The only detail I question is the reference number that the auction house believes it corresponds with. It's listed as a "Ref. 2413" as a result of a faint inscription on its caseback. Omega collectors will know that the Ref. 2413 is in https://www.ctrwx.co.uk fact a time-only watch powered by the ultra-thin Cal. https://www.brwx.co.uk/Collection/professional/ 360. My guess is this https://www.ctrwx.co.uk number on the caseback is for internal records purposes in reference to the project.
