Well, from someone who has owned a SS Black, if you scratch it, it doesn't go away. It was also harder to make it look good with all types of bands. Just looked like a big black square on your wrist with no two tone look at all. I think the SS is a better choice. You can polish scratches out and it works with a lot more bands.
So, I am so tempted to buy the Apple Watch HermèsStainless Steel Case with Fauve Barenia Leather Single Tour.
If I am spending $700 for a SS watch, might as well double it to get a nice one. But then, part of me says just get the SS with the leather bandfor $700. Why spend so much extra on a Hermes.....:/
