Management Number 0615 0609 E 529 #28 This is a popular diver-style model equipped with SEIKO's proprietary Kinetic movement. By generating electricity through the movement of the wrist and storing it as power, the watch combines the high precision of quartz with the practicality of a mechanical watch. This is a genuine scuba series designed with 200m water resistance, featuring a unidirectional rotating bezel and day-date display. The blue dial and highly legible indices create a sporty impression, making it suitable for both formal and casual occasions. The case size is approximately 42mm (excluding crown), giving it a strong presence on the wrist. The watch is currently running. The case and band show scuffs and minor scratches from use.
