I'm talking about the Stainless Black. It has a DLC (Diamond Like Carbon) that gives it that black appearance. It is extremely durable. The only thing is, in manufacturing, the tiny little edge just beyond the screen must be easy for them to nick as I have seen quite a few watches, even non-black versions that have little marks around the screen.
It shouldn't get worse on the DLC Stainless like on the aluminum watch. If you get one really bad out of the box, just try another one.
You should be much more satisfied with the durability.
The longest I had one of the Stainless black watches was 11 months, it still looked like I had taken it out of the box. I had to get replacement because the back fell off the watch.
