I don't know anything about it other than it probably came in a bag of junk watches I bought by the pound on eBay. Inside it says no jewels, unadjusted, Miyoto Co., Japan.
Photographs oddly here, but it's got a highly polished chrome case. Very dressy watch. It's unisex, so it would make a nice, dressy, large woman's watch, or a dressy man's watch if you've got small hands.
