A noticable diffrerance on two out of the package watches. As the two watches age, are beat up, received differant levels of maintance, the differance becomes minimal. I know a guy with a 3 year old rolex that is so dirty he has to spit on the crystal to read the time cause it gets so many fingerprints, sweat, grease, ect on a daily basis and is rarely cleaned. My watches get a cleaning each night before going to bed when i wear them, and another before i put it on. My watches are typically more brilliant then the average watch owners regardless of brand.Dizzy said:doesnt the 904 have more nickle in it thus making it a slightly different color? I know one of the two is more blueish looking and one is more greyish looking. You would never be able to tell unless you had the two side by side, then theres definatly is a noticable difference.

Rolex uses 904L also 316L but the myth of the "special Rolex steel" comes up frequently. An employee of Rolex said in 2002: Quote.
At the moment, we have several companies all over the world, serving our needs for stainless steel. The watch cases and bracelets are all mainly made of X2CrNiMo17-12-2 which is the best compromise between the attributes of the variant materials. As usual, the steel is melted under vacuum, so we get an very pure base, which is easy to handle and allows an perfect polishing. I think, the same procedure as in every good (expensive gold) company,and now X2CrNiMo17-12-2 is used for parts than come into skin contact
One of those providers is http://www.boehler-thyssen.ch/
Rolex does use indeed Steel 904L, but only for parts that are not in direct contact to the skin. 904 has a higher amount of Nickel than 316, so it is used for parts such as case ring bars screws pins etc.
X2CrNiMo17-12-2 is the formula for 316L SS.
Now perhaps this has changed,but I would doubt.Don't think Rolex would put anything on sale that could possible
cause a allergy without some sort of warning on label.
904L is a non-stabilised low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid. It is also highly resistant to chloride attack - both pitting / crevice corrosion and stress corrosion cracking.
This grade is non-magnetic in all conditions and has excellent weldability and formability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.
904L does have very substantial contents of the high cost ingredients nickel and molybdenum. Many of the applications in which this grade has previously performed well can now be fulfilled at lower cost by duplex stainless steel 2205 (S31803 or S32205), so it is used less commonly than in the past.
It is not easy to trplicate a process, Doc. Have some respect :wink:AllergyDoc said:
