Thank you for your interest. Please review the following information. [Product Information] This is an automatic winding wristwatch from SHIPS. It's a type that automatically winds the mainspring with the movement of your arm, so you don't need to wind it manually as long as you're wearing it. The operation has been confirmed, and if it stops, it will start again if you shake it. Currently, it's the perfect size for someone with a wrist size of 16cm, but the removed band parts are also available, so adjustment should be possible. I cleaned it a while ago, so I don't think there are any noticeable stains, but please be aware of minor scratches etc. that come with use. There is dust in the box, but it's difficult to remove, so it's left as is. Please consider it as a bonus. I have other items for sale, so please take a look if you'd like. We look forward to your purchase.
