the black sport band is peeling inside so I called it in. Come to find out the bands are under 1 year warranty and they could replace it. It wasn't really a walk in the park because they wanted me to go to an Apple Store to get it replaced. At first they said if they ship it they would charge me $50. I said what kind of warranty charges you? With enough patience and bit of a pushback they agreed to send me a replacement via shipping to my door for free!!! Well for how much this watch is it ain't supposed to be falling apart within 2 months of use. So yea get your replacement sport bands exchanged if they are peeling.
