Apple Watch Band Choices

So, I've been doing some research online and I've found a number of people that have tried the Space Gray Sport watch with silver metal bands. Doesn't look the greatest in my opinion. What I'm wondering is if anyone has tried the Silver sport watch with the black metal band options, or any after market black metal bands. I thought this would probably look ok since they have historically paired a lot of black bands with silver aluminum and silver stainless steel watches.

I really don't like the idea of doing a silver metal band with the aluminum watch because the metal's don't quite match which I think probably looks worse than if you just contrast it by going with a much different color.

Essentially, I'm looking for opinions here on what would look ok and what wouldn't. Pictures of band / watch combinations would be cool too.
