Thank you for viewing. ■ Seiko quartz wristwatch with a square design, 2620-5570. ■ It is currently running after I put in a test battery. 【Condition】 ■ The glass surface has no noticeable scratches. There are many frame plating剥げ (peeling), scratches, and scuffs, making it a used item with a sense of use. ■ Band inner diameter: Approximately 5cm ■ Band design: Link-style metal ■ Dial color: White ■ Dial style: Roman numerals ■ Case shape: Square 【Shipping Details】 ■ Yu-packet Post (anonymous shipping, delivered to mailbox) ■ Simple packaging to prevent damage to the product 【Notes】 ■ The current test battery may have a short lifespan. The correct battery is "SR726SW". The back cover is the type that can be easily opened by amateurs with a flathead screwdriver, so I suggest you replace it yourself. ■ The photos tend to look cleaner than the actual item. Please understand that this is a used item in poor visual condition before purchasing. ■ I do not have expert knowledge about the product, so I cannot answer specialized questions. Please refer to the images and make your own judgment.
