This is a classic vintage quartz wristwatch made by CITIZEN. It features a slim and elegant rectangular case paired with a stainless steel metal bracelet, creating a clean design. The dial emphasizes only the "12" and uses elongated indexes to evoke a retro atmosphere. The movement is a 5421, and the case back is stamped with authentic markings including "5421-S021243 HST / 951022". Both the buckle and the case back are engraved with the CITIZEN logo, and the watch is generally in good condition. It is suitable for everyday use and is recommended for those looking for a classic Japanese-made watch or for collectors. There are some minor scratches and scuffs on the metal parts due to use, but please understand this is a vintage item. Overall face size (including the connection to the belt) is 3.5cm, width is 1.6cm, and the belt width is 1cm.
