From my collection. A Citizen vintage quartz watch. Sporty Air Diver. It has a nostalgic design, probably from the early 1990s. The glass, case, and belt are all in good condition with no noticeable scratches. The bezel rotates smoothly. The crown is a screw-down type and functions without any problems, including crown operation. It is running without any issues after replacing the battery with a new one. Case width is approximately 36.5mm (excluding the crown), and the wrist size is about 17.5cm. The buckle also closes properly. I will wrap it in bubble wrap and ship it via Mercari's Nekopos service, which will be delivered to your mailbox. Thank you.
