I noticed in photos that my left wrist looked significantly thicker in old photos compared to now. I usually work out with it on and wear it snug (not tight). After going to bed I take it off and notice an indent on my wrist. Anyone else get this? Is it bad long term?
You are actually wearing your watch correctly, don’t listen to people saying loosen it. Heart monitor watches should be worn snug to leave a bit of indent/marks to function correctly.
I Have had no issues getting a heart reading when it’s just making contact with skin. It doesn’t need to press into your body.
