This is a Seiko 5 khaki military watch. It is currently running without any problems, and setting the time, date, and day of the week is also not an issue. Although I haven't measured the exact daily rate, I didn't notice any abnormalities. The original strap shows some signs of wear, and the watch body may have some scratches if you look closely, but I think it's in very good condition.
