Tsuyosa NK5010-51X Automatic Watch
The Citizen Tsuyosa NK5010-51X is a men's casual watch powered by the automatic caliber 8322 with 21 jewels. It features a 40.00 mm stainless steel case, a textured green dial with index markers and a small seconds display, and a matching stainless steel bracelet secured by a deployment clasp. Mineral crystal protects the dial and the watch offers 50 m water resistance. This timepiece suits wearers who want a self-winding mechanical watch with an integrated bracelet for daily casual use.
Installation and Adjustment
The watch arrives ready to wear on the wrist; the deployment clasp opens and closes without tools for quick donning and removal. If the bracelet length requires alteration, links must be added or removed by a watchmaker or jeweller with the correct pin-pushing tools. The pull/push crown sets the time and winds the mainspring manually when the watch has stopped; overwinding is not possible with this automatic movement. Avoid adjusting the time while the crown is pulled out under water to maintain the 50 m seal.
Pre-Purchase Checks
Verify that a 40.00 mm case diameter and the stated case thickness suit your wrist proportions and sleeve clearance. Confirm that 50 m water resistance meets your needs; it covers splashes and brief immersion but not swimming or diving. Ensure you are comfortable with the green dial colour and index markers for legibility in your typical lighting. The automatic movement requires regular wrist motion or manual winding to maintain power reserve, so consider your wearing habits.

Questions about this item
How can I verify the automatic movement is running correctly after I put the watch on?
The caliber 8322 with 21 jewels drives the small-seconds hand; a steady sweep of that hand and consistent timekeeping over a full day confirm the movement is operating as intended.
What comes in the box and is anything else required to start using the watch?
The watch ships with its stainless steel bracelet and deployment clasp already fitted; no additional strap, tool or battery is needed because the automatic movement winds itself when worn.
Which version of the Tsuyosa should I choose if I want the green dial with a steel bracelet?
The NK5010-51X is the single model that pairs the textured green dial with a stainless steel case and bracelet in a 40.00 mm case.
