The Citizen NJ0191-83M takes Citizen's proven entry-level automatic platform and gives it two things that set it apart: a bright light blue dial, and Citizen's Blue Glow Night luminous treatment — the hands and markers glow blue in the dark rather than the conventional green.
The dial carries luminous dots and stick markers with a date display at 3 o'clock, set in a 40mm stainless steel case on a matching bracelet. A see-through exhibition caseback reveals the Calibre 8210 automatic movement at work — 21 jewels, 21,600 vibrations per hour, and roughly 40 hours of power reserve, all wound by the natural motion of your wrist.
The specification that genuinely matters here is 100 metres of water resistance — double what most watches in this segment offer, and enough for swimming. At 12.2mm thick and 160 grams, it has real substance on the wrist, protected by mineral crystal and closing on a fold-over clasp with push-button release.

Why You'll Love It
- Blue Glow Night is Citizen's own luminous treatment — the hands and markers glow blue in darkness rather than the usual green, which is genuinely uncommon and instantly recognisable.
- The light blue dial is a real point of difference in a segment dominated by black, white and navy — bright and fresh without being loud.
- 100 metres of water resistance is double what most entry-level mechanical watches offer, and enough for swimming rather than just splashes.
- The see-through exhibition caseback lets you watch the Calibre 8210 working — the rotor swinging, the balance wheel oscillating. It's what makes owning a mechanical watch tangible.
- Calibre 8210 is a proven Citizen workhorse: 21 jewels, 21,600 vibrations per hour, and roughly 40 hours of reserve. Not exotic, but genuinely reliable and serviceable.
- No battery, ever. The movement winds itself from the motion of your wrist.
- At 160 grams on a full steel bracelet, it has real presence and heft — this feels like a substantial watch rather than a lightweight one.
- Luminous dots and stick markers with a date window at 3 o'clock keep the dial genuinely legible day or night.

Frequently Asked Questions
What is Blue Glow Night?
It's Citizen's own luminous treatment, where the hands and hour markers glow blue in darkness rather than the conventional green most watches use. It's a distinctive touch that makes the watch instantly recognisable at night.
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 two days it will stop and need resetting — simply wear it again to restart it.
Can I see the movement?
Yes. The caseback is a see-through exhibition window, so you can watch the Calibre 8210 working — the rotor swinging as you move and the balance wheel oscillating.
How long does the power reserve last?
Approximately 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.
Can I swim with this watch?
Yes. At 100 metres (10 BAR) water resistance, this is rated for swimming and general water activities — double the rating of most entry-level mechanical watches. It isn't designed for diving.
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 engineering, the exhibition caseback, 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.
Will 40mm fit my wrist?
40mm sits right in the middle of the modern men's range and suits most wrist sizes from roughly 15cm to 19cm. At 12.2mm thick and 160 grams it wears with genuine substance rather than feeling light.
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 NJ0191-83M 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.
