The Citizen NJ0243-06A is a classic dress-watch take on the automatic, evoking the warmth of a vintage study. A champagne-toned dial carries applied indices supplemented by Roman numerals at 12 and 6 o'clock, framed by a rose gold-tone case — restrained, minimal styling with genuine warmth.
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, an attractive detail at this price point. A small date window sits at 3 o'clock for everyday practicality.
The 40mm rose gold-tone stainless steel case runs a slim 11.6mm thick, finished on a dark brown calf leather strap with a fold-over clasp and push button. Mineral glass protects the dial, and the case is water resistant to 50 metres.

Why You'll Love It
- The champagne dial and rose gold-tone case give this a warm, vintage-study character that stands apart from the usual black-and-steel automatic.
- Roman numerals at 12 and 6 o'clock, paired with applied indices elsewhere, give the dial a restrained, classic touch without feeling cluttered.
- An exhibition caseback lets you watch the automatic movement in action — a genuinely attractive detail at this price point.
- Calibre 8210 is a real automatic movement: no battery, wound by the motion of your wrist, with the mechanical character that appeals to enthusiasts moving up from quartz.
- Deliberately minimal — no unnecessary complications or sub-dials cluttering the face, just clean time-and-date functionality with genuine mechanical charm.
- At 40mm and a slim 11.6mm, it sits comfortably under a cuff and reads as a proper dress watch rather than a sports piece.
- The dark brown leather strap softens the whole look, making this an easy transition piece between the boardroom and the weekend.
- 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.
Is the case solid gold?
No. The case is rose gold-tone stainless steel — a gold-toned finish over steel, giving the warmth and colour of gold with the durability and price of a steel watch.
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. At just 11.6mm thick and 62 grams, it sits especially slim and light for an automatic.
Is the strap adjustable?
Yes. The calf leather strap can be resized by adjusting the buckle position, and City Chain can fit a replacement strap in-store if the original wears out over time.
What warranty does this watch come with?
The NJ0243-06A 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.
