The Citizen AW0151-85E is an Eco-Drive — powered by light instead of a battery. Any light source, indoor or outdoor, keeps the movement running, and a full charge holds for approximately 6 months in the dark. No battery to replace, no service visit for that reason, ever.
The dial is a black, textured finish with clean line indices, set in a 40.5mm stainless steel case at 10.4mm thick, paired with a matching stainless steel bracelet on a folding safety clasp. A day/date display sits in an unusual split layout — day at 12 o'clock, date at 6 o'clock — rather than the single sub-dial most watches use.
Inside is Citizen's Caliber J800, accurate to within roughly 15 seconds a month. Mineral glass protects the dial, and the case is water resistant to 100 metres — 117 grams on the wrist.

Why You'll Love It
- No battery, ever. Eco-Drive converts any light — sunlight or an office desk lamp — into the energy that runs the watch, so there's no dead-battery surprise and no battery-replacement visit.
- A full charge holds for approximately 6 months with no light at all. Ordinary daily wear keeps it topped up indefinitely.
- The day/date layout is genuinely different — day at 12 o'clock, date at 6 o'clock — instead of the single date window most watches default to. It reads more like a small-complication dress watch than a standard three-hander.
- Caliber J800 holds accuracy to roughly 15 seconds a month, well within what you'd expect from a quality quartz movement.
- A textured black dial with clean line indices reads formal and versatile — dark enough for the office, understated enough for everyday wear.
- An all-steel case-and-bracelet build gives this real everyday durability that a leather strap can't match, with a folding safety clasp that stays secure.
- An Insufficient Charge Warning and Overcharge Prevention function protect the movement automatically — the watch manages its own charge, you don't have to think about it.
- 100m water resistance gives real everyday margin against rain, splashes and handwashing.

Frequently Asked Questions
What is Eco-Drive?
Eco-Drive is Citizen's light-powered movement technology. A cell beneath the dial converts any light source — sunlight, a lamp, an overhead office light — into energy stored in a rechargeable cell, so the watch never needs a battery. Wear it normally with occasional light exposure and it stays charged indefinitely.
How long does the charge last if I stop wearing it?
Approximately 6 months from a full charge with no further light exposure. If the reserve runs low, an Insufficient Charge Warning function alerts you so you can put it back in the light before it stops. A short session in direct sunlight or under a bright lamp restores charge quickly.
How does the day and date display work?
The day of the week shows in a window at 12 o'clock and the date shows at 6 o'clock — a split layout rather than the single date window most watches use. Both are set via the crown; if you're unsure how, any City Chain outlet can walk you through it.
How accurate is this watch?
Caliber J800 is rated to approximately ±15 seconds per month — typical for a quality quartz movement and considerably steadier than a mechanical watch.
Can I swim or shower with this watch?
The case is rated to 100 metres, which covers handwashing, rain, everyday splashes and swimming comfortably. It's not designed for diving.
Does an Eco-Drive watch need servicing?
Far less than a mechanical watch — there's no mainspring or balance assembly to wear in the same way. The rechargeable cell is designed to last many years under normal use. Bring it to any City Chain outlet if you notice reduced charge retention over time.
Will 40.5mm fit my wrist?
40.5mm sits comfortably in the standard men's range and suits most wrist sizes. At 10.4mm thick and 117 grams, it has a reassuring, solid feel on the wrist without being heavy.
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 AW0151-85E 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.
