Model Reference: NK5010-51X
Overview
The Citizen Tsuyosa Small Seconds NK5010-51X is an evocative mechanical watch that blends vintage horological complications with a bold, retro-modern integrated design. This model is defined by its striking sunray forest green dial, which features a complex diamond-patterned guilloché texture. A departure from the traditional three-hand layout, this timepiece utilizes a small seconds sub-dial at the 6 o'clock position, lending it an air of classic sophistication. Encased in a brushed and polished 40mm stainless steel frame, it captures the "sport-chic" essence of the 1970s while housing a high-performance, modern automatic caliber.
Technical Specifications
Case Size: 40mm (Ergonomic, integrated sports profile)
Case Material: Silver-Tone Stainless Steel
Movement: Caliber 8322 Mechanical (Automatic, self-winding movement with a 60-hour power reserve and hacking/stop-seconds functionality)
Crystal Type: Sapphire Crystal (Premium scratch resistance for superior durability and clarity)
Water Resistance: 50 Meters (5 ATM / 165 feet) — Designed for daily use, rain, and splashes
Dial: Textured forest green dial with silver-tone baton indices and a dedicated seconds sub-dial at 6 o'clock
Bezel: Fixed, polished silver-tone stainless steel
Strap: Integrated silver-tone stainless steel bracelet with rounded "President-style" links and a deployment clasp
Special Features
Small Seconds Complication: By moving the seconds hand to its own sub-dial, the watch achieves a more traditional and
technically detailed aesthetic, distinguishing it from standard center-seconds models.
Extended 60-Hour Power Reserve: The Caliber 8322 provides a substantial 2.5 days of running time when fully wound, allowing the watch to maintain accuracy even if not worn over a full weekend.
Guilloché Dial Texture: The intricate geometric pattern on the green dial surface creates a dynamic visual effect, catching and diffusing light differently from every angle.
Exhibition Case Back: A transparent window on the reverse side offers a view of the 21-jewel mechanical movement and its decorated oscillating rotor.
Seamless Integrated Design: The lugs are designed to flow directly into the bracelet, creating a unified, sculptural look that ensures the 40mm case sits comfortably and securely on the wrist.
Luminous Markers: Features luminous-filled hands and indices for enhanced legibility during nighttime or in low-light conditions.
