This is a Casio Sports Gear watch. It's a sports watch with 20-bar water resistance, so you can use it with confidence for marine sports, swimming, and more. The size of the dial is shown in the latter half of the images, so please refer to them. Since I have many items for sale, please refer to the images for any scratches or stains. Before listing, I have replaced the battery, disinfected it with alcohol, and confirmed its operation, but I do not guarantee its continued operation in the future. Please understand. This is a one-of-a-kind used item, so I do not recommend it to those who are looking for the quality of a current new watch. If you have any questions, please feel free to ask! Instant purchase is welcome! Items that have not been purchased for a long time may be removed from the listing without notice, please forgive me. Followers will receive a flat 3% discount on their first purchase. Repeat customers will receive a flat 5% discount from their second purchase onwards. Please let me know in the comments before purchasing, and I will make the changes. I cannot accommodate follow-up notifications after purchase, so please be sure to contact me before purchasing. I am mainly selling watches, and I am selling various items to organize my collection. I would be happy if you would take a look at my other items as well. ↓↓↓↓↓ #PopotaWatchMens
