·It’s commonly known that most modern stainless steel watches (Omega included) are commonly using 316L steel which is harder, but less corrosion-resistant that Rolex’s 904L steel.
I’m curious if anyone knows what type of steel was used on the vintage Omega models such as the original 1957 Trilogy models.
Anyone?
