The 250-Ton Press Standard: Clean Factory employs a massive 250-ton press to stamp and shape our resilient 904L steel cases. While standard market versions opt for the cheaper and softer 316L stainless steel, we remain steadfast in our commitment to genuine 904L Steel (often referred to as Oystersteel). This superalloy blends seamlessly with our other premium components, achieving an exquisite finish that mirrors the genuine model’s weight and feel.
Why 904L Matters (Vs. 316L): The distinction places Clean Factory watches in an elite league. Unlike 316L, 904L steel is notoriously difficult to machine due to its hardness, requiring specialized tools. However, the result is worth the effort: after polishing, 904L steel exhibits a unique, warm luster and a brilliant shine that 316L simply cannot match. This specific visual “glow” is the hallmark of a high-end luxury timepiece.
Superior Corrosion Resistance: Originally designed for the aerospace and chemical industries, 904L steel contains higher levels of chromium, molybdenum, and nickel and copper. This grants it formidable resistance against the harshest environments. Whether it is saltwater from the ocean or acidic perspiration from daily wear, our 904L cases remain pristine and rust-free, ensuring your watch looks brand new for decades.
