The Citizen Zenshin CA4610-85X pairs a green dial with a case and bracelet made entirely from Super Titanium™ — Citizen's own titanium, finished with a Duratect surface treatment. The result is roughly 40% lighter than stainless steel and far more scratch-resistant, in the bright natural titanium white finish rather than a coating.
The chronograph measures up to 60 minutes in 1/5-second increments, with a 24-hour display and a date positioned between 4 and 5 o'clock — an unusual placement that keeps the hour markers uninterrupted. The dial runs without numerals, relying on luminous indices and hands for a clean, technical read.
Powering it is Citizen's Caliber B620 Eco-Drive, charged by any light with roughly 9 months of reserve — an unusually long one — and no battery, ever. Sapphire glass protects the dial, a screw-down crown and case back seal the case, and it's water resistant to 100 metres. 42.5mm across, 11.6mm thick.

Why You'll Love It
- Super Titanium™ is roughly 40% lighter than stainless steel, and Duratect surface treatment makes it substantially more scratch-resistant. On a 42.5mm chronograph with a full bracelet, that weight difference is felt immediately.
- This is the bright natural titanium finish rather than a dark coating — the material's own colour, which pairs distinctively with the green dial.
- A green dial is a genuine point of difference in a category dominated by black, white and blue, without being loud.
- Approximately 9 months of power reserve is unusually long — this keeps running through extended stretches unworn without needing attention.
- The date sits between 4 and 5 o'clock rather than replacing a marker at 3, so the dial's symmetry stays intact.
- Sapphire glass is significantly harder and more scratch-resistant than mineral crystal, so the dial stays clear for years.
- No battery, ever. Eco-Drive converts any light — sunlight or an office lamp — into the energy that runs the watch.
- A screw-down crown and case back with 100 metres of water resistance means it genuinely handles swimming and snorkelling.

Frequently Asked Questions
What is Super Titanium™?
It's Citizen's proprietary titanium, treated with their Duratect surface-hardening process. The result is roughly 40% lighter than stainless steel and substantially more scratch-resistant — so a large chronograph like this wears far lighter than its size suggests and holds its finish for years.
Does titanium feel different from steel?
Yes, noticeably. It's substantially lighter, and because titanium conducts heat poorly it doesn't feel cold when you first put it on or warm up in the sun the way a steel watch does. It's also hypoallergenic, which suits anyone sensitive to steel alloys.
Where is the date window?
Between 4 and 5 o'clock, rather than the more common 3 o'clock position. It keeps the marker layout symmetrical, since no hour index needs to be removed to make room for it.
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 up to 60 minutes in 1/5-second increments, using the sub-dials to track the total.
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. An Insufficient Charge Warning alerts you before the reserve runs out.
Can I swim with this watch?
Yes. At 100 metres (10 ATM) with a screw-down crown and case back, it's rated for swimming and snorkelling. It isn't 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 42.5mm fit my wrist?
42.5mm runs larger than the standard 40mm men's size and suits medium to larger wrists best. The titanium construction makes a real difference though — it wears far lighter than a steel watch of the same size, so the proportions feel less imposing on the wrist than the number suggests.
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 CA4610-85X 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.
