Here's some information about 904L steel. I think you were unlucky to catch the fall at a bad angle. I've banged my GMT up against granite countertop a couple of times with no dings or scratches.

Well ... as has been noted by others in this forum 904L is softer. Even the terminology of "it takes a polish better" means that too.

Ive cape cod polished my BLNR with ease, also scuffed it with ease compared to 316L watches.

Not overly fussed but the only benefit is the corrosion resistance and thats at the downfall of hardness.

Of course Rolex today portrays 904L as "Super Alloy" now they call it Oystersteel, but whether its made of 316L or 904L does it really matter Rolex first introduced 904L around 1987 with models like the 168000 Sub.But many thousands of vintage Rolex are still in this world today with the industry norm 316L.Same could be said of the millions upon millions of high end and other Swiss watches in this world today that use 316L.The only difference between the 316L and 904L is its higher nickel content.Plus its slightly higher resistance to strong acids like sulphuric acid what 904L was developed for.And it has a slightly higher resistance to salt water.So if you don't regularly live 24/7 underwater or expose your watch to strong acids in the real world IMHO no real advantage only the bragging factor by Rolex,a secret just keep them clean no matter the metal.

Below is a quote from a Rolex employee back in 2002 but might have altered now but would doubt if Rolex would say so.

Quote from Rolex employee in 2002.
At the moment, we have several companies all over the world, serving our needs for stainless steel. The watch case backs and bracelets are all made of (X2CrNiMo17-12-2 S. steel)( now that is the formula for 316L) which is the best compromise between the attributes of the variant materials. As usual, the steel is melted under vacuum, so we get an very pure base, which is easy to handle and allows an perfect polishing. I think, the same procedure as in every good gold manufacturing company.

My SubC's steel feels really soft but only when I compare it to my Omega DSOTM. 8x harder and zero scratches :P

My wife just asked me, "are you ok?!" and I lied to her that I hit my toe on something because I didn't want to admit that the loud weird pained grunting sound I just made, which she heard from the kitchen, was my reaction to your Rolex ding photo.
