Thank you for viewing. This is an Actus, a turtle-type watch. It is functioning within a practical range. Pressing the crown firmly changes the date and day of the week. Pressing it lightly changes only the date. The band is an aftermarket product, and fits a wrist size of approximately 16cm. There are no extra links. There are minor scratches on the body. They can be removed with polishing. There is also some dirt. #Seiko #Automatic #Vintage #Fashion #Coordination Dial color: Silver
