The Citizen CA4630-53X is a classic three-register chronograph in a green dial — a colour that reads considerably more distinctive than the black and silver that dominate this category, without being loud. Three sub-dials including a 24-hour indicator sit within a 42mm stainless steel case on a matching bracelet.
The chronograph measures to 1/5 of a second, and the seconds hand sweeps smoothly rather than ticking — a genuinely satisfying detail to watch in operation. A date display and low-charge indicator round out the practical functions.
Powering it is Citizen's Caliber B620 Eco-Drive movement, charged by any light source with approximately 9 months of power reserve from a full charge — no battery replacement, now or ever. Mineral glass protects the dial, and the case is water resistant to 50 metres, closing on a deployant clasp.

Why You'll Love It
- A green dial gives this real character in a category dominated by black and silver — distinctive without being attention-seeking, and it pairs naturally with steel.
- The chronograph seconds hand sweeps smoothly rather than ticking, measuring to 1/5 of a second — a genuinely satisfying thing to watch in operation.
- Approximately 9 months of power reserve from a full charge is unusually long — this keeps running through extended stretches unworn without needing attention.
- No battery, ever. Eco-Drive converts any light — sunlight or an office lamp — into the energy that runs the watch, so there's no dead-battery surprise and no replacement visit.
- Three sub-dials including a 24-hour indicator give the dial genuine chronograph presence and real functionality, not just decorative registers.
- A low-charge indicator tells you when the reserve is running down, so the watch effectively manages itself.
- At 42mm with a 13mm profile on a steel bracelet, it has proper chronograph substance on the wrist.
- Everything about it is designed to be worn and forgotten about — no winding, no battery, no fuss.

Frequently Asked Questions
How does the chronograph work?
The chronograph is a stopwatch built into the watch, operated by the pushers beside the crown. It measures elapsed time to 1/5 of a second, and the chronograph seconds hand sweeps smoothly rather than ticking — which is both more precise to read and more satisfying to watch.
What is the 24-hour sub-dial for?
It shows the time on a 24-hour scale, which makes it easy to tell at a glance whether the time is AM or PM — useful when travelling, or simply as a secondary reference.
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.
How long does the charge last if I stop wearing it?
Approximately 9 months from a full charge with no further light exposure — unusually long, even among Eco-Drive watches. A low charge indicator warns you as the reserve runs down, and a short session in daylight restores it.
Can I swim with this watch?
No. With 50-metre (5 BAR) water resistance it's rated for handwashing, rain and brief accidental splashes, but it isn't 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.
Will 42mm fit my wrist?
42mm runs slightly larger than the standard 40mm men's size and suits medium to larger wrists well. At 13mm thick it has genuine chronograph presence, which is typical for a three-register watch of this type.
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 CA4630-53X 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.
