The Citizen NJ0158-89L Tsuyosa is a worldwide limited edition of 1,999 pieces, built around a dial colour developed with Pantone. Citizen calls it Glowing Blue, and the name is earned — the sunray finish makes it read as a bright azure in daylight and a deeper petrol blue as the light drops, so the dial does not look the same at nine in the morning as it does at six in the evening.
This is the blue that a standard Tsuyosa cannot give you. The open-production models use conventional sunray blues; this one was colour-matched for the collaboration and appears on no other reference in the range.
Underneath it is the Tsuyosa formula that made the collection work. Citizen's Calibre 8210 automatic with 21 jewels and a 42-hour power reserve, on display through the skeleton caseback. Sapphire crystal with a cyclops lens over the 3 o'clock date. A seamlessly integrated stainless steel bracelet with a fold-over push-button clasp. 40mm across, 11.7mm thick, 139 grams, 50-metre water resistance.

Why You'll Love It
- Limited to 1,999 pieces worldwide. Citizen produces the standard Tsuyosa in open runs — the Pantone editions are the exception, and once the allocation is gone it does not come back.
- Glowing Blue is exclusive to this reference. It was colour-matched for the Pantone collaboration and is not used on any other Tsuyosa, so you will not see it on another wrist in the collection.
- The sunray finish gives it genuine range — bright azure under daylight, deeper and more petrol-toned in the evening. It is the same watch reading two different ways depending on when you look at it.
- Blue is the safest colour to commit to on a limited edition. Unlike a novelty dial you eventually tire of, this one still works with a suit, with denim and with everything in between.
- The integrated bracelet flows straight out of the case with no visible lugs, giving a single continuous line that makes 40mm wear more refined than the measurement suggests.
- At 11.7mm thick and 139 grams it is slim and light for a full-bracelet automatic, so it sits flat under a cuff instead of catching on it.
- The skeleton caseback puts the Calibre 8210 and its oscillating rotor on display — mechanical watchmaking you can watch, on a piece that will not be produced again.

Key Features

Frequently Asked Questions
How limited is this edition?
1,999 pieces worldwide, across all markets combined. The rest of the Tsuyosa range is open production, so the Pantone references are the only ones with a fixed run. Singapore receives a share of that global allocation, and once it sells through there is no restock.
What is Glowing Blue?
It is the Pantone colour Citizen selected for this limited edition. On the wrist the sunray brushing makes it read as a bright, luminous azure in daylight and settle into a deeper petrol blue indoors or in the evening. It is more vivid than the blues used on the standard Tsuyosa models, and it appears on no other watch in the range.
Which Pantone Tsuyosa should I choose?
Each is a separate limited edition of 1,999 pieces sharing the same 40mm case, Calibre 8210 and skeleton caseback — only the dial changes. The NJ0158-89L is Glowing Blue, the most versatile of the set. The NJ0158-89Y is Warm Sand, a soft neutral beige. Browse the full Citizen Tsuyosa collection.
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, or wind the crown manually to restart it.
Can I wind this watch by hand?
Yes. The Calibre 8210 supports manual winding as well as automatic winding. If the watch has stopped, turn the crown clockwise around 20 to 30 times to get it running, then wear it normally to keep it wound.
How long does the power reserve last?
Approximately 42 hours when fully wound, so the watch keeps running for the better part of two days after you take it off. Regular daily wear keeps it continuously wound.
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, the NJ0158-89L is rated for handwashing, rain and brief accidental splashes, but it is not intended for swimming, showering or diving. If you need a Tsuyosa you can swim in, the Tsuyosa Shore models are rated to 100 metres.
Is the bracelet adjustable?
Yes. The stainless steel 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.
Is this a good gift?
A limited edition makes an unusually strong gift because the recipient knows it cannot simply be bought again. This one pairs that with the most wearable dial colour in watchmaking and the substance of sapphire crystal, an automatic movement and a skeleton caseback. Well suited to milestone birthdays, anniversaries and retirements.
What warranty does this watch come with?
The NJ0158-89L 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.
