The Citizen Tsuyosa NJ0150-81E gives you a green sunburst dial, Citizen’s own automatic movement, and 50m water resistance for a street price that usually sits around $175–$225. At that money, it’s one of the best value automatics you can buy right now.
For anyone who wants a distinctive daily wearer without crossing $250, the Tsuyosa Green covers nearly every box.
The trade-offs are real but minor: a mineral Hardlex crystal and a movement that doesn’t hack. Neither is a dealbreaker at this price.
Overview
Citizen launched the Tsuyosa in 2021 as an accessible way into its automatic catalogue, and the name means “strength” in Japanese. The NJ0150 family runs across navy, silver, champagne, and this hunter green, all on the same 40mm case and Caliber 8210 movement.
The Tsuyosa also filled a real gap. Citizen had long owned the affordable solar Eco-Drive space but offered little here for buyers who specifically want a mechanical rotor they can watch through the caseback. For the wider lineup, our best Citizen watches guide covers both Eco-Drive and automatic options.

Design & Dial
The green dial is the whole reason to buy this watch. Under different light it shifts from deep forest green to an almost teal tone, and the sunburst finish does the heavy lifting. It punches well above its price.
Applied silver-tone indices and baton hands keep the layout clean and legible. Both carry Lumibrite, and owners report two to three hours of usable glow after a charge in direct light.
The date window sits at 3 o’clock, white background, black numerals. Functional, not refined. A colour-matched date disc would look better, but that’s a lot to ask at this price.
A flat Hardlex crystal protects the dial. Citizen’s hardened mineral glass resists scratches better than basic mineral, but it won’t match sapphire for durability.
The 40mm case rides on a three-link oyster-style steel bracelet with a fold-over clasp and push-button release. The standout detail is solid end links, which you rarely see at this price.
Brushed centre links sit against polished outer edges, and the finishing is done neatly. What gets me is how little rattle there is, since cheap links usually give themselves away. Bracelet rattle is minimal.
Movement & Accuracy
Citizen’s Caliber 8210 is a 21-jewel automatic with a bidirectional rotor and hand-winding through the crown. That last part is handy for topping up the 42-hour reserve over a weekend off the wrist.
Citizen rates it at ±15 seconds per day, standard for this class. Plenty of owners report theirs running tighter, closer to ±5–10 seconds per day. Plan around the rated ±15, not the lucky examples.
The exhibition caseback shows off the rotor and bridges, though there’s no decorative finishing here. The movement is built to work, not to be admired. It’s functional, not display-grade.
If you’re curious how far Citizen’s engineering goes, it’s worth seeing the other end of the range. Our guide to the most expensive Citizen watches shows how high the brand climbs above this entry point.
One real limitation: the Caliber 8210 doesn’t hack, so the seconds hand keeps running when you pull the crown to set the time. Syncing to the exact second is fiddlier than with workhorse movements like the Seiko NH35 or Orient’s calibres, which hack as standard.
On the Wrist
At 40mm and about 12mm thick, the Tsuyosa sits easily on most wrists. Owners in the 6.5–7.5 inch range keep calling the proportions just about ideal, big enough to notice, small enough to stay versatile.
The clasp has micro-adjustment, a small thing that matters for daily comfort. And the 20mm lug width opens up a huge aftermarket strap pool if you want a cheap change of pace.
On Watchuseek and Reddit’s r/Watches, the consensus puts the Tsuyosa’s bracelet above similarly priced Seiko 5 models. The solid end links and tighter build come up again and again.
The green dial gets praised for range too. Owners say it reads dressy enough for business-casual but stays proportionate for the weekend. Under incandescent light it goes richer and darker; outdoors it catches a truer green that tends to pull attention.
Pros
- Distinctive sunburst green dial with strong visual presence for the price
- 50m water resistance — safe for recreational swimming, not just handwashing
- 20mm lug width opens a vast aftermarket strap selection
- Exhibition caseback included at sub-$225
- Solid end links on the bracelet, uncommon at this price tier
- Hand-winding capability via the crown
- Lumibrite lume performs reliably for evening readability
Cons
- Mineral Hardlex crystal rather than sapphire — will scratch with heavy daily use
- No hacking seconds hand, making precise time-setting fiddly
- Exhibition caseback reveals a movement with no decorative finishing
- Date disc does not match the green dial aesthetic
- 42-hour power reserve is on the shorter side for an automatic
Who It’s For
This is the right watch for first-time automatic buyers who want something louder than the usual navy or black dial, and for collectors building a colour-dial rotation on a budget. It’s an easy first automatic.
It’s not for buyers who care most about movement finishing, sapphire, or hacking seconds. But for a reliable, good-looking everyday automatic under $225 from an established Japanese maker, it’s hard to fault. New to mechanicals and wondering how long automatics last? With service, decades.
It also makes a strong summer or casual bracelet watch. The green pairs naturally with lighter clothing, and 50m water resistance means poolside afternoons are fine. Strap-swappers are well served by that 20mm lug width.
Alternatives to Consider
Seiko 5 Sports (SNKL / SRPK series): Seiko’s 4R36 movement adds hacking and hand-winding, a clear edge for precise time-setting. The catch is the bracelet, generally rated below the Tsuyosa’s with more taper and rattle, and Seiko 5 prices have climbed a lot since 2020.
Orient Mako III / Ray III: Orient’s in-house movement also hacks and hand-winds, at a similar or lower price. The trade-off is a more utilitarian dive-watch look, where the Tsuyosa stays the more versatile pick across dress and casual.
Citizen NB1060: If you like the Tsuyosa but can stretch the budget, the Citizen NB1060 Silver Leaf steps up in dial artistry and movement spec while staying in the Citizen family. Worth a look if $300–$400 is reachable.
Verdict
The Tsuyosa NJ0150-81E is one of the easiest sub-$250 recommendations I can make. The green sunburst dial genuinely changes character with the light, and the bracelet build beats what the price suggests.
50m water resistance keeps it a real everyday watch, not a weekend novelty. The missing hack and mineral crystal are fair criticisms, but neither kills the deal.
If you want colour, presence, and a dependable mechanical movement from a mainstream Japanese maker, the Tsuyosa Green delivers.
Frequently Asked Questions
Is the Citizen Tsuyosa NJ0150-81E water resistant enough for swimming?
Yes. At 50m (5 ATM) it’s fine for recreational swimming, snorkelling, and showering. Skip the scuba diving and high-impact water sports, but for everyday water exposure the rating is conservative and reliable.
Does the Citizen Tsuyosa NJ0150-81E have a sapphire crystal?
No, it uses Citizen’s Hardlex mineral crystal, which resists scratches better than standard mineral glass but is softer than sapphire. Sapphire is rare below $300 and only becomes a common expectation closer to the $400–$500 range.
What is the lug width of the Citizen Tsuyosa NJ0150-81E?
The lug width is 20mm, one of the most common sizes out there. That means endless aftermarket straps in leather, NATO, rubber, and mesh, so changing the look is cheap and easy without touching the case.
Does the Citizen Tsuyosa hack?
No. The Caliber 8210 doesn’t hack, so the seconds hand keeps running when you pull the crown to set the time, which makes precise syncing harder. It does hand-wind through the crown, which is the more useful feature day to day.
How does the Citizen Tsuyosa compare to a Seiko 5 Sports at a similar price?
The Seiko 5 Sports (4R36) gives you hacking and hand-winding, an edge for precise time-setting. The Tsuyosa answers with a noticeably better bracelet, solid end links, less rattle, more heft, plus a stronger sunburst dial in green. Enthusiasts call it close; pick based on whether movement features or build quality matters more to you.
