S1 Black strap
I'm really impressed with the Zinvo watch I purchased. The quality is fantastic and the moving blade second hand is mesmerizing. It was indeed the perfection addition to a fairly large collection of watches that I own. I went ahead and pick up the S1 Black strap to go with it and it is of course the perfect match. If you're on the fence about a Zinvo watch or any of their additional straps, I say go for it! You'll be glad you did.
