Used the band that came with it for awhile but got annoyed that it was scratching my laptop. Switched to a nylon band with an off center hook and loop buckle that has so far protected my laptop, but it looks like it’s giving me a bit of a rash after less than a week of use. I do wear my watch all the time, only taking it off to charge while I’m in the shower.
Used both Apple Watch and MacBook x years, never had a problem with scratching. Maybe you should post a pic so we can understand.
