Overview
The Citizen Series 8 NB6050-51W is a pinnacle of modern mechanical watchmaking within the 831 collection, blending a bold, industrial aesthetic with refined Japanese craftsmanship. It is characterized by its dynamic multi-piece case construction and a striking forest green dial. Designed for the contemporary professional, this timepiece prioritizes a "modern-sport" silhouette that is both rugged and thin. It features a high-performance automatic movement that emphasizes real-world utility, specifically engineered to thrive in environments saturated with modern electronics.
Technical Specifications
Case Size: 40mm (A versatile, contemporary diameter with a slim 10.1mm thickness)
Case Material: Silver-Tone Stainless Steel (Utilizing a complex multi-facet construction)
Movement: Caliber 9051 (Automatic mechanical; high-beat 28,800 vph with a 42-hour power reserve)
Crystal Type: Sapphire Crystal (Flat with anti-reflective coating)
Water Resistance: 100 Meters (10 ATM / 333 feet) — Robust enough for swimming and active daily use
Dial: Sunray-finished forest green with a subtle texture and applied baton indices
Bezel: Polished fixed stainless steel bezel
Strap: Integrated-style silver-tone stainless steel H-link bracelet
Special Features
Advanced Magnetic Resistance: The Caliber 9051 movement is built to meet JIS Class 2 magnetic resistance standards. It can maintain its accuracy even when placed as close as 1cm to devices emitting magnetic fields (up to 16,000 A/m), such as smartphones, tablets, and magnetic handbag latches.
Architectural Case Design: The case is composed of several distinct parts rather than a single mold. This allows for incredibly sharp transitions between hair-line brushed surfaces and mirror-polished edges, creating a high-end play of light.
High-Beat Smoothness: Operating at 28,800 vibrations per hour, the second hand moves in eight micro-steps per second, providing a smooth, fluid sweep across the dial.
Dynamic Green Aesthetic: The dial features a sunray finish that radiates from the center, causing the color to shift from a bright, metallic emerald in direct light to a deep, near-black evergreen in the shade.
Exhibition Case Back: A sapphire crystal window on the case back provides a clear view of the high-performance mechanical movement, including the decorated rotor and balance wheel.
Ergonomic "Integrated" Feel: While the lugs are standard, the bracelet is designed to flow seamlessly from the case lines, tapering toward the fold-over clasp to provide superior comfort and a balanced weight distribution.
Refined Legibility: The hands and indices are diamond-cut to catch the smallest amounts of light, supplemented by luminous inserts on the hour and minute hands for visibility in the dark
