Apple Watch rash

Is that rash occur under the band or is it under the watch? If the problem occurs under the band, you may want to try a band of a different material. Personally, I do not find the silicone bands comfortable. This is my current favorite - the Sport Loop: 41mm Lavender Gray/Light Lilac Sport Loop - Apple

No problems with this one!
