good info there.

904l steel is still steel and quite soft. if you want to resist scratches then you should try ceramic the down side to that is it breaks in strong impact.

if you are worried about the softness of 904L steel, you should not even think about getting a gold watch....

No matter the material the watch is made from it will get digs and scratches when worn that's a fact.There is nothing magical about 904L steel it was developed for industries that use acid type products.Now although its a bit more corrosion resistant over 306L but with today's Rolex wearers and in general pampered watches it has no real advantage if watch follows normal routine service at RSC.Now if you have your watch in a stronger than normal acid solution or in salt water 24/7 then it could be a slight advantage.The 904L SS is not harder than the watch industry norm 306L in general hardness come from how the metal is tempered.In some ways 904L has disadvantages over 316L as 904L will scratch and show scratches more easily.Sure 904L costs more but that's down mainly to demand, far more 316L is sold over the 904L. Rolex used to quote at one time it costs more, and take 12 months to make a Rolex oyster which IMHO was just a brag factor.Now the only difference between 316L over 904L it has slightly more Molybdenum(Mo)approx 2% more, approx 1-2% more Crome(Cr),approx 1% more copper(Cu) and approx 10% more nickel and that's it all quite low cost materials.

To the OP.

You just need to be more careful.
Too hard on the gear.
