I didn’t noticed this was happening with my blue one as well. I’ve been wearing it on and off and to be honest even with my OCD, it’s not that noticeable to me. I would say this band has become my favorite since it’s so durable and comfortable. I do notice the inside color have changed a little probably from wrist sweat, but then again I’ve never washed it before. I’d say just enjoy it! The wear is most likely from putting on jackets and all since that part sticks out of the watch a bit. Bound to happen!Here you can see the marked thread of this side. It's easy to fray out
