Thank you for viewing. Please be sure to read the self-introduction and product description to the end to prevent trouble, as there are people who purchase without reading the product description and give bad reviews! I think this was probably owned by my grandfather. I don't know anything about watches, but I have only confirmed that it works by shaking it. I would appreciate it if you could judge the appearance from the photos. We are waiting for purchases from those who understand that this is a used item and a personal sale.
