever manually adjusting them at month-end.
How long does the charge last if I stop wearing it?
In power-save mode the watch runs for approximately 10 months without further light exposure. Returning it to any light source recharges it — there's no battery to replace at any point.
Is this suitable for sensitive skin?
Yes. The Super Titanium case and bracelet are metal-allergy resistant, which makes this a genuine option for wearers who react to stainless steel or nickel-containing alloys.
Can I swim with this watch?
The case is rated to 100 metres, which comfortably covers handwashing, rain, everyday splashes and swimming. It's not designed for diving.
Will 42mm fit my wrist?
42mm runs slightly larger than the standard 40mm men's size and suits medium to larger wrists. That said, Super Titanium is substantially lighter than steel, so it wears far more comfortably than a 42mm steel chronograph would — and at 10.8mm thick it stays slim for its complication count.
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 AT8384-58E 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.
