Compact automatic timepiece for daily wear

The Citizen Tsuyosa NK5010-51L is a 40 mm stainless-steel watch powered by the automatic calibre 8322. Its blue dial with index markers and small-second sub-dial suits professionals and enthusiasts who want a single, versatile piece for office and weekend use.

Stainless construction with sapphire protection

A solid stainless-steel case and matching bracelet resist everyday knocks, while the sapphire crystal guards the dial against scratches. The fixed bezel and 50 m water resistance handle hand-washing and rain, and the deployment clasp secures the bracelet with one-handed operation.

Integrated bracelet and hacking movement

The supplied steel bracelet eliminates the need for aftermarket straps, and the calibre 8322 stops the seconds hand when the crown is pulled for precise time setting. No additional tools or software are included, so the watch is ready to wear straight from the box.

Questions about this item

What does the 50 m water-resistant rating actually cover in daily use?

It protects against splashes, rain and brief immersion such as hand-washing, but is not rated for swimming or showering.

How much wrist space does the 40.00 mm case thickness and stainless-steel bracelet require?

The 40.00 mm case sits on a solid stainless-steel bracelet with a deployment clasp, so the watch needs a flat surface at least that wide to sit flush.

How do I start the Caliber 8322 automatic movement after the watch has stopped?

Unscrew the crown, wind it clockwise until you feel resistance, then screw the crown back down fully — the step most people miss is re-securing the crown to keep the 50 m seal intact.
