Thank you for the info Noddyman, I spent a chunk of Sunday researching and reading about Constellation dials. The lack of the 'Officially Certified' almost put me off until I saw the Reference pic and I quite like the two line simplicity. I have seen other examples but can't recall if they were in the earlier case shapes.
I think I'll call the dealer and have a chat and see if there's more pics of the the case and if he's got any more history.
