I’m not so sure about that. Omega seem to be all over the place, sometimes the English way sometimes European.
Most (all?) catalogues from the other Swiss and German manufacturers that I have use the European system.
I prefer the English way as the spine text is still easily readable for books stacked cover up on a table, not so easy with the continental approach. I suppose there must be a good explanation somewhere for the logic behind the reversed spine text.
Interestingly, the International Wristwatch magazine started with the European way and the switched to English for the second edition and all subsequent ones.
Here’s a nice photo comparing & contrasting the spine text.
