Apple Watch Series 7 low heart rate counts

[jeffjank33]

Any new Apple Watch 7 folks having issues where heart rate is low. I have to increase the tightness of the band way beyond what I did with Series 6/4/3 to get an accurate reading. How I've worn all the past Apple Watches, gets me really low readings, like 20% off from all other watches.

Anyone else having a similar issue?

The Series 7 uses the same sensors as the Series 6. Are you using the same band with the Series 7 as the Series 6? What kind of low readings are you getting?

Yup, exact same band I wore with my 4 & 6.

yup, understand most everything else is the same. Only thing I can think is the extra 1mm in size and what that relates to in contact pressure.

both resting and exercise seem about 20% lower unless I tighten band an extra notch which makes it border kind uncomfortable.

Must be a defect with mine versus a systemic issue as no one else seems to be having a problem... strange.

Mine is very consistent even while using the sport band. The loosest I own. Using S3, S4, S5 and last two days S7.
