Q

What materials does Rolex use?

I am using the Datejust Rolesor model. What is the Oyster Steel depicted on the official website? And how many carats does gold use?

A

The two main types of steel used by many watch brands are 316L and 904L.

Among these, Rolex uses the 904L grade, which is referred to as ‘Oyster Steel’ after undergoing unique processing while making watches. This grade has excellent anti-corrosion properties and is commonly used in the aerospace and chemical industries.
Additionally, it is said that the yellow gold and white gold used in Rolex watches are both 18 carats.
