Rolex does not use simple stainless steel. It has its own proprietary process perfected in its own in-house foundry and this has proven to be truly resistant to scratches, dings, dimples and bumps. Again, I can be credible because I have been able to compare first hand....
Thought this was interesting -- have never heard any claim like that, you think they'd make a big deal about it. Oaga makes a good point, too, about the R&D they put in, and how their development has driven an awful lot of innovation in watches.
Whereas most watches use 316L Stainless Steel, Rolex uses grade 904L which is more corrosion resistant.
904L has greater amounts of chromium and nickel than the 316L grade. It is typically used in the chemical industry for severe corrosion environments i.e better resistance to pitting, SCC,IGC etc. I believe it is inherently anti-magnetic. The 904L alloy is a great deal more expensive than a 316L grade stainless steel.
Here is a good description of its qualities...
