What stainless steel does Seiko use?
Seiko like virtually all stainless steel watch manufacturers uses 316L. It is a steel specially formulated to resist attack by both high and low PH materials. Rolex uses 904L which supposedly has even higher resistance. However, 904L is softer than 316L.
What steel does Grand Seiko use?
316L stainless steel
The vast majority of Grand Seiko watches are made of 316L stainless steel, which is generally regarded as the industry standard. 316L is known for its low carbon content (in fact, that’s what the “L” denotes), anti-magnetic properties, and its excellent resistance against corrosion.
What kind of stainless steel does Rolex use?
904L steel
That is why Rolex uses Oystersteel, a steel alloy specific to the brand. Oystersteel belongs to the 904L steel family, which is particularly resistant to corrosion and acquires an exceptional sheen when polished. 904L steels are commonly used in high-technology and in the aerospace and chemical industries.
Why is Seiko cheap?
Why is Seiko 5 so Cheap? Call it Japanese efficiency! A lot of the parts and toolings are older and paid off, and the construction of the movement is mostly mechanized. This is especially true of the 7S26 movement.
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.
Are Seiko and Grand Seiko the same company?

Does Rolex stainless steel tarnish?

Is stainless steel better than white gold?
Stainless steel, in its soft, fully annealed state is about 155 Vickers, but at full hardening can reach 390 Vickers, which is 70 percent harder than platinum or white gold. This means that stainless steel will resist wear, dents, dings, and scratches better than either white gold or platinum.
What steel are Rolex watches made of?
Rolex has another blurb on their brand history page that claims they use their own alloy of 904L steel: “Rolex’s steel watches are manufactured from Rolex’s own 904L alloy, known as “Oystersteel” from 2018.” This is interesting because one would assume an alloy is determined by the properties that compose it.
What is the difference between Grand Seiko and Rolex?

On the other hand, Rolex was established in 1905 and established itself as a high-end watch manufacturer early in the company’s history.
What type of stainless steel is used in watches?
The industry standard stainless steel is 316L. In addition to watches, this alloy is also commonly used in the food industry, the medical field, and a wide variety of water and marine applications. You may see some watch brands refer to 316L as surgical grade steel or marine grade steel.
When did Rolex start using 904L steel in their watches?
