Citizen Automatic Watch Mechanical, Self-winding with manual winding I am not sure about the details of the movement. It has been repaired, and a Citizen dial has been installed on a watch with a missing manufacturer's name (it is a Citizen watch). The dial is not clean. It seems to have enough accuracy for daily use when worn on the wrist. Please understand that it does not have the accuracy of recent high-performance watches as it is old. The calendar is broken. An aftermarket band is attached. Cut sheet attached (Please refer to the photos) As a bonus. Lug width 18mm Wrist size approximately 175mm, no extra links. Citizen mechanical watch For those who enjoy the taste of mechanics, please take care of it.
