I have an aluminum Apple Watch, I'm planning to buy a black link bracelet band for it. The link bracelet is made of stainless steel which is a metal and my watch is aluminum, also a metal. I'm afraid of the band scratching my watch when I'm changing the bands. Since you have to slide the bands out, I'm afraid that the friction between the band and Watch case will scratch it. Do you have an aluminum Watch with a link bracelet band? Did it scratch your case? Please let me know, my OCD is driving me crazy.
