The Citizen Tsuyosa Small Second NK5010-01H stands out as the leather-strap variant in the Tsuyosa Small Second lineup. Sharing the same core architecture — a 40 mm stainless steel case and recessed 4 o’clock crown — this model pairs a textured gray dial with a classic black leather strap for a slightly dressier, more refined character while maintaining a sporty backbone.

At its heart is the automatic Citizen Caliber 8322, featuring a 60-hour power reserve and dependable mechanical operation without batteries. The textured dial includes a small seconds sub-dial at 6 o’clock, enhancing both legibility and aesthetic balance. A sapphire crystal covers the dial, offering excellent scratch resistance.

With 50 m / 5 bar water resistance, the watch is suitable for daily wear, surface splashes, and casual activity without compromising performance. The leather strap with a buckle closure adds comfort and style, making this reference a versatile choice between casual daily wear and smarter occasions.
