I didn’t realize Rolex has been using 904 since 1985 in the Seadweller ... interesting.
Thanks for the post |

I’m going to call partial BS on this. I’m going to call 904L as a USP marketing thing.
If corrosion occurs primarily on the watch back through contact with salty perspiration, then a) a lot more non-Rolex’s would have this problem and b) so would other areas of the bracelet and case. My guess is that it is the finish of the watch back that is causing a metallurgical problem I.e corrosion as the relatively rough finish provides ample opportunity for a metal-water-oxygen boundary to form. Add NaCl and corrosion will accelerate. However, if the case back was more highly polished, I doubt you would see that problem on any stainless steel 904 or otherwise. My 20year old Breitling Chronomat (daily beater) which has seen daily exposure to hot, humid, mildly corrosive environment shows no signs of pitting. The problem is a Rolex thing not a Stainless steal grade thing |

All the information of the different grades of steel is on the internet. And yet there is plenty of non factual claims on the internet for the "super-alloy" 904L. Contrary to many posts on this and other forums, it is not harder tgan 316L, and is in some areas it scratces easier.
Technically is is more corrosion resistant, but as others have said, this is not particularly relavent to the average user. I imagine that is a different story for deep professional divers, where the pressure will accelerate the reactions. But that isn't worth anything to us except bragging rights, so, not worth anything. The one area I can believe is that 904L polishes differently. So our Rolex look a bit more bling than other non-PM watches. So as always Rolex know best: they know we are attracted towards shiney. |

i prefer the luster of 904. but constructively other than another differentiator i dont think it makes much difference.

This thread is funny. Love to see the Rolex haters come out with all their data.
....bad marketing, 904L is the same as toilet paper, Fossil uses 316L and has no problem...lolsss |

It’s not just marketing. Sure, you can claim that most Rolex watches are now luxury pieces and not used as tool watches, but from a technical perspective modern Rolex are better tool watches than they’ve ever been. Solid clasps and bracelets, higher depth ratings, wear-resistance ceramic... they are definitely better tool watches than ever and 904L’s corrosion resistance is a part of that.

Machineability. 316 does not respond to high speed working.

At least for period anyway. There are things we mere mortals will never entirely know about the matter, and Rolex will never ever tell. |

I don’t disagree with anything you say. But we’ve all seen the photos of case backs with pitting so it clearly does happen. I just don’t understand the logic of “Since nobody abuses their watches anymore we shouldn’t bother improving them.” |

Agree but all the case back pitting photos are mostly from way back in the 1980s and was mainly down to the watches never been serviced.Fact no matter the SS if serviced at the correct time say every 5-8 years if used in salt water 5 years.There would be no pitting whether 316L, 904L,or even if they call it oystersteel brands like Patek still use 316L as most of the whole watch industry.

So I maintain that Rolex really believes it's a functional improvement. |

I would like to point out that the likelihood of a Patek being subjected to the same levels of usage or for that matter, level of neglect or abuse is in order of magnitude absolutely fractional. To that, no direct comparisons can possibly be drawn without a controlled study. Likewise with regard to comparisons with other brands using 316 SS and Rolex watches. It's anecdotal at best. Ther are still two, three or even four distinct variables not yet ever discussed on the matter in the domain of this forum, that also feed directly into the equation. I totally agree that regular servicing is important. However, there is nothing special occuring with a Rolex service that doesn't also happen with other brands which can be directly attributable to mitigating the effects of corrosion. |

And impossible to refute. In SS they are still tool watches, but the level of finishing and material specs utilized throughout the watch put them right at the top of their category |

Rolex is known for evolving their watches and making them better. Ceramic and 904 steel cannot be argued they are improvements on paper. However, considering the fact there are many perfectly useful Rolex's from the 50's and 60's and even older still in use improvements are relative at best.
