Citizen Tsuyosa Green Dial Automatic Watch

The Citizen Tsuyosa NJ0150-81X is a 40 mm stainless steel dress watch powered by the automatic calibre 8210 with 21 jewels. A green sunburst dial with index markers sits beneath a domed sapphire crystal. The integrated stainless steel bracelet secures with a deployment clasp and the case offers 50 m water resistance.

Suited for daily wear and dress occasions.

This timepiece suits professionals and enthusiasts seeking a versatile mechanical watch with a distinctive green dial for office or evening wear. The 50 m rating covers splashes and brief immersion only, so buyers who need a watch for swimming, snorkelling or diving should look at a model with a higher water-resistance specification.

Calibre 8210 automatic movement with 21 jewels

The calibre 8210 drives hours, minutes, seconds and a date window at three o’clock without a battery. Its 21 jewels reduce friction for reliable daily running. If your purchase decision depends on a specific movement architecture, this calibre is the single specification to verify.

Questions about this item

Does the 8210 automatic caliber require a watch winder if I don't wear it daily?

No, the 8210 movement runs on wrist motion alone. A winder is optional; manual winding via the crown also keeps it going.

Will the 40.00 mm case and 50 m water rating suit daily desk work and hand-washing?

Yes, the 40 mm stainless case fits most wrists and 50 m resistance handles splashes, rain and brief immersion.

How can I confirm the sapphire crystal and 21-jewel movement are genuine after unboxing?

The crystal should show no rainbow glare at an angle, the case back lists caliber 8210 with 21 jewels, and the seconds hand sweeps smoothly.
