Hello everyone, I am new to the forums but not new to the world of Omega. I am considering purchasing either an Omega Seamaster De Ville or a Seamaster Cosmic. If I buy the Seamaster Cosmic I would like to buy an original crown for it since it currently has an aftermarket crown on it. It is a non day and date and features the 14kt gold filled case thus I will need a 14kt gold filled Omega crown that is original to the Omega Seamaster Cosmic. It is a 135017.
