All my communication with Omega has been through webform and the email response is from an unmonitored email address. The response was from the UK though.

I think they changed their policy over the years. Used to be easy to get the COSC certificate...they'd happily send it out by post if you provided the watch details. Same with things like catalogues...they used to be happy to post out catalogues on request...nowadays they wont...must eat into that profit margin.
