Steel models of ordinary Swiss watches will use 316L steel, but Rolex is an exception, and its steel watches are made of 904L steel with higher toughness. For the knowledge of 904L steel, everyone maybe only stay on the surface of "wear-resistant and durable", and the difference between this steel and the 316L steel used by other watch brands is not clear. One thing is pretty sure, 904L steel will make the cost a bit higher.
People who play watches probably know the materials of watches. Common materials for watch cases include K-gold, titanium, and ceramic, of which stainless steel is the most common. 316L steel is not easy to cause allergies, and it is not easy to corrode and deform. It is mainly used in food processing and medical equipment. 904L steel is mainly used in equipment such as chemical reactors, seawater processors and other equipment exposed to highly corrosive substances, and its corrosion resistance is superior to that of 316L.
Rolex began manufacturing 904L steel watches in 1985 and gradually replaced it as the brand's standard. 904L steel contains more chromium, which can help form a protective anti-corrosion film on the surface of metallic materials. All of our super rolex cloned and high end are used in 904L stainless steel, which is same as real Rolex. If you are not allergic to metals, Rolex may be a brand you will not hesitate to choose. In addition, due to the high metal purity of 904L steel, it can be highly polished, so that a brighter and more beautiful effect can be obtained after grinding. It is said that Rolex can achieve 26 polishing times in its lifetime. Even with severe dents, it can be polished five times to a depth of 0.02mm. The secret behind this is that Rolex requires a higher purity of the steel used to remove impurities, leaving only the "purest" part in the middle. Rolex Steel watches, so to speak, will be never out of time!
