I have an Omega 715 Constellation that needs a case. I have been unable to find one and expect rare to unavailable. Many gold cases wasted. Thus, a Seamaster or other option is a consideration. Better a Frankenwatch than no watch. I'm not sure of potential fit per Internet sales.

 

Is it a moonface watch case you are looking for ? Check the net for cal omega 715 to see what reference the watch has . It would make it easier to search for a case .
