I thought it would be jet black. Like the jet black iPhone 7. But to me it more closely resembles the finish of the stainless steel band of the iPhone X/Xs/Max.
My Space Black Stainless AW4 is black!
My son reckons it looks like dark chrome.
It sort of alters the appeal based on the reflection of the light. It can look more a like a high gloss black in lower light and more of a ‘Gun-metal black’ In Lower light conditions. It’s one of the most unique bands with its color status, and by far my favorite band.
