Omega Constellation Chronometer automatic winding WG bezel. The bracelet is genuine Omega, and the crown is also an Omega crown. Please check the photos. The reason for the scratches and dirt is that, as shown in the photos, there is some dirt on the dial, and there are visible scratches on the back cover. I used it normally, so there are many small scratches on the case and belt when viewed with a loupe. What constitutes a noticeable scratch is subjective, but please understand that it is not without scratches. Thank you. Manufacturer: Omega Movement: Automatic winding Year: 1970s Case size: Approximately 36mm, bezel is solid WG Condition: Running. Although the power reserve is not clear due to the automatic winding, it gains or loses about a minute even after wearing it for a day. It was overhauled at a local watch shop in September 2023, so it can still be used as is. There are no certificates, etc. Thank you for viewing. Please feel free to ask any questions. Thank you. #Omega #OmegaConstellation #AutomaticWinding #Wristwatch #AutomaticWindingWristwatch Dial color: Silver Belt color: Silver Omega Collection: Constellation Omega Case/Color: Stainless steel Omega Case/Diameter: 36mm Omega Strap/Material: Stainless steel Accessories: None Operation: Good
