Watch Description
Watch Description
The Citizen Series 8 NB6050-51W (popularly known within the watch community by its series nicknames, the "Series 8", "Series 8 831", or "831 Mechanical") is a high-performance, sports-luxury Swiss-inspired automatic dress watch. Relaunched as part of Citizen's flagship Series 8 line, this 40mm timepiece combines clean geometric architectural lines with high-grade mechanical finishing. Built for modern executives and watch collectors who value understated luxury and anti-magnetic engineering, it transitions seamlessly from formal business environments to casual weekend wear. The defining visual highlight of this NB6050 reference is its rich, textured green dial inspired by contemporary urban architecture. The patterned surface catches and reflects light dynamically beneath razor-sharp faceted hour markers and luminescent hands filled with high-visibility white paint. A clean date window sits at the 3 o'clock position, framed by a multi-faceted bezel and a brushed stainless steel case. Beneath its sophisticated exterior, the watch is powered by Citizen's in-house Caliber 9051 automatic mechanical movement. Operating at a frequency of 28,800 vibrations per hour with 24 jewels, this automatic engine delivers smooth sweeping central seconds, manual hand-winding capability, and second-hand hacking for exact time setting. Engineered for modern life surrounded by electronics, the Caliber 9051 features advanced magnetic resistance up to 16,000 A/m, ensuring rate stability near smartphones and everyday magnetic fields. Driven by the motion of the wearer's wrist, it provides a power reserve of up to 42 hours. The 40mm watch case is meticulously crafted from solid 316L stainless steel, featuring a slim profile of just 10mm for effortless under-cuff wear. Dial protection is provided by a scratch-resistant synthetic sapphire crystal treated with anti-reflective coating for glare-free optical clarity. The case features a screw-down solid caseback and achieves a certified 100-meter (10 bar / 330 ft) water resistance rating, making it fully capable of handling swimming and daily aquatic activities. The timepiece comes completed on an integrated stainless steel H-link bracelet with alternating brushed and mirror-polished facets, fitted with a fold-over deployment clasp and double push-button release.
