What year 904L?

Greetings R-L-X!

Does anyone know what year Rolex began using 904L grade stainless steel in their watches, and what grade was used previous to 904L? :grb:

I think the current standard of knowledge says: 316L until 1988 with the introduction of Ref. 168000

Thanks much guys...I see there isn't complete agreement from our respondants on this topic. :grb:

I'm not familiar with 1916L...does it rate somewhere between 316L and 904L?
