The Citizen PR1040-88N is a limited edition from the Beginning Blue collection, built around a blue mother of pearl dial that catches light with a natural iridescent shimmer. Mother of pearl is cut from the inner layer of shell, so every dial carries its own pattern — no two pieces are alike.
An open-heart aperture at 7 o'clock opens a window into the movement, so you can watch the balance wheel oscillating as the watch runs. That movement is Caliber 6628, a 21-jewel automatic wound by the motion of your wrist with a 40-hour power reserve — no battery, ever.
The 28.5mm polished stainless steel case is 9.9mm thick, with silver-tone indices, luminous hands and a matching steel bracelet. Sapphire glass protects the dial — noticeably harder and more scratch-resistant than the mineral crystal common at this size — and the case is water resistant to 50 metres.

Why You'll Love It
- The open-heart aperture at 7 o'clock lets you watch the balance wheel oscillating — the beating heart of a mechanical watch, visible from the dial side rather than hidden behind the case.
- Mother of pearl is a natural material, so every dial has its own pattern and shifts with the light. No two watches in the edition are quite identical.
- A mechanical movement in a 28.5mm women's watch is genuinely uncommon — most watches this size are quartz, so this is a real point of difference for anyone who appreciates traditional watchmaking.
- 21 jewels and a 40-hour power reserve mean it keeps running for well over a day after you take it off, and regular wear keeps it wound indefinitely.
- No battery, ever. The movement winds itself from the natural motion of your wrist.
- Sapphire glass is significantly harder and more scratch-resistant than the mineral crystal used on most watches at this size, so the dial stays clear for years.
- At 28.5mm and 9.9mm thick, it's proportioned to wear delicately while still having the substance a mechanical movement gives it.
- Luminous hands keep it readable in low light — a practical touch on a dress watch.

Frequently Asked Questions
What is an open-heart dial?
An aperture cut into the dial — here at the 7 o'clock position — that exposes part of the movement beneath. You can watch the balance wheel oscillating back and forth as the watch runs, which is the visible sign of a mechanical movement keeping time.
What is a mother of pearl dial?
Mother of pearl is the natural iridescent lining found inside certain shells. Cut into thin slices and used as a dial, it produces a soft, shifting shimmer that changes with the light and viewing angle. Because it's a natural material, the pattern varies from piece to piece — your dial won't be identical to anyone else's.
What does "automatic" mean?
An automatic watch is powered by the natural movement of your wrist. A rotor inside the case winds the mainspring as you wear it, so no battery is needed. If left unworn for around a day and a half it will stop and need resetting — simply wear it again to restart it.
How long does the power reserve last?
40 hours when fully wound, so it keeps running for well over a day after you take it off. Regular daily wear keeps it continuously wound.
How accurate is a mechanical watch?
Mechanical movements aren't as precise as quartz by design — expect to reset the time every week or two. The appeal is the craftsmanship, the visible movement through the open heart, and the fact it never needs a battery.
Does a mechanical watch need servicing?
Yes. Unlike a quartz watch, an automatic has moving parts and lubricants that wear over time. Citizen recommends periodic servicing to keep timekeeping and water resistance within spec. Any City Chain outlet can arrange this — bring your warranty card.
Is the glass sapphire?
Yes. Sapphire is significantly harder and more scratch-resistant than the mineral crystal used on most watches at this size and price, so the dial stays clear through years of daily wear.
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.
Will 28.5mm fit my wrist?
28.5mm is a classic, delicate women's case size and suits most wrist sizes comfortably. At 9.9mm thick it has a little more presence than a quartz watch of the same diameter, which is what accommodates the mechanical movement inside.
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 PR1040-88N 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.
