Up for sale is the pictured Omega Speedmaster "DON" dot over 90 bezel for vintage models ranging from the 2998 through the 145.022-69, including the 105.002, 105.003, 105.012, 145.012, and 145.022.
This bezel is in used but still very good condition and shows some surface wear throughout which has been detailed in the numerous close-up photos of the entire bezel shown in the listing. The bezel is also flat as shown with no warping and should fit on your vintage Speedmaster without any issues.
The bezel is free from any large dents but does show a small nick right around the 76 marker visible in the photos. There is a small portion of lighter colored fading ranging from the 200-110 area, and numerous surface markings commensurate with a 60 year old watch component.
This bezel is 100% original and comes from a personal stash of vintage watch parts. It is shown laid on but not mounted to a Speedmaster Provisional to provide a preview of how it may look on your watch. Obviously, the watch is not included.
Please note that all of these photos were taken in a light box with the harshest possible lighting to highlight each individual imperfection. The bezel is much more handsome "in the flesh" than in these photos. The final photo of the bezel on a watch in my hand was taken in more natural light.
The bezel will be securely packed and ships FREE within the United States. I'm happy to answer any questions. Thank you for looking!
