The Citizen NJ0158-89Y Tsuyosa is a worldwide limited edition of 1,999 pieces — the only limited-run model in the Tsuyosa line, and the reason this one is worth moving on rather than thinking about.
The dial is Warm Sand: a soft sunray beige with a golden cast that shifts between pale cream and deeper sand as the light moves. It is not a colour Citizen uses elsewhere in the range, and it is considerably more subtle than a photograph suggests — closer to a neutral than to a statement, which is what makes it wearable beyond the novelty of owning a limited edition.
Everything underneath is the Tsuyosa formula that made the collection work. Citizen's Calibre 8210 automatic with 21 jewels and a 42-hour power reserve, visible 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 — this is the exception, and once the allocation is gone it does not come back.
- Warm Sand is exclusive to this reference. Nothing else in the Tsuyosa range uses it, so the dial is not something you will see on another wrist in the collection.
- The sunray finish gives the sand tone real movement — it lifts toward cream in direct light and settles into a deeper golden beige indoors, which stops it reading as flat or washed out.
- It behaves like a neutral. Sand pairs with navy, charcoal, brown leather and denim without any thought, so unlike most limited editions you can actually wear this one daily.
- 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

- Warm Sand sunray dial — a soft golden beige with a sunray brushed finish that shifts tone with the light, exclusive to this reference.
- Sapphire crystal with cyclops lens — rated 9 on the Mohs hardness scale, with a magnifying lens over the 3 o'clock date window.
- Skeleton caseback — transparent caseback showing the Calibre 8210 and its oscillating rotor in motion.
- 40mm stainless steel case — 11.7mm thick with a polished finish and a fixed silver-tone bezel, weighing 139 grams on the bracelet.
- Integrated stainless steel bracelet — flows directly from the case with no visible lugs, secured by a fold-over clasp with push-button release.

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 this is the only reference in the collection with a fixed run. Singapore receives a share of that global allocation, and once it sells through there is no restock.
What colour is Warm Sand?
A soft golden beige — closer to sand or light champagne than to yellow or gold. The sunray brushing lifts it toward cream in direct light and lets it settle into a deeper tone indoors. It reads as a neutral rather than a colour dial, which is why it pairs easily with navy, charcoal, brown leather and denim.
Is this part of a collaboration?
This reference is issued as a Tsuyosa limited edition tied to Citizen's Pantone colour collaboration. The Warm Sand dial is exclusive to it and is not used on any other watch in the Tsuyosa range.
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 NJ0158-89Y 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 adds a dial colour that works with everything 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 NJ0158-89Y 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.
