Does the current Rolex watches ever rust?

[funkycatspangky]

I read the Sinn thread where one bro reported of his rusting Sinn watch with concern.

Does the current batch of rolex watches ever rust?

[AK28]

yes... sinn watches do rust (at the buckle)

The buckle and third party parts do rust... according to AD. This is because they are not made of the same type of Steel. bummer but the rust does not seem to be too serious. therefore, it can be brushed off quite easily. ALso, when aired properly after a swim, the rust seldom comes back. (IMO)

Nahhh...the steel is 316L or 904L....above average standard...damn solid

[crazyfingers]

I thought Rolex used 904L for all its current watches

[Darkangel]

904L is current...I included 316L which is the older batch too...

[crazyfingers]

904L is current...I included 316L which is the older batch too...

Ah ! And correct me if I am wrong, but Tudor still uses 316L steel right?

That is a thought guys, anyone know what steel currently being used for the Panerai?

316l and 904l does not rust?

ever?

316l & 904l

Halo Friends,
Acc to the ASTM/ASME Standard, different grades of stainless steel is differ by the Amount of Nickel & Chromuim content in the grades itself.

In the case of current Rolex cases, 904L, it's really not possible to see rust.
The problem is when we hear about rusty inner case, we start to wonder why?
Answer: when eg. Sea Water seeps into the case, if not properly serviced, interacts with the rest of the movement parts causing rust to form. Thereafter a "corroded inner case".

Hops this helps.
Cheers

Stainless Steel – Grade 904L

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.

Although originally developed for its resistance to sulphuric acid it also has a very high resistance to a wide range of environments. A PRE of 35 indicates that the material has good resistance to warm sea water and other high chloride environments. High nickel content results in a much better resistance to stress corrosion cracking than the standard austenitic grades. Copper adds resistance to sulphuric and other reducing acids, particularly in the very aggressive "mid concentration" range.

In most environments 904L has a corrosion performance intermediate between the standard austenitic grade 316L and the very highly alloyed 6% molybdenum and similar "super austenitic" grades.

In aggressive nitric acid 904L has less resistance than molybdenum-free grades such as 304L and 310L.

Which means Rolex will still rust !!! But not in normal circumstances

The older ones sure do!

[funkycatspangky]

if my rolex got wet from rain water or sea water, and if I wash it with tap water to clean it, will it prevent rust?

[nakedtoes]

are the bracelet also made from 904 steel?
