Do you have any information as to when Rolex started incorporating 904L in the GMTII line and is there a way to tell on the bracelet?
Thanks

The 116710LN was the first GMT model to have a 904L bracelet. Anything prior was 316L even on models with 904L cases. The rule of thumb is that no "tuna can" clasp / hollow link bracelet was 904L.
Fun fact; Rolex used to source their 316L from Sandvik in Sweden before making their own 904L alloy in-house.
