I posted about it before but this time I was able to get a picture of it happening. I do have super thin arms but the watch is on its tightest setting. Anyone else have this issue? This was taken yesterday. It was 65 outside.




It’s an Apple Watch series 4

Switch to one of the sport loops, they're infinitely adjustable, and perhaps you'll be able to get the watch in closer contact with your wrist. Also they're way more comfortable than the Sport Bands.

Thanks for the suggestion! I hope that helps out

[doublepost=1553982597][/doublepost]Yes! I was desperate about this. I had an AW2 and never happened. My new AW4 did it every time since day 1 ! So Frustrating! I thought it was a related band issue (tightness) but no, even with the sport loop I had this issue. BUT (finger crossed) it seems 5.2 solved it!! Al least for me. I’m on my 6th try, no more gray during workout. Never. Have you 5.2 installed? (I hope not, let me believe 5.2 has solved, as i’ve Noticed)

Maybe it is too far up your arm and away from the pulse area?
There is no pulse area. Optical readers measure capillary refill and will work anywhere with good skin contact. This is evidenced by the arm bands for AW as well as Scosche and other optical HR readers on the market.

Also, check that you don't have Workout Power saving mode enabled. This saves power by disabling the heart rate sensor when you are doing a workout
