Vintage Acuet Japan Eagle Engraved Pocket Watch

Vintage Acuet Japan antique looking silver toned pocket watch with a eagle engraved on the front. Comes with chain but missing end attachment piece. I just put a new battery in it and is working well. See video. There is some wear on metal showing it’s age. See photos. Measurements are in the photo section. Feel free to contact me with any questions. Thank you.
