The Citizen xC EW2638-56Z is a compact, refined everyday watch from Citizen's women's line — 28mm across and just 8.6mm thin, sized to sit lightly on the wrist and slip easily under a sleeve. It's built around sapphire crystal, a material usually reserved for watches well above this price and meaningfully more scratch-resistant than the mineral glass most watches at this size use.
Inside is Citizen's Calibre E011 Eco-Drive movement, charged by any light source — natural or artificial — so it never needs a battery replacement. A full charge holds for approximately 6 months in complete darkness, with an Insufficient Charge Warning that alerts you before the reserve runs low and Overcharge Prevention protecting the cell over the long term.
A date display keeps it practical for daily wear, and 50-metre water resistance covers handwashing, rain and everyday splashes without a second thought. Finished on a stainless steel bracelet — a watch designed to be worn constantly and thought about rarely.

Why You'll Love It
- Sapphire crystal is a genuine step up at this size and price — significantly harder and more scratch-resistant than the mineral glass found on most compact women's watches, so the dial stays clear for years.
- No battery, ever. Eco-Drive converts any light — sunlight or an office desk lamp — into the energy that runs the watch, eliminating dead-battery surprises and replacement visits entirely.
- A full charge holds for approximately 6 months with no light at all, so it keeps running through long stretches in a drawer or jewellery box.
- At 28mm and just 8.6mm thin, it's genuinely delicate on the wrist — sized to wear like jewellery rather than as a statement piece.
- The Insufficient Charge Warning gives you notice before the reserve runs out, and Overcharge Prevention protects the cell over years of ownership. The watch manages itself.
- A date display adds everyday practicality without cluttering a small dial.
- 50-metre water resistance covers handwashing, rain and everyday splashes — no need to take it off at the sink.
- An all-steel case and bracelet gives real everyday durability, suited to constant wear rather than occasional outings.

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 alerts you so you can return it to the light before it stops. A short session in direct sunlight or under a bright lamp restores the charge quickly.
What's the difference between sapphire and mineral glass?
Sapphire crystal, used here, is significantly harder and more scratch-resistant than the mineral glass found on most watches in this size and price range, so the dial stays clearer for longer with everyday wear.
Will 28mm fit my wrist?
28mm is a classic, delicate women's case size and suits most wrist sizes comfortably. At just 8.6mm thick it sits slim and light, and works well worn alongside bracelets or other jewellery.
Can I swim or shower with this watch?
The case is rated to 50 metres, which covers handwashing, rain and everyday splashes comfortably. It's not intended for swimming, showering or 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.
Is the bracelet adjustable?
Yes. City Chain offers complimentary bracelet sizing at any outlet — bring your warranty book along for the service.

The EW2638-56Z 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.
