The Citizen CA4677-50H is a sport chronograph built around contrast: a black dial with three sub-dials carrying blue accents, set in a grey-plated stainless steel case. The blue detailing does real work — it separates the sub-dials from the dial around them, so the chronograph stays readable rather than disappearing into a wall of black.
A tachymeter scale runs around the bezel for calculating speed over a known distance, and the date sits between 4 and 5 o'clock rather than replacing a marker at 3 — a placement that keeps the dial's symmetry intact. A 24-hour display makes AM/PM unambiguous.
Sapphire crystal protects the dial — noticeably harder and more scratch-resistant than the mineral glass common in this category. The 43mm case is 11.3mm thick and the watch weighs 145 grams on its matching bracelet, water resistant to 100 metres. Citizen's Caliber E620 Eco-Drive runs on any light source, so there's no battery to replace, ever.

Why You'll Love It
- Blue accents on the three sub-dials give the black dial genuine depth and make the chronograph registers easy to pick out — a functional touch as much as a styling one.
- The grey-plated case and bracelet is a real point of difference against the usual polished steel or all-black finishes, and it hides everyday marks better than a mirror polish.
- Sapphire crystal is significantly harder and more scratch-resistant than the mineral glass used on most chronographs at this price, so the dial stays clear for years.
- The tachymeter scale lets you calculate average speed over a known distance — a genuine motorsport-derived function.
- The date sits between 4 and 5 o'clock, so no hour marker has to be removed to make room for it and the dial stays symmetrical.
- A 24-hour display makes AM/PM unambiguous at a glance, which is useful when travelling.
- No battery, ever. Eco-Drive converts any light — sunlight or an office lamp — into the energy that runs the watch, which matters more on a chronograph than a simple three-hander.
- 100 metres of water resistance means it genuinely handles swimming, not just splashes.

Frequently Asked Questions
What colour is the dial?
The dial is black, with blue accents on the three chronograph sub-dials. The grey is the case and bracelet finish — grey-plated stainless steel — which gives the watch its contemporary look against the darker dial.
What does the tachymeter do?
A tachymeter calculates average speed over a known distance. Start the chronograph at the beginning of a measured kilometre or mile, stop it at the end, and read your average speed off the scale on the bezel. The bezel is fixed rather than rotating.
Where is the date window?
Between 4 and 5 o'clock, rather than the more common 3 o'clock position. It keeps the dial symmetrical, since no hour marker 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. The three sub-dials track elapsed time while the main hands continue showing the time as normal.
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.
Do I need to charge it deliberately?
No. Normal daily wear gives it more than enough light — through a shirt cuff, under office lighting, or outdoors. If it has been stored in the dark for a long period, a few hours in daylight brings it back, and an Insufficient Charge Warning alerts you before the reserve runs out.
Is the crystal sapphire?
Yes. Sapphire is significantly harder and more scratch-resistant than the mineral glass used on most chronographs at this price, so the dial stays clear through years of daily wear.
Can I swim with this watch?
Yes. At 100 metres (10 BAR) it's rated for swimming and snorkelling. It isn't designed for diving.
Will 43mm fit my wrist?
43mm runs larger than the standard 40mm men's size and suits medium to larger wrists best. At 11.3mm thick it's reasonably slim for a chronograph, though at 145 grams on the bracelet it has genuine weight and presence.
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.

The CA4677-50H 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.
