Rolex Adopts 904L Grade Stainless Steel

Rolex's decision to adopt 904L grade stainless steel marked a notable shift in the materials used in luxury watchmaking. Prior to this change, most Swiss watch manufacturers predominantly utilized 316L grade stainless steel, which, while durable, does not offer the same level of corrosion resistance as 904L. The introduction of 904L steel by Rolex provided several advantages, particularly in terms of longevity and aesthetic appeal. This grade of stainless steel is known for its superior resistance to rust and corrosion, making it particularly suitable for watches that are exposed to various environmental conditions. Additionally, when polished, 904L steel exhibits a distinctive and attractive lustre that enhances the overall appearance of the timepiece. However, it is important to note that 904L is softer than 316L, which can make it more susceptible to scratches, a trade-off that Rolex has accepted in pursuit of quality and visual appeal.
