“Technically speaking, Patek Philippe watches are all hand-made and finished, whereas many pieces, even such as (those produced by) Rolex or Omega, typically are finished by machine,” Clymer says.
Then Is 904L harder than 316L? Type 904L contains more chromium, molybdenum and nickel then 316L, plus also some copper, manganese and silicon, which makes it more corrosion resistant than 316L. But the main issue with 904L, besides its extremely high price, is that it is still harder to process than 316L.
Furthermore, Why are Pateks so expensive?
The manufacturer only uses stainless steel for a small selection of watches. … The way Patek Philippe watches are created means their production takes longer, resulting in lower inventories than most other luxury brands. This makes Patek Philippe watches highly exclusive and, thus, expensive.
What is the Holy Trinity of watches? Each brand is constantly fighting for a legacy of greatness. The big 3 watchmakers in the world are Audemars Piguet, Patek Philippe, and Vacheron Constantin.

The Swiss Stern family has owned Patek Philippe since 1932 when Charles Stern and Jean Stern acquired the company during the Great Depression.
Is 904L super duplex?
The corrosion resistance of 904L is equivalent to most super duplex stainless steels (SDSS) across a wide range of applications. … At low temperatures, 904L will retain good impact toughness, and it is not at risk of forming deleterious intermetallic phases at higher temperatures.
Does 904L steel scratch easily?
904L is softer and scratches easier as others have said. I find that 904L has a different look/sheen or glow about it vs the 316 of other watches.
Is 904L steel magnetic?
Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum. The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.

What material is S31803?
Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels.
What is pren value?
Pitting resistance equivalent number (PREN) is a predictive measurement of a stainless steel’s resistance to localized pitting corrosion based on its chemical composition. In general: the higher PREN-value, the more resistant is the stainless steel to localized pitting corrosion by chloride.
What is uns31803?
General Duplex stainless steel information
2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength.
Why does Rolex use 904L steel?
Since salt is generally the culprit behind rusting and pitting, Rolex decided to make the switch to 904L. The material is actually more resistant to all chemicals (not just chloride.) Switching to 904L allowed them to offer a better product that was could handle serious stress.
Can 904L steel rust?
904L stainless steel is harder and does not machine well than other steels used in watches. … In addition to higher rust, corrosion, and pitting resistance, 904L polishes quite well with the correct tools and know-how.
Does Omega use 904L steel?
Omega utilize 316L stainless steel, which is the industry standard, yet Rolex utilize 904L stainless steel, which offers greater resistance to corrosion and can resist polishing extremely well, making it easier to maintain in the long term.
How hard is 904L steel?
Its popularity in these areas comes from the properties which make it resistant to rust and corrosion. 904L steel takes the resistance to corrosion up a notch.
…
316L VS 904L Steel Composition:
| 316L Steel | 904L Steel | |
|---|---|---|
| Hardness (Rockwell) | 95 | 70-90 |
| Hardness (Brinell) | 217 | 150 |
What is 904L material?
Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
