Citizen TSUYOSA Small Second Automatic 40 mm Textured Green Dial Stainless Steel Bracelet [NK5010-51X]

The Citizen TSUYOSA Small Second Automatic [NK5010-51X] represents one of the most refined and enthusiast-driven models within the TSUYOSA collection. Building upon the tremendous success of Citizen's integrated-bracelet sports watch platform, this elevated reference introduces a richly textured green dial, an elegant small seconds display, and the advanced Calibre 8322 automatic movement with an impressive 60-hour power reserve. The result is a watch that delivers significantly more sophistication and mechanical substance than its price point would suggest. 

While instantly recognizable as a TSUYOSA, the Small Second collection introduces several meaningful upgrades. Most notable is the beautifully textured dial, featuring a stamped pattern that resembles traditional guilloché finishing. The textured green surface creates remarkable depth and visual character, shifting between olive green, botanical green, and rich earthy tones as lighting conditions change throughout the day. At 6 o'clock, the recessed small seconds subdial provides additional visual balance while giving the watch a distinctly mechanical personality that sets it apart from conventional three-hand designs. 

The 40 mm stainless steel case retains the integrated-bracelet architecture that has made the TSUYOSA collection so popular worldwide. Its clean lines, balanced proportions, and signature recessed crown at 4 o'clock create a comfortable wearing experience while maintaining the sleek silhouette collectors have come to appreciate. The integrated bracelet flows seamlessly into the case, delivering the cohesive sports-luxury aesthetic typically associated with watches at substantially higher price points. 

Powering the watch is Citizen's impressive Calibre 8322 Automatic movement. This upgraded mechanical calibre delivers approximately 60 hours of power reserve, a significant improvement over the standard movement found in many traditional TSUYOSA models. Fully wound, the watch can be removed on Friday evening and still be running on Monday morning. The movement is visible through the exhibition caseback and features enhanced finishing that will appeal to enthusiasts who appreciate traditional mechanical watchmaking. 

Protecting the dial is an anti-reflective sapphire crystal that provides outstanding scratch resistance and exceptional clarity. With 50 metres of water resistance, the NK5010-51X is designed to transition effortlessly between business attire, casual wear, and weekend activities. The combination of refined styling, upgraded mechanics, and everyday practicality makes this one of the most compelling models in Citizen's current mechanical lineup. 

Among the TSUYOSA Small Second collection, the textured green dial stands out as one of the most distinctive and collector-oriented options available. It offers a level of dial detail, movement refinement, and visual sophistication that elevates the TSUYOSA platform into a category all its own.
