It was chosen as the material for watches because of its durability and resistance to corrosion.

However, many leading watchmakers prefer to alter the composition of the metal to create a material with superior performance. These alloys put watchmakers ahead of the competition and make their brands stand out.

Rolex is at the forefront of this, as it creates many in-house metals. For rose gold, they use a different alloy called Everose, in which platinum replaces the silver in the mix. Then there is Rolesor, half gold and half steel, a composite material that first appeared in 1933.

Rolex started using 904L in the 1980s, recognizing that it was a superior alloy to 316L, which was the industry standard for most watches. However, they only used this material for their line of dive cheap replica watches, the Rolex Sea-Dweller. Later, they also used 904L for the Submariner line.

Rolex found that while 316L stainless steel is corrosion resistant, salt water can still penetrate the case back and strap, eventually leading to rust and deterioration.

Oyster steel is scratch-resistant, plus it has some corrosion-resistant properties that protect it from moisture, not only in the field, but also on the wearer’s skin. In this respect, it has equal status with precious metals.

Brands like replica luxury watches Rolex are unwavering in their pursuit of looks, and Oyster Steel maintains an exceptional lustre that does not darken over time. Watchmakers ensure that the watch on your wrist will retain its “store window” lustre and always display the signature Rolex quality.

Compared to standard stainless steel, 904L is characterized by its outstanding corrosion resistance, which puts it in a class of its own, comparable to precious metals.

Rolex took note of this when it began using 904L in the 1980s. Its exceptional corrosion resistance protects the watch from premature wear of specific components caused by the intrusion of salt water and other minerals. Even just moisture on the wearer’s wrist can have an effect over several years.

By combining oyster steel with precious metals, Rolex has created an unparalleled combination of both performance and design aesthetics. Rolex’s mantra is “timeless”, and Oyster steel offers timeless quality with its resistance to corrosion and tarnishing. The performance of Oyster steel is unparalleled, and the patented name only reinforces Rolex’s unique exclusivity.
