This is a hand-wound (one-day wind) watch from the Showa era. I have confirmed that it works and the bell rings after winding the mainspring. I have not checked it for 24 hours, so I don't know if it is slow or not. As you can see in the photos, there is some slight distortion. There is also rust and dirt. Please consider this item with the understanding that it is old and has been stored at home for a long time. Please refrain from purchasing if you are sensitive to such things.
