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...

Now thats a tidbit I did not know. I guess I should do a little more research on some of my watches. That does explain why my stainless Rolex just always looks a little brighter and shinier than my other Stainless watches. Although, they still scratch about the same. Almost two years after its last polish by Rolex and its ready for another.

I don't know if my next watch purchase will be another Rolex. There is one I want but funds are short on that and I can score a couple other less expensive watches I've been wanting anyway. The Debaufre Airforce Orange is calling my name loudly :dude:
