Citizen NK5010-51X Tsuyosa Automatic Small Second 40mm Green Men's Watch

The Citizen NK5010-51X: mechanical automatic and sapphire crystal

Overview

With the NK5010-51X, the Tsuyosa range welcomes an automatic men's watch, powered by wrist movements. The Tsuyosa collection is dedicated to Citizen's automatic watches. On the green dial, the time is indicated by hour markers. The case and bracelet are made of stainless steel, and the diameter reaches 40 mm. This purchase comes with a 2-year warranty.

Case

Made of stainless steel, the case sits on the wrist with a 40 mm diameter and 11.7 mm thickness. The dial is protected by a sapphire crystal, and it is surrounded by a fixed bezel; the movement is hidden behind a transparent case back. The stated water resistance is 50 m (5 ATM): the watch supports bathing and swimming, but not diving.

Movement

With the 8322-C0A caliber, Citizen offers a mechanical automatic movement: the rotor turns with the arm and recharges the spring. In use, it stops the second hand during time setting thanks to the hacking feature. Placed on a table, it maintains 60 hours of power reserve.

Bracelet

The watch is worn on a silver-tone stainless steel bracelet, with a 13 mm lug width. The whole weighs 147 g.

Supplied with: Storage box, presentation pad, user manual.
