I haven't had any staining problems. You will, however, notice a patina. The leather will darken with time. Love the band. I have an extra, brand new in box if you're looking for a 42mm version... PM me if interested
Updated pics. My above band had lug connector issues and so I got a replacement. The new band is even better than above band in leather quality and fit. I also like the darker smoother texture.
Isn't that a bit tight for you?
Congratulations with your new strap - You have been looking at it for ages right? Looks great... Still would have loved it if Apple would have made Space Black adapters for us with the Black Stainless Steel... Well guess they saved me some money
