I bought a Watch 2 on launch weekend and purchased a woven band in the Navy/Tahoe Blue color separately. I've used the woven band exclusively and noticed a very odd color change last week. I have NOT used it in extreme conditions such as swimming or even showering. Basically, one piece of the band has shifted color to a more purple color. It is extremely noticeable where the loop for tucking in the tab shoes against the other half while wearing it because they are two very different colors. This fact alone indicates it wasn't caused by exposure to something harmful while I was wearing it, since that loop should have changed color too of that were the case. there is a very faint difference in color on the tab half where the loop/buckle sots over it, but not much. I thought it might be caused by color bleed from a sleeve on new clothing, but that doesn't explain why only the loop would not have been affected (or the exposed part of the other half, since the tab side doesn't cover all of it while wearing.) I've just washed with a mild soap and have it drying right now, but even while wet, I can see that the two halves are completely different colors! Anyone else have this problem and if so, anyone have success returning? Apple.com doesn't list any kind of warrantee on the separately purchased bands.
