The Citizen NJ0210-56A pairs a clean white dial with a distinctive touch — blue hands that stand out against the light face. Serif Arabic numerals and an outer minute track give the dial a slightly vintage, field-watch-adjacent character, with a date window sitting neatly at 3 o'clock.
Inside is Citizen's Calibre 8210 automatic movement — 21 jewels, 21,600 vibrations per hour, roughly 40 hours of power reserve. An exhibition caseback shows the movement in motion, a detail more often found on watches well above this price. The 40mm stainless steel case pairs with a matching stainless steel bracelet on a folding clasp.
Mineral glass protects the dial front and back, and the case is water resistant to 50 metres.

Why You'll Love It
- The blue hands against the white dial are a genuine point of difference — a small detail that gives this watch more character than a standard black-on-white dial layout.
- Serif Arabic numerals and an outer minute track give the dial a slightly vintage, field-watch-adjacent look, distinct from a plain modern dress dial.
- An exhibition caseback lets you watch the automatic movement in action — a feature usually reserved for watches well above this price point.
- Calibre 8210 is a genuine automatic movement: no battery, wound by the motion of your wrist, with the mechanical character that appeals to enthusiasts moving up from quartz.
- A date window at 3 o'clock keeps it functional for daily use — you don't have to choose between mechanical character and everyday practicality.
- The matching stainless steel bracelet gives this genuine everyday durability and a clean, cohesive look that a leather strap can't match.
- At 40mm, it sits comfortably under a cuff without reading as oversized.
- No battery, ever. The movement runs on the motion of daily wear, so there's nothing to replace.

Frequently Asked Questions
Can I see the movement?
Yes. The caseback is an exhibition window, so the automatic movement is visible from the back of the watch while it's running.
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 about two days it will stop and need resetting — simply wear it again to restart it.
How long does the power reserve last?
Approximately 40 hours when fully wound, so the watch keeps running for close to two days after you take it off. Regular daily wear keeps it continuously wound.
How accurate is a mechanical watch?
Mechanical movements are not as precise as quartz by design — expect to reset the time every week or two. The appeal is the engineering and the absence of a battery rather than chronometer-level accuracy.
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.
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.
Will 40mm fit my wrist?
40mm sits in the middle of the modern men's range and suits most wrist sizes from roughly 15cm to 19cm.
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 NJ0210-56A 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.
