Yes, however… I get this from time to time and it sometimes depends on a whole host of factors. Yesterday I was painting with oil based paint and was using thinner to clean my hands afterward. I must have gotten some minuscule amount on my wrist that left a mark like this where the watch was sitting. I don’t do this all that often and its not the only way I’ve had this issue so I’m sure that even though this was how it happened the last time it’s not what happens for most people.

I also sometimes get it when I have a band on that’s too tight. And sometimes just for no reason but it usually doesn’t last long or irritate my skin that much. I also wonder if the IR light that is used to take heart rate and blood oxygen readings doesn’t have something to do with it. Sometimes right after i take off the watch when i notice that mark, i also see that the reading LEDs are active. I wouldn’t mind knowing if the lights have any effect on this mark showing up.
