Seiko manual-winding watch, EXTRA FLAT. It moves slightly when wound, but stops quickly within a few seconds, so please consider it non-functional. Looking at the movement, the area around the balance staff is dirty, and it appears that the oil has solidified. Also, the keyless works screw seems to be broken, and the movement is loose. The dial is also dirty, and the overall condition is not good, so I am selling it as junk. For those who can repair it, how about it? Please note that this is a sale of the watch body only (without a band).
