Why 904L Steel Becomes the Standard for Top Replicas
Rolex is one of the few brands using 904L steel, which outperforms common 316L in corrosion resistance and polish. Top replica factories now follow suit.
- Higher chromium, better corrosion resistance
- Brighter polish
- Harder and costlier to machine
Under the same light, 904L shows finer brushing and a more mirror-like polish.

Correct material is the first divider between top replicas and cheap fakes.
