Case size: 39mm (excluding crown) Vintage hand-wound wristwatch made in the former Soviet Union, Russia. *As you may know, the Vostok crown operation is unique: loosen the crown to wind the mainspring. Pull out one step to set the time. Of course, winding the crown and setting the time are not a problem. The strap has been changed to rubber, not the original. Rare non-date men's size. It has been thoroughly wiped and is in a clean condition, but the dial has a long-term aged appearance. Please check the images before purchasing. We will pack and ship it safely.
