The Citizen NJ0210-13L is built around one decision: a striking blue dial in place of the usual black or silver. Set against a 40mm stainless steel case, it's the colour that carries the whole watch — elegant hands sweep across it with a quiet, dressy character.
Inside is Citizen's Calibre 8210 automatic movement — 21 jewels, 21,600 vibrations per hour, roughly 40 hours of power reserve. A date display keeps it practical for daily wear. Mineral glass protects the dial, the case runs 13mm thick, and the whole piece is finished on a calf leather strap with water resistance to 50 metres.

Why You'll Love It
- The blue dial is the entire point. Where most automatics default to black or silver, this one leads with colour — distinctive on the wrist without tipping into loud.
- 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 keeps it functional for daily use — you don't have to choose between mechanical character and everyday practicality.
- At 40mm and a moderate weight, it sits comfortably under a cuff without reading as oversized.
- Mineral glass keeps the dial protected against everyday scuffs while keeping the watch accessible at this price point.
- The calf leather strap softens the whole look, making this an easy transition piece between office and evening wear.
- No battery, ever. The movement runs on the motion of daily wear, so there's nothing to replace.

Frequently Asked Questions
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 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 NJ0210-13L 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.
