Rolex, 904L'yi saat \u00fcretimine koyan ilk \u015firketti. 1985 y\u0131l\u0131nda Rolex, 316L \u00e7eli\u011fin yerine 904L \u00e7elikten yap\u0131lm\u0131\u015f saat kasas\u0131 \u00fcretti. 904L \u00e7eli\u011fi daha fazla krom i\u00e7erir, bu da metal malzemelerin y\u00fczeyinde korozyona dayan\u0131kl\u0131 bir kaplama olu\u015fturmaya yard\u0131mc\u0131 olur.
