Authentic and original Russian watch! Mechanical movement – hand wound. This is a vintage Russian watch with a diameter of 35 mm and a mechanical movement, which is hand-wound. The pictures are considered part of the description. The case nickel plated with bare areas as shown in the picture. The acrylic is in pretty good shape. This watch is running and functions properly, although it has not been checked for timekeeping. Unknown service history and, as any vintage watch, water resistance is not determined. Please review pictures for more details on condition and feel free to ask for additional angles or any questions you may have. Keep in mind that these are vintage watches that have not been tested and I can only provide the information I can verify such as proper winding and running condition, but it may need servicing. Thank you for looking and please ask any questions.
