CITIZEN INDEPENDENT CHRONOGRAPH Watch Battery replaced, operation confirmed. The chronograph also works perfectly. The octagonal body, the date display at the 12 o'clock position, the chronograph layout, and the index design are all cool. The crystal is made of a blue mirror-like material, and the appearance changes depending on the angle. The chronograph on the right is a 1/10 second counter, and the long hand ticks at high precision, about four times per second. There are signs of use, scuffs, and scratches. The wrist size is about 17.8cm.
