Citizen Tsuyosa Yellow Dial Automatic Watch

The Citizen Tsuyosa NJ0150-81Z is a men's dress watch with a 40.00 mm stainless steel case and matching bracelet. It runs on the automatic Caliber 8210 movement with 21 jewels and displays the time on a yellow dial with index markers. A date window and sapphire crystal complete the analog display.

Upgrade from quartz or entry-level automatics

This model replaces battery-powered quartz watches or basic mechanical pieces with a self-winding movement that charges through wrist motion. The sapphire crystal offers superior scratch resistance compared to mineral glass found on lower-tier watches. The jump is worth it for buyers who want a durable, tool-free bracelet adjustment via the deployment clasp.

Practical limits of 50 m water resistance

The 50 m rating suits daily hand-washing, rain and light splashes but is not rated for swimming, diving or high-pressure water jets. The fixed bezel provides no elapsed-time tracking for underwater use. Owners should avoid operating the crown or pushers while wet to maintain the seal integrity.

Questions about this item

What case diameter does the 40.00 mm Citizen Tsuyosa NJ0150-81Z require for a strap change?

The watch has a 40.00 mm stainless steel case with integrated lugs; measure the lug width directly before ordering a replacement strap.

How do I set the date on the 8210 automatic movement without damaging the mechanism?

Pull the crown to the first position and turn clockwise; avoid changing the date between 9 pm and 3 am when the date gear is engaged.

When will the sapphire crystal or 21‑jewel movement need professional service?

Expect a full movement clean, lubrication and seal check every three to five years; the sapphire crystal only needs replacement if scratched or cracked.
