This is a Certina Argonaut 280 automatic for parts or refurbishing. It was given to me when I was about 10 ( circa 1977) from my uncle who owned a jewelry store. I am pretty sure I overwound it immediately after I got it and it hasn’t run properly since. The second hand will start to move, for awhile and then stops. The video shows the second hand moving along . The band is marked 1/20 10kt GF Kreisler USA The face is about an inch in diameter and most likely stainless steel. There is a small crack at 5 o clock. Please see all the photos and video for a full description.
