Model Reference: NB6060-58X
Overview
The Citizen Series 8 NB6060-58X is a standout member of the 890 series, representing the sportiest and most robust evolution of the Series 8 mechanical lineup. It is defined by its vibrant emerald green dial and a distinctive octagonal three-part case design. This model is an "all-terrain" luxury watch, bridging the gap between an integrated-bracelet sports watch and a professional diver. It features a unique dual-crown configuration to manage an internal timing bezel, offering a clean, architectural silhouette that conceals high-performance diving capabilities and advanced magnetic resistance.
Technical Specifications
Case Size: 42.6mm (A bold, faceted presence with a height of 11.7mm)
Case Material: Silver-Tone Stainless Steel (Finished with a mix of brushed and mirror polishing)
Movement: Caliber 9051 (In-house Automatic; high-beat 28,800 vph with a 42-hour power reserve)
Crystal Type: Sapphire Crystal (Anti-reflective coating for a crystal-clear view of the dial)
Water Resistance: 200 Meters (20 ATM / 660 feet) — Professional-grade resistance suitable for all water activities
Dial: Emerald green with a geometric "skyscraper" texture and applied indices
Bezel: Internal bi-directional rotating bezel (Controlled by the secondary crown at 2 o’clock)
Strap: Integrated-style stainless steel H-link bracelet with a hidden deployment clasp
Special Features
Geometric "Skyscraper" Dial: The dial features an intricate, repeating pattern inspired by the windows and shadows of a modern skyline. The emerald green color is dynamic, shifting from a bright, metallic luster in direct sun to a deep forest green in low light.
Internal Timing Bezel: This model utilizes an internal rotating ring instead of an external one. This allows the watch to retain its sharp, octagonal luxury profile while still providing a 60-minute scale for tracking elapsed time.
JIS Class 2 Magnetic Resistance: The Caliber 9051 movement is heavily reinforced against the magnetic fields of modern life (up to 16,000 A/m). This ensures that placing the watch near a smartphone, laptop, or magnetic clasp will not disrupt its mechanical precision.
5-Piece Case Architecture: The case is assembled from five distinct sections. This modularity allows for "Zaratsu-level" finishing where sharp angles meet brushed planes with surgical precision, a hallmark of Citizen’s premium Series 8 line.
High-Beat Performance: Operating at 8 ticks per second ($4\text{ Hz}$), the movement offers a smooth, fluid sweep of the second hand and superior stability against shocks compared to lower-frequency mechanical watches.
Exhibition Case Back: Despite its 200m water resistance, the watch features a sapphire display window on the back, allowing a full view of the industrial-finished automatic movement and its rotor.
Dual Crown Ergonomics: The 3 o'clock crown handles time and date setting, while the 2 o'clock crown is dedicated to the inner bezel. Both are engineered with a tactile, cross-hatched grip for ease of use.
Professional Lume: The indices and hands are generously filled with luminous material that provides a strong contrast against the green dial, ensuring the watch remains functional in total darkness.
