It does have the omega etching in the centre of the crystal. I use them for converting my DD's to a domed non cyclops look They are a perfect 5Bar waterproof fit: the reason I ask is because others have asked me where they can get them for the same conversion and I too am having trouble finding them.
I know that OMG 306 296 is the correct number but I cannot tell if that packaging is original as it's not my picture I originally attached at the start of this thread. I think that 306/296 refers to the internal and external widths. My understanding is that it was maybe used for one of the Seamaster models.
I've attached a picture so that you can take a look at the centre etching thanks.
