Apple Watch leaving burn marks on wrist

That happens from water and/or sweat. If you leave your watch on while washing your hands, going swimming, while exercising, etc. Then that happens. I found the best thing to do is after any water or sweat get under the band, take it off, dry it and your wrist, and then put it back once completely dry. I’ve experienced this with Apple Watch and Fitbit. Silicone bands and fabric. It’s the moisture.
