Written in the circle at the bottom and top is the info that the gasket belongs in the caseback (in 4 languages: English, German, Spanish, French). The numbers are the references - the caseback is used for both references 2759 and 2761, two Omega models that used the same case. The “12” is the sub-reference, possibly indicating a dial Lay-out (or a few) and meaning it’s a later model of that reference. “SC” means seconde central - it’s a center second, as opposed to a subdial second. Acier indoxyable means stainless steel. Omega doesn’t need translating, Fab Suisse is the same as Swiss Made, for the patent I’m not entirely sure if that’s the patent for the case, the entire watch, …
Bottom line: Have you tried googling that? I guess it all translates pretty easily.
😉
Enjoy your watch!
