Management Number 0520 0515E3121 394 165 A timepiece crafted by CITIZEN, featuring a genuine automatic (self-winding) movement. It is equipped with the Caliber 4166, also adopted in high-end mechanical models from CITIZEN, offering reliable precision and the bold presence characteristic of mechanical watches. This is a working piece, currently keeping accurate time. The sub-dials on the dial — including a 24-hour indicator — create a sporty yet intellectual mechanical feel, elevating the appearance at the cuff in business settings. The visible rotor movement through the caseback adds to the pleasure of owning a mechanical watch. A dependable timepiece that combines functional beauty and durability for long-term use.
